RBD #281 Phainopeple (Female)

RBD #280 Bladderpod spiderflower

Wikipedia says Peritoma arborea gives off a foul smell to discourage insects but this honeybee doesn't seem to mind. I didn't notice it walking by.

RBD #278 Joshua tree
RBD #278 Joshua tree

Playing with the late afternoon light. You can see the Joshua trees arrayed in the distance. The 5+ inches of rain every year is enough to support vegetation, though there is a lot of bare ground between the plants.

RBD #275 Joshua tree
RBD #275 Joshua tree

The Joshua trees are flowering. This happens after a bit of rain and a bit of frost, so my timing was just right. The latin (Yucca brevifolia) makes it clear that this is an overgrown yucca; they branch when the flower falls off. About a quarter of the yucca species are tree-like, so not uncommon. Brevifolia means "small-leaved".

RBD #274 Woolly darkling beetle
RBD #274 Woolly darkling beetle

A most excellent stinkbug from San Dimas, the woolly darkling beetle has more of a scrub brush than a mop top.

Looking through Bug Guide there are species all over Coleoptera that have visible hair. This seems like a strange feature to suddenly appear, but there is an evolutionary path: According to Parks Canada, "Tiny hairs called “setae” on the outside of the exoskeleton help improve the beetle’s perception of touch and sound."[1] Expanding an existing structure so that it is visible is not so hard.

Across the phylum, "Arthropods also have a wide range of chemical and mechanical sensors, mostly based on modifications of the many bristles known as setae that project through their cuticles."[2] If bees and spiders can be fuzzy, why not beetles?

RBD #269 Orange mint moth

Another obvious name, an orange mint moth (Pyrausta orphisalis) on calamint (Clinopodium nepeta). The generic name Pyrausta comes from a mythical insect-sized dragon that lives in fire. No idea about orphisalis.

RBD #268 Pale green assassin bug

When you are lying in wait on a leaf you want to wear green rather than black. I like the latin: Zelus luridus. Luridly zealous? Bonus: it's a volunteer biocontrol agent.

RBD #267 Broad-handed leafcutter
RBD #267 Broad-handed leafcutter

Broad-handed leafcutter (Megachile latimanus) with sachem (Atalopedes campestris) on NY ironweed (Vernonia noveboracensis).

There are two dozen leafcutter bee species in Maryland, and I'm not certain I've got the right species label. Regardless, I do like the name. Wiktionary claims Megachile comes from Greek for "big lips". The common name (leafcutter) is because many of them line their burrows with bits of leaf which they cut from plants.

RBD #258 Cat ice

Lots of things going on here. The thin cloudy sheet is called "cat ice". It's so thin it can't even hold a cat? Then there are the ribs underneath. Why are they growing down in the water, and only in some parts? On the surface there On the top we see crystal clear versions of the same thing. The ice surface is covered in fractal crystals like you see on a window pane on a really cold morning. Thawing and refreezing?
