Понеділок Moth

В цей понеділок я відступу від звичайної Arctiinae щось зовсім інше – microlep! Це Nepticulidae, Stigmella diffasciae, і він вимірює в на колосальні 6 мм. Я не можу взяти кредит на поширенні цієї молі – all of the nepticulids I have photographed are from the California Academy of Sciences and spread by Dave Wagner while he was here for a postdoctorate position.

The caterpillars mine the upper-side of the leaves of Ceanothus and are known only from the foothills of the Sierra Nevada in California. If you’re so inclined the revision of the North American species of the genus is freely available here (.PDF).

  • I could almost get interested in microleps, just for the challenge of getting good at spreading them.

    It’s interestingthe scales don’t seem to have gotten tiny in proportion to the moth.

  • Так, I’m guessing this is an example of a flying bug SO SMALL that the physics it deals with are different, so the wings are different than they would be on a comparable-but-much-larger moth? Or is that not quite happening at this scale? I can’t remember what high relative viscosity of air does to wings.

    HmNow I’m thinking the wings start to look more like oars on super small fliers vs. feathery like this?

    Так, how’s THAT for a wandering comment. =)

    • I think you are correct, that once you get this small the moth ends upswimmingthrough the air more than flying. Many micros have increased their wing surface using long scales instead of a solid surface, I bet the greater surface area helps with flight. I do know there are some impressive wasps that are much smaller than this moth and have even less wing-like wings! I don’t know the physics at all though
