YouTube video by Kim Wilde Kim Wilde - Kids in America (Official Music Video)

OK, I love this song, but there is some sketchy geography in the lyrics that always catches my ear - maybe Kim Wilde hadn't spent much time in the US, because "East California" really isn't a thing... :)

"New York to East California
There's a new wave coming, I warn ya"

One more beauty for #flyweek : a bee fly I photographed in the Mojave Desert a couple of years ago which was kindly identified as Poecilanthrax californicus by York Niu.

Very excited about a new paper from Natalia von Ellenrieder on a new species of whitefly in CA! Especially because "A key to all species of whiteflies with black puparia known to occur on oaks in North America is provided". :) www.researchgate.net/publication/...

Posting this rather colorful and snazzy-looking gall midge (Cecidomyiidae) I found in the Mojave Desert recently for #flyweek !

A surprising amount of flies migrate! Fascinating stuff for fly lovers everywhere. ๐Ÿชฐ๐Ÿ’•

A "long-horned" bee, possibly in the genus Eucera, found at Carrizo Plain NM in California today. #bees #pollinators

Fossombronia from the Oakland hills. By far one of the best looking liverworts around. If springtails go to raves in the Oakland hills this is definitely the disco balls they dance beneath. #oakalnd #Fossombronia #liverworts #nature

Wtf! A bazillion species to choose from and they picked something from another family?

Phase contrast photomicrograph I took recently of a "fingerprint"-like pattern on the integument of a snout mite (Bdellidae) - a few hairs and hair sockets are visible. Apparently the precise pattern is useful for species identification.

Possibly my new favorite moss - Hedwigia (maybe H. detonsa) growing on the north side of a large rock outcrop in San Luis Obispo County, California.

I was really excited to be able to key out this tiny (395 micron) mesostig mite I found in coast redwood leaf litter all the way to species - not an easy task for most mites. Meet Cosmozercon setosus, slide mounted in Hoyer's medium. ๐Ÿคฉ

Another tiny but fearsome predatory soil mite - Labidostomma sp. recovered from coast redwood leaf litter in northern California and mounted on a microscope slide. Check out the massive jaws (chelicerae) and the ornate ornamentation on the cuticle! :)

I found this mound of scat (?) on a log in northwestern CA recently and it appears to have become a food source for a cool-looking fungus in the family Phycomycetaceae? Not able to check with microscopy and have never seen this before, so corrections welcome if I've got this wrong! ๐Ÿ˜

I photographed this Condylostylus sp. long-legged fly at a little city park in Fresno County, California earlier this year. It was only a few millimeters long. This family of predatory flies is diverse and can be photogenic because of their metallic sheen. #diptera #entomology #flies

A slide mounted cunaxid mite, Cunaxa capreolus, collected from leaf litter in northern California recently. Only 0.5 mm long, but sure to strike fear into the hearts of the litter springtails it might have encountered.
