I headed over to the Effie Yeaw Nature Preserve for a walk. It was a gorgeous 62° when I got there around 6:30 am and was up to 77° by the time I left.
I saw mostly birds and squirrels today. Not too many deer and only one fawn at a distance. But the weather was so lovely, I didn’t mind. I’m seeing a lot of fledglings right now, and a lot of adult birds in the middle of massive molts, so everyone looks “messy” … sort of like humans in the summer. Everybody’s on vacation and scruffy looking. Hah!

I saw Acorn Woodpeckers, a pair of Downy Woodpeckers, Black Phoebes, several California Scrub Jays, a Purple Finch and others. But the best photos I got were of some young Red-Shouldered Hawks. One flew down into a tree right next to the nature center, and another flew into a tree by the frog pond. Got LOTS of photos of them.
I also came across a lot of galls and more of those tiny ridged structured Roxanne and I have been seeing all over the place. Someone on iNaturalist said the structures were some kind of scale bug, but I dismissed that suggestion because it didn’t have any of the characteristics of any scale bugs I’ve ever seen. Anyway, I’ve been looking and looking for more clues over the past several months and… finally found them! They are the cocoons of the Ribbed Cocoon-Maker Moth, Bucculatrix albertiella. The cocoons are white when they’re new and turn dirty as they age. They have very distinctive ridges and are surrounded by a “fence” of fine white hairs. I took a couple of samples and will look at them under a microscope (as soon as it’s delivered).
I also found and was able to identify damage done by the Leaf Blotch Miner Moth (possibly Acrocercops affinis) on the leaf of an Interior Live Oak. The moth’s larvae “mine” tunnels through the surface layers of the leaves, and where a lot of the corridors come together, they form large “epidermal blotches” that look like papery caverns on the leaves.
There were a lot of Praying Mantis nymphs among the Showy Milkweed by the nature center. Although they’re still young, they’ve all got those killer spines on their front legs. I got my finger caught by those spines on an adult mantis and I can tell you, it HURTS. They can exert enough pressure to puncture your skin and draw blood… But some cools facts about these critters:
o They can swivel that head 180 degrees.
o Along with those two big compound eyes, they have three simple eyes located in between the larger ones on the top of the head.
o This species has a single ear located on the belly… and they can detect ultrasonic sounds.
Nature is so cool!
