این دوشنبه من از Arctiinae معمولی برای چیزی کاملاً متفاوت حرکت می کنم – میکرولپ! این یک Nepticulidae است, Stigmella diffasciae, و آن را در بزرگ اندازه گیری می شود 6 میلی متر. من نمی توانم برای گسترش این پروانه اعتبار قائل شوم – همه نپتیکولیدهایی که من از آنها عکس گرفته‌ام متعلق به آکادمی علوم کالیفرنیا هستند و توسط دیو واگنر در زمانی که او برای پست دکترا اینجا بود منتشر شده‌اند..
کاترپیلارها قسمت بالایی برگهای آن را استخراج می کنند سیانوتوس و تنها از دامنه های سیرا نوادا در کالیفرنیا شناخته شده اند. اگر اینقدر تمایل دارید، تجدید نظر در گونه آمریکای شمالی این جنس آزادانه است در اینجا موجود است (.مشاهده در قالب PDF).
Stigmella diffasciae (Nepticulidae)
I could almost get interested in microleps, just for the challenge of getting good at spreading them.
It’s interesting – the scales don’t seem to have gotten tiny in proportion to the moth.
I like the sound of that! You did notice one of the amazing characters of this family, their scales seem to have remained normal size. Those orange tufts on the head are also huge scale eye-caps that nearly cover the entire eye.
پس, 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.
Hm… Now I’m thinking the wings start to look more like oars on super small fliers vs. feathery like this?
پس, how’s THAT for a wandering comment. =)
I think you are correct, that once you get this small the moth ends up “swimming” through 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…
