Anyone knows which is the chemical composition of dipter wings?
The veins are scletorized by chitin, right? and the rest of wing? Is it made by which composition? clarify me, please. Smile And what about halteres?

hello Jorge,

Chitin, as a major component of the arthropode integument, is 'per se' not so hard or 'sclerotized'. Sclerotization happens by addition of some protein (arthropodin), that gets hard when phenolated ('tanning' ), or some carbonate (e.g. in lobsters and such). At articulations etc. where the exoskeleton must be flexible, chitin is also present, but thinner and softer (not or barely sclerotized).

So the wings of insects are not principally different from the rest of the exoskeleton, they are mostly chitin and protein. The veins are derivates of tracheae (breathing tubes), that are necessary for stability and for the inflation (spreading) of the wings after moulting (the wings are literally pumped up).

Hope that befuddles ;-)

p.s. Halteres, in some way, ARE wings ... no special chemistry here.

Hello Paul and Jorge,

thanks for you appreciation. Grin

I forgot to mention: the hardened. phenolated arthropodin is called sclerotin ...

cheers - martin

Hi. Please delete all photos of E. carrapateira I've uploaded. I did not remember that I already had uploaded that species in particular. Except the pallidifacies (this was not present yet). Thank
