Well, you just tough something new to a biologist ! Evolution always amazes me, that's one of the reasons that I love whales... they are so different from other mammals, how their structure diverged from the regular guys that walk! In this case , Oh my gosh! Diptera means two wings! that's the thing that differentiates flies from the rest of the insects that usually has two pairs of wings! This fly doesn't have wings! hahahaha it is almost an arachnid with 3 pairs of legs instead of 4 lol
A fly that doesn't fly! If that impressed you, google for world's tiniest insect. It's a parasitic wasp and it's smaller then many one celled organisms! Mind blowing
