Stylurus falcatus

La especie de libélula, Stylurus falcatus, se ha encontrado SOLAMENTE en el Lago de Chapala, que se encuentra en los estados de Jalisco y Michoacán.

Mi mentor, @dennispaulson, me escribió sobre esta especie y dijo:
"Kathy, ... El espécimen tipo era del Lago de Chapala, y ahí es donde los encontré comunes (tanto maduros como tenerales) en dos localidades en la orilla del lago en agosto de 1965. Creo que el registro de Michoacán está en el mismo lago, así que en este momento creo que lo sabemos solo por ese lago. El lago está en una forma terrible (lea sobre esto en Wikipedia si no lo sabía), lo que plantea preguntas sobre el estado de la especie. Nunca ha sido evaluado para la Lista Roja, pero ciertamente debería serlo. Si conoce a alguien que vive en las tierras altas de Jalisco, puede pedirle que intente encontrarlo, ya que podría ser un verdadero problema ".

Estoy trabajando en la creación de una página web / PDF sobre las especies encontradas en Jalisco. Aquí hay una página de él (aunque no a escala). SI PUEDE ENCONTRAR EL TIEMPO PARA BUSCAR ESTA ESPECIE Y PUBLICARLO EN INATURALIST, ¡por favor hágalo!

Stylurus falcatus

The dragonfly species, Stylurus falcatus, has been found ONLY on Lago de Chapala which is in the states of Jalisco and Michoacán.

My mentor, @dennispaulson, has written to me about this species and said,
"Kathy, ....The type specimen was from Lago de Chapala, and that’s where I found them common (both matures and tenerals) at two localities on the lake shore in August 1965. I think the record from Michoacan is on the same lake, so right now I believe we know it only from that lake. The lake is in terrible shape (read about it in Wikipedia if you didn’t know this), which raises questions about the status of the species. It has never been assessed for the Red List, but it certainly should be. If you know anyone who lives in upland Jalisco, you might ask them to try to find it, as it might be in real trouble."

I am working on creating a webpage/PDF about the species found in Jalisco. Here is a page from it (not to scale though). IF YOU COULD FIND THE TIME TO LOOK FOR THIS SPECIES AND POST IT ON INATURALIST, please do!!

Thank you for reading this and I hope you will try for it.

Maps of Mexican Odonata Species

I had fallen in love with Dragonflies decades ago, and as a teacher, I began sharing about them in 2000. First building a website for California's Odonata and then that evolved into a pocket field guide. After visits to the American Southwest, I realized that the area had a unique fauna and built a website for the dragonflies there which also evolved into a field guide.

When I visited Yelapa, Mexico in 2014 I became aware of the need for an identification guide for the area that would be available to the public and created, first, a website, and then a downloadable printable PDF (free at http://bigsnest.powweb.com/southwestdragonflies/YelapaDragonflies/yelapaFrontPage.html).

Eventually, while making identifications on iNaturalist and on Naturalista in Mexico, I became aware of the need for maps for the species. Dennis Paulson and Enrique Gonzales had compiled a list of species by state and I had been using that, but it was difficult to visualize distribution from the list. With the encouragement of Dennis Paulson, who has served as my mentor in all things Odonate for decades, I have now created maps for the species of Odonates in Mexico. They can be accessed at
http://bigsnest.powweb.com/southwestdragonflies/YelapaDragonflies/Mexico%20Maps2018.html

I hope both visitors to and residents of Mexico will find these maps useful. I am alsohoping to obtain a grant from the Dragonfly Society of the Americas to have my Yelapa/Cabo Corrientes website translated into Spanish so that if can be better used by non-English speakers/readers.

Thank you for your interest!
