FOY Tree Swallow yesterday! (this pic #FromTheArchives!)
Stoneflies watch out!
Today I actually have a few windows open (i.e. the few that have screens...don't get me started on the cost of custom size screens...)
Back to rain come Sat - but we'll enjoy this while it lasts! #birds #becurious

When you're Lord of the Stoneflies (Pteronarcys californica) you can perch on Poison Oak (Toxicodendron diversilobum) if you damn well please!

With females topping out at 3" Salmonflies are the largest NA stoneflies! (skeet deleted/corrected/reskeeted) #inverts

PLECOPTERA (stoneflies): flat insect with straight body. 2 filaments from adult rear end. wings flat over back at rest. hindwings much broader at base than forewings. long, thin antennae.
nymphs exclusively aquatic with 2 filaments from rear end. gill placement variable. resemble adults.

Rapid adaptation is thought to be critical for the survival of species under global change, but our understanding of human-induced evolution in the wild remains limited. We show that widespread defore...

Winter stoneflies (Plecoptera: Taeniopterygidae) don’t need warm, sunny days to be active. These cold-adapted insects are at their peak from January to April. Their aquatic naiads thrive in cold, oxygen-rich winter water before molting into flying adults to mate. Blissfield Michigan, 27 Feb 2016.

Spotted what I think are Black Stoneflies (Austroperla cyrene) at the Rob Roy Glacier Track, Wanaka, New Zealand on 1 Jan 2026. They were moving on rocks near a stream.
