On flying insects-6
|[Note Guidelines] Photographer's Note|
|Trying out methods for photography of insects in flight:|
The picture of sitting (not flying) Sympetrum danae shows that the wings are corrugated, divided by veins into small planes or valleys. To my big surprise this corrugation has a function. Scientistst demonstrated that in a windstream tiny whorls of air are forming in valleys between veins that help to form a smooth envelope. When dragonflies sail, the wings are extended and stacked in double-decker fashion. Successful sailing depends on smooth surfaces of the wings.
“As adults, survivorship of dragonflies may be dependent on flight performance during hawking (continuous prey seeking on the wing) or darting, on prey recognition, targeting, interception and capture, on predator evasion and, in some species, on fuel economy and navigation during migration flights” (cit. from R.J. Bomphrey et al. 2016. Flight of the dragonflies and damselflies. Phil. Trans. Roy. Soc. B 371: 20150389.
