Photography With UV Light

From Alice Abela, a wildlife biologist from Santa Barbara County:

"Can you remind me how you image the specimen (scorpion) under UV such that the background isn't also lit? i'm thankful, - Marshal

alice_abela commented:

You need a black light with a 365nm wave length to illuminate the subject then do a really low intensity flash. This was a 2 second exposure at ISO 500. I set the flash on manual and probably had it at around 1/32 or 1/64. I usually have to play a bit with the exposure duration, flash, and ISO to find the combination that works best for the shot and I kind of paint the subject with the flashlight during the exposure to get even illumination. Hope this helps! a black light with a 365nm wave length to illuminate the subject then do a really low intensity flash. This was a 2 second exposure at ISO 500.

Mozambique - iNaturalist World Tour

Mozambique is the 88th stop on the iNaturalist World Tour. The top observer is @snidge with observations clustered around central Mozambique north of Beira along with other top observers such as @graeme and @judygva. @i_c_riddell, a Safari Guide throughout Zimbabwe, has Mozambique observations clustered here but his icon is pulled towards Zimbabwe by his observations there. There's another cluster of top observers to the south along the border with South Africa and near the capital of Maputo including @andrewdeacon (who worked for many years at South African National Parks), @seastung (a marine naturalist from cape town), and @ricky_taylor (with an interest in coastal ecosystems between the Tugela River and Maputo). A third cluster of observers are located to the north of the country such as @tomaschipiriburuwate, @francescocecere, and @ldacosta.

There's an interesting peak around 2014
which was driven mostly by @snidge, @graeme, @i_c_riddell, and @andrewdeacon and then a lull until things started ticking up again in mid 2017. This timing coincides with the arrival of the Southern African community formerly using iSpot.

The top identifier is @jakob who does research across the African continent. @cabintom leads in insect IDs, @johnnybirder leads in bird IDs, and @ricky_taylor leads in plant IDs. @tonyrebelo and @alanhorstmann, based in South Africa are also top identifiers.

What can we do to get more people in Mozambique using iNaturalist? Please share your thoughts below or on this forum thread.

@snidge @andrewdeacon @graeme @seastung @judygva @jakob @cabintom @johnnybirder @tonyrebelo @alanhorstmann

We’ll be back tomorrow in the Kazakhstan!

Summary of the 2019 CVC Butterfly Blitz

As the organizers of the 2019 CVC Butterfly Blitz, @lindseyjennings, @lchung and myself would like to say a great big THANK YOU to all of you for participating! Whether you contributed one butterfly sighting or 100, you were an important part of our project.

Here’s a quick summary of what we found this year:

• Between June 22 and August 24, there were 1,157 observations of 57 different butterfly species added to our iNaturalist project
• We saw a 600% increase in the number of butterfly observations submitted to iNaturalist in the Credit River Watershed for 2019 compared to 2018; this is significantly higher than the average increase of 68% in observations in other taxonomic groups in the watershed over the same time period
• For 44 of the 57 butterfly species observed, we increased the number of observations on iNaturalist by 50% or more; for example, Common Wood Nymph had 5 records in the watershed before 2019 and 33 records from 2019
• We added the first observations on iNaturalist in the watershed for five butterfly species (Dion Skipper, Crossline Skipper, Mulberry Wing, Acadian Hairstreak, Giant Swallowtail)
• We observed a provincially rare butterfly species (Black Dash) and one species that hadn’t been reported from the watershed in 20 years (Dion Skipper)
• In our one-day butterfly count on June 29th, 18 people recorded 476 butterflies from 26 species at nine sites in the upper watershed; the data from this count was submitted to the North American Butterfly Association
• Throughout the summer, six people completed 33 timed surveys and recorded 1118 butterflies from 44 species; these data were submitted to eButterfly

All together, we collected over 2500 records of 57 butterfly species in the Credit River Watershed – a wonderful amount of data on an under-surveyed group. As we repeat the Butterfly Blitz over time, the data will help us track trends and provide insights to help protect and restore wildlife habitat in the Credit River Watershed.

For more summaries of the Butterfly Blitz, check out our CVC blog post here: and the presentation we gave at the August 24th wrap up event here:

If you’re interested in learning more about the Butterfly Blitz or would like to know how to get involved next year, contact Lindsey Jennings:, 905-670-1615 ext. 445.

Logging Hours for FPWC and SDNC

Hello Citizen Scientists,

I am so impressed with all of our data collection this summer! We have documented a wide variety of species across the county. I appreciate all of the hard work you put in.

Since peak citizen science period for our programs is winding down (not that you should slow your iNaturalist activity), I am working on collecting information about our volunteers and how much time they have invested into these projects.

If you are not already an official volunteer for Forest Preserves of Winnebago County or Severson Dells Nature Center, I would really appreciate it if you followed this link to fill out an online application: This will help us track your hours and use that information to secure funding from grants!

Once you fill out the application, FPWC and SDNC staff will work together to get you set up with a Volgistics account where you can log your hours.

If you already have a Volgistics account but don't know how to navigate it, feel free to reach out to me at the SDNC office (815-335-2915) or to

I know this may seem like an extra hoop to jump through, but this will really help us out. Thank you so much!

How to use this project

Observations added to this project must be linked in the observation fields such that photos of the arthropod visitor are paired with a photos of the visited flower, ideally using duplicates of the same photos. For example, if I photographed Bombus impatiens visiting Helianthus tuberosus, I would take the following steps:

1. Upload the photo(s)
2. Identify the observation as B. impatiens
3. Duplicate the observation
4. Identify the duplicate observation as H. tuberosus
5. In the Observation Fields section, add the "linked observation" field; paste in the URL of the H. tuberosus observation into the linked observation field of the B. impatiens observations, and paste the URL of the B. impatiens observation into that of the H. tuberosus observation.
6. Add each observation to our project, Arthropod-Flower Associations

If you have any difficulties with this workflow, or any questions or comments about the project, please feel free to contact me at Thanks for your efforts!

This relates to the following observation submitted by @vynbos:

Let’s use the “spanner” to fix things.

This observation and my own responses to it provide some insights into this challenging business of identifying droppings. I don’t really want to turn this journal facility into a blog, but I think others may benefit from the thoughts below. I have.


I looked at the pics initially and couldn’t immediately decide whether this was a cat or not (which is why I said initially “while I give this one some thought”). I studied my own published and unpublished cat pics and thought, “well, they could be”.

I saw, and wondered about the substrate, the flattened dry vegetation. “Would a cat do its thing on that?”. It didn’t look right. (This business is a lot about inconclusive feelings, I’m afraid.) A canis species would use such a substrate, I felt.

Then it occurred to me that it was a multiple deposit. A cat producing a multiple deposit?! But the general “rule” is: “they don’t use latrines”. Wow, that’s interesting. And it is just possible, and I gave the (rarely observed) reasons.

What rule did I break you ask? The principle of Occam’s Razor.

The principle: If there are two explanations for something, the simplest one is usually correct.

Two possible explanations are:

(1) The multiple deposits (on what seemed an unusual substrate) were possibly a black-footed cat (which is quite scarce) near a den or a wildcat (which rarely does this).
(2) It’s not a cat, but some other carnivore.

Explanation (2) is the simplest.


I had looked at the map and zoomed in to the best resolution it could give. I even did it in my Google Earth (although the map is the same, GE is more flexible). I noticed the buildings to the south east but made the mistake of not measuring the distance to those buildings. I see now they are only about 500 m away. That should have been at least a red light that a domestic animal could not necessarily be ruled out (whether canis or felis).

I’m still in a bit of that mode in which I have to remind myself frequently that domestic animals are important to consider in this business. (To this end, I included some of them recently in my database of quantitative data, so they appear automatically now. But some refinement is necessary.)
Domestic dogs and especially cats even appear in species lists for some protected areas or are known to have been present but are not recorded in lists.

IN MY DEFENCE (he adds timidly)

Another principle (long used in various other contexts, I see from Google) that I still frequently remind myself of, is this:

“When it concerns animal behaviour, always remember never to use the words always and never.”

[ In the above case, this conveniently negates Occam’s Razor! But let’s not go there. :-) ]

Don’t underestimate this principle. I have seen examples of this over the years. (Just one: Once, and only once, a single unquestionable aardwolf dropping, unburied, on the edge of a dirt road. The “rule” is: They bury them in middens. The lack of adherence to the rule might be easily explained, of course: when you gotta go, you gotta go.)

But, generally speaking, the problem with animals is they don’t read the guidebooks we write about them. If only they would. They might then follow the rules more closely. Our lives would be much simpler.

The only relevance this has to the above-mentioned observation is that one shouldn’t ignore the unusual in this business.

However, I hasten to add, maybe Occam’s Razor should have more prominence than it’s been getting.

Kleinmond: 1) Red List Spp 2) 3S Ridge - species of interest

Of interest to KB CREW, the redlisted plants noted by us. No doubt still work in progress. We are adding it to the Red List Project as obs are uploaded. There were some divine plants on the 3S Ridge and I added a note below.

Weer eens verskriklike groot dankie vir jou gasvrye plant wys en saamkyk. Dit was beslis 'n hoogtepunt en nog lekkerder om daarvan in my moedertaal te kon doen saam met jou!

The informal tea, iNat demo and general dicussion added value too and I think this kind of collaboration should not be underestimated as a way to support and strenghten CREW nodes.

I am inordinately uncomfortable using online and social media. If this of interest to KB, copy - lest I delete it at some stage!

Sexual Cannibalism in Praying Mantises

Insect world continues to fascinate us with the diversity in all aspects. Insects have amazing adaptability, strength in comparison to body size, ability for metamorphosis, and so on.

Praying mantis are one cool and photogenic group due to their eyes, face posture and forearms. I love watching them and can spend a lot of time just looking at their movement or feeding style.

While walking casually between two university buildings, I noticed some insect in the grass. From a distance I thought it was a grasshopper or Katydid. But I decided to take a closer look. It was a Praying Mantis.

But it looked a little different. I then realized it was not single insect but was a mating pair. But then the male looked weird. It took some time for me to realize that the head of the male was missing.

I immediately remembered reading about sexual cannibalism in mantises. But I was thinking it happens after the mating is complete. The females many times catches and eats the males. There are different theories about this. In most predatory species this is observed. It is a very high percentage in captivity but is known to occur in the wild in about a fourth of times.

I never thought that I would get to see such an event in wild myself. Most interesting thing was the mating was still in progress even though the male was headless. And half an hour that I observed the male was still in the same position and the female was not attempting to attach further.

It is a Carolina Mantis (Stagmomantis carolina) in Mantids Family (Mantidae)

Update: Thanks @mantodea for id confirmation.

Hungary - iNaturalist World Tour

Hungary is the 87th stop on the iNaturalist World Tour. The top observer, @philsansum, has observations clustered in the northeastern part of Hungary along with @beidts, @ahospers, and @deserti around places like Bükki National Park and Hortobágy National Park. The second top observer, @veszt is a biologist and plant breeder from Hungary, his observations are distributed widely across the country. There is a cluster of observers such as @rudynature and @ikomposzt around the capital of Budapest and other users such as @gergely_katona clustered around Debrecen, Hungary's second largest city after Budapest. @balzs9's observations are clustered on the shores of Lake Balaton, the largest lake in Central Europe. @cathyp is currently 10th on the leaderboard but doesn't show up on the map since her observations are mostly from September of this year and the figure was last updated on September 1st.

The number of observations per month jumped up in the summer of 2018 and again in 2019.

In addition to being a top observer, @veszt is the top identifier and leads in plant identifications. @cossus and @ldacosta lead in insect and bird IDs respectively. Thanks to other top identifiers such as @kastani and @cs_melitta.

What can we do to get more people in Hungary using iNaturalist? Please share your thoughts below or on this forum thread.

Results (so far) from California Biodiversity Day in the Wilderness Park

Well, we didn't have a huge turnout of observers, but we have so far logged fifty observations made in the Wilderness Park on California Biodiversity Day. (Actually, it should be "Days", as California counted observations made on both Sept. 7 and Sept. 8.)

Among the fifty observations, were 40 different species, including 16 species that were new to this project, which is great! You can check them all out here.

You can also see photos of Friends at the Park on the Friends' blog.

If you have observations from Sept. 7 and 8 that you haven't posted yet, don't worry. We will keep collecting them indefinitely. And all Observations made in California on those days (including the ones from the Wilderness Park) are also collected on the statewide California Biodiversity Day project run by the California Department of Natural Resources.

We plan on having an event in the Wilderness Park for next year's California Biodiversity Day. For 2020, September 7 falls on Labor Day, which is a Monday, and I am assuming the state will count Sunday, Sept. 6, and maybe Saturday, September 7, as well. We also plan to have an event in the Wilderness Park for the City Nature Challenge on April 24-27. Observations made in the Park will count for LA County, which enters as a "City". Mark these dates on your calendar now!

Angeles National Forest Trip

We did a simple hike along the Gabrielino trail that started from the Red Box Trailhead. There's a pretty cute little museum called the Haramokngna American Indian Cultural Center.

Some highlights:

Fuzzy things on these plant. iNat says it's a mountain mahogany? Neat!

Pretty pinecone covered in sap. A type of douglas fir I guess?

Pretty berries. Algorithm says it's a Southern Honeysuckle, and endemic if so. Very cool!

Disembodied deer leg we found near this weather station surrounded by boarded up houses. Spooky!

Definitely my favorite find of the trip. What's most likely a Big Berry Manzanita. Very pretty plant and the peeling bark looks awesome.

La Jolla Trip

Went to La Jolla about a week and a half ago!

Some highlights:

Nursing sea lion

Spotting a harbor seal from far away (didn't get to see them up close on this trip or my previous one)

The cool lo-fi effect in general from shooting through a binocular lens. Brandt's Cormorant featured here.

Another photo I liked. Just a regular ol' sea lion.

A stray Heermann's Gull. I recognized this guy from a previous trip to San Clemente which is where I encountered them for the first time.

A ground squirrel! Not a great photo or particularly interesting but it was my first time getting a photo of one as I usually live deep in the city and don't see them often.

Topic: ERS 246 Outing #1

Time and Date: 19/09/18 12:25
Duration: 45 minutes
Location: Waterloo Park, Waterloo, ON
Weather: Sunny and 24 degrees
Habitat: Pond, trails, garden

I went for a walk around Waterloo park in the Afternoon. There were many people biking and walking along the paths. I noticed a lot of Canada goldenrod throughout the entirety of my walk. The main three areas I focused my observations around were around silver lake, the garden surrounding the east gazebo, and along the LRT tracks. There was a group of people feeding mallards and Canadian geese breadcrumbs along the waterfront which also attracted squirrels. Two great blue herons were perched on a log and a rock in the middle of silver lake. I tried to see what fish might have attracted them to this pond but could not see much from my vantage point. Throughout my walk I heard other bird calls as well but was unable to identify which species produced these calls (something to practice!). I saw pollinators such as monarchs and the common eastern bumble bee in the garden area surrounding the gazebo. They were attracted to the hydrangeas and black-eyed Susan which were in bloom.

This first field journal made me much more conscious of the impact’s humans have in a natural park area like Waterloo park. A few examples of this are: the excessive amount of wild carrot (native to Europe and Asia), the fragmentation caused by the LRT tracks, bird feeders, people feeding wildlife, and gardens planted with non-native flowers (Chickory).

North America Has Lost 3 Billion Birds, Scientists Say.

Over the past half-century, North America has lost more than a quarter of its entire bird population, or around 3 billion birds.

That's according to a new estimate published in the journal Science by researchers who brought together a variety of information that has been collected on 529 bird species since 1970.

Why I keep my time zone set to Arizona

Even though I live in California, I prefer to keep all my clocks set to Arizona/Phoenix timezone also know as Mountain Standard Time.

Arizona Time is identical to Pacific Daylight Time during the summer and autumn and it never changes, unlike other time zones. This means that it is never necessary to reset clocks twice per year which, in my opinion, is insane.

One benefit of using Arizona Time year round is that, during Winter when the clocks "fall back" one hour, I never lose that crucial hour of daylight in the evening. This means that I can still enjoy walks in the evening while it is light out, whereas most people are still at work or just coming home from work at that time.

Another benefit is that I do not experience the gloom associated with losing that crucial hour of evening light in the Winter. This makes the Winter seem a lot more pleasant. I also strongly feel that it's a grave mistake to mess with the clock and our body's daily synchronization.

One final benefit which I really enjoy is that during the time of year in Winter when my clock is off by an hour it gives me an extra hour to prepare for things. If for example I have an appointment scheduled for 9 a.m. on everyone else's time, that actually means it is at 10 a.m. my time.

Once you get used to the difference it is easy to keep track of it. One thing I do for appointments during that time of year is put a little notation in my calendar events noting the time in "their time" which I abbreviate TT. So that 9 a.m. appointment would get put into my calendar as 10 a.m. but I would also put in a note "9 a.m. TT".

Venezuela: catálogos de especies

En esta sección, encontrará los enlaces a los catálogos digitales de especies derivados de los proyectos listados en el artículo 'Datos de Venezuela en iNat: ¿con qué contamos?' (ver enlace al final de esta nota). Los mismos han sido elaborados a partir de los registros 'grado de investigación' cargados en la plataforma.

Estas listas digitales de organismos son muy útiles para la identificación de los mismos, así como también nos ofrecen un excelente mecanismo para mejorar y afinar nuestras habilidades de identificación en campo, convirtiéndose en una poderosa herramienta de entrenamiento.

¿Por qué es importante acotar en las observaciones que un organismo ha sido cultivado o corresponde a un animal cautivo?
Porque iNat se trata principalmente de la observación de organismos silvestres, no de animales en zoológicos, plantas de jardín, especímenes en cajones, etc.; y los socios de datos científicos de la plataforma a menudo no están interesados en ese tipo de registros.

Si tiene sospechas o cuenta con información de que un registro es de una planta cultivada, un animal en cautiverio y/o mascota, por favor indíquelo en la sección 'Evaluación y Calidad de Datos'. De igual forma, exhortamos a indagar con los autores de las observaciones sobre este aspecto y de obtener respuesta, señalarlo en el aparte antes mencionado.

***English version***

In this section, you will find links to the digital catalogs of species derived from the projects listed in the article 'Datos de Venezuela en iNat: ¿con qué contamos?' (see link at the end of this note). They have been prepared from the 'research grade' records loaded on the platform.

These digital lists of organisms are very useful for their identification, as well as offering us an excellent mechanism to improve and refine our identification skills in the field, becoming a powerful training tool.

Captive / cultivated (planted): checking captive / cultivated means that the observation is of an organism that exists in the time and place it was observed because humans intended it to be then and there. Likewise, wild / naturalized organisms exist in particular times and places because they intended to do so (or because of intention of another wild organism). The main reason we try to flag things like this is because iNat is primarily about observing wild organisms, not animals in zoos, garden plants, specimens in drawers, etc., and the scientific data partners are often not interested in (or downright alarmed by) observations of captive or cultivated organisms.

ARbutus xalapensis Kunth in H.B.M. y A. occidentalis McVaugh & Rosatti se han interpretado como taxa particularmen-te polimórficos. Estos son un buen ejemplo de grupos en los que resulta difícil la aplicación de conceptos de especie, cuya correcta interpretación es de gran interés para entender los patrones y procesos de la evolución (McDade, 1995)


Durante el tratamiento de Ericaceae para la Flora del Bajío y regiones adya-centes, se encontró que los Arbutus de porte arbustivo que crecen en las cercanías de la ciudad de Guanajuato, México, la localidad tipo de A. mollis Kunth in H.B.K., no corresponden a un sinónimo de A. xalapensis, como tradicionalmente se ha acep-tado, sino que forman parte de lo que ha sido considerado como A. occidentalis var. villosa McVaugh & Rosatti y, por lo tanto, Arbutus mollis es el nombre más antiguo que debe aplicarse a ese grupo de plantas. La revisión taxonómica de las plantas que han sido consideradas como parte de Arbutus occidentalis reveló que bajo ese nom-bre se han incluido a algunas que comparten el hábito arbustivo pero que difieren en varios aspectos, y que las dos variedades descritas por McVaugh y Rosatti (A. occi-dentalis var. occidentalis y A. occidentalis var. villosa) y posteriormente reducidas a sinonimia por Sørensen (1995), representan en realidad dos taxa independientes, a los que se reconoce aquí con la categoría de especie.

Observations: The Last Butterflies?

The Last Butterflies?
If the Trump administration weakens the Endangered Species Act, many populations that are already dwindling will disappear
By Nick Haddad on September 19, 2019

A recent U.N. panel on biodiversity reported that there are one million species currently threatened with extinction. Most of those are the insects that make up two-thirds of the earth’s species. What we know about these vanishing insects is largely informed by scientific studies that show the alarming, decades-long decline of butterflies, including those listed under the Endangered Species Act.

As a conservation biologist, studying these butterflies has been my life’s work, and I am deeply troubled by the disastrous modifications to the Endangered Species Act recently announced by the Trump administration. Indeed, the changes could jeopardize one of the act’s signature successes: that no listed butterfly has yet gone extinct.

Nick Haddad is a professor and senior terrestrial ecologist in the Department of Integrative Biology and the W. K. Kellogg Biological Station at Michigan State University. He is the author of The Last Butterflies: A Scientist's Quest to Save a Rare and Vanishing Creature (Princeton University Press, 2019).

Marine Life assessment

Hi guys,

We need your help to assess the marine biodiversity of Carriacou! This database will help us to monitor the species we find here and also fellow divers and naturalists to identify what they see in our beautiful island.
Please join our project and contribute with photos and observations.
The Marine Life Project is the umbrella project for the most specific species lists (e.g. fish, sea slugs, corals, etc.).
Thank you for your contribution!

Trial suppression of juvenile tree weeds

Trial suppression of juvenile tree weeds by partial breaking and bending down of branches has been surprisingly successful since our ad hoc "necessity is the mother of partial-control intervention" in August 2018, when we first became aware of the huge numbers along the roadside and their rapid growth, pushing aside and overshadowing the mahoe, mapou, karamu and other quick-growing natives there.

We have now photographed and marked with orange tape several dozen specimens, with heights of c.30cmH (previously reduced to this height by partial breaking of leading stem) to .3mH.

Most of these trees are not in the defined Trial Site (where such trees were already marked and photographed) so we have advised the Ecocontract Operations Manager, who will communicate to weed control teams that these specimens are not for intervention.

While documenting and marking the privets we intervened similarly on the few Eleagnus that were encountered along the roadside, and cut all the Japanese honeysuckle within reach. It was pleasing to see native trees once again dominant in the roadside vegetation, with some mature trees showing new growth in areas released during the past year. There are still native trees about 10m high whose canopies remain invaded from further down the bank, but as with the tree weed trial, we have been astonished at the effective suppression of weed trees and vines and the growth of released native plants resulting from our ad hoc interventions during survey.

This has encouraged us to continue to spend those few minutes in passing whenever an opportunity arises to save a native tree from imminent destruction by weeds.

The Ten Thousand Tree Mountain Fynbos Challenge

Welcome to the Ten Thousand Tree Mountain Fynbos Challenge.

Our goal is to clear 10 000 trees in a month.

Let us see if we can do it in October 2019.
Simply clear your area, and add an observation for each species that you cleared, adding this project and specifying how many trees you cleared. Pines, Wattles, Hakeas and other alien tree species apply: no matter how big they were when removed (seedlings, juveniles or giants).
Any other information will be welcome, either in the description or notes. Add some photos of your team in action (or recovering afterwards).
