I got up around 6:00 this morning so I could go out to the William Pond Park by 6:30 am. I wanted to go checkout the Reverend Mother tree again before it got too sunny and hot outside. I was going to go out with my friend Roxanne, but she had family stuff to tend to, so I went out by myself. It was so smokey outside it was tough to stay out and walk in it. The sun was “red”, and its reflection on the river looked like flaming blood. Creepy! Current PM2.5 AQI levels in the area have reached: 170 AQI (Unhealthy). Because of the smoke cover, the temperature never got above 88° today, and there was a bit of a breeze. The breeze brought more smoke in, but at least the air was moving.

Because of the smoke, the Sacramento Zoo has been closing its doors early; and because of the proximity of wildfires, the Sacramento National Wildlife Refuge has closed its auto tour route so it can be used by fire fighters for staging their equipment.

At the park, I was pretty much just looking for galls today, so didn’t pay attention to much of anything else. On the Valley Oak trees nearest the parking lot, I found lots and lots of Red Cone galls, Oak Apples, and Spiney Turbans. I also found quite a few Round galls (with their lumpy bumpy surface) on those trees; my first sighting of the season.

The Reverend Mother tree still doesn’t have all the galls she normally has, but I was able to find more Red Cones and Spiney Turbans, along with Fuzzy galls, Convoluted galls, and Yellow Wig galls. I haven’t seen any Club galls, Rosette galls or Disc galls on her yet… There were, however, LOTS of Flat-Topped Honeydew Galls exuding their honeydew. I didn’t see a lot of ants tending to them, but I did see a lot of wasps.

In fact, there seemed to be wasps everywhere. I found them on the lawns, drinking water from the grass (the sprinklers had been on just before I got there), and around the trash cans and remains of what I think was a fish on the ground. It was so deteriorated that it had gone black so it was hard to identify what part of the fish it might have been. In another spot, I found a pair of wasps struggling with a dried leaf; they almost looked like they were in a tug-o-war over it. I wondered if they were masticating it to make wet papery mulch for a nest somewhere nearby. I couldn’t get near enough with my camera to be sure. Here’s a video snippet: https://youtu.be/K0QLZPS5LtI

On the live oaks I still haven’t found any of spiney ball galls of the Live Oak Gall Wasp, Summer Generation. They seem really late to me. I found a few Pumpkin galls and some Two-Horned galls, but the stand-out on the live oaks was the number of acorns affected by Drippy Nut, Brenneria quercina, Lonsdalea quercina, a bacterium that infects wounds in oak tissue/acorns. Lots of dark acorns, lots of “foaming” ones, and one that looked like it hadn’t been fertilized yet, so it was just a “female flower”; nothing was left attached to the cap buy a thin, white, skeletal-looking wick. So weird.

Here are the photos from today: https://www.flickr.com/photos/mkhnaturalist/albums/72157719731284702

The water in the river is still really low right now; you can walk across it in places. At one spot near the river bank, I saw a Red-Shouldered Hawk in a tree, a Black Phoebe and some Spotted Sandpipers on the rocks, some Mallards in the water, and a Turkey Vulture on the opposite bank. They all pretty much ignored each other. A trio of Belted Kingfishers flew over a couple of times, chattering to one another, but they didn’t land anywhere near me so… no photos of them. I DID see the hawk later on in another tree being beaten up by some Northern Mockingbirds who wanted him to move along.

I also found an Assassin Bug nymph on some of the rushes by the water, and on a Coyote Brush bush, I found some more Lace Bugs. Some of the lace bugs were tannish-brown while others were pure white. I don’t know if that meant they were different species, or simply different instars of the same species. On the underside of some of the leaves, I think I saw the eggs covered in “varnish”.

“… Lace bug eggs are found on the lower leaf surface, usually alongside or inserted into a leaf vein. Adult females secrete a varnish-like substance over the eggs that hardens into a scab-like protective covering…”
I just think they are sooooo interesting.

I walked for about 3 hours and then headed home. This was hike #70 in my annual hike challenge.
