Thread subject: :: angled M-vein in Calyptratae

Posted by John Carr on 27-08-2019 12:59

I read somewhere that curved veins near wingtip can help maneuvering or hovering flight. I assume they make the wingtip stiffer. The course of wing veins evolves slowly. If an ancestor of Oestroidea saw a strong benefit from curved vein M and its descendents didn't care, the bend could be present for no obvious reason.
