Cyclorrhapha

Housefly

After the way flies hatch from their pupae, we divided them into sub-groups, the gap panties ( Orthorrhapha ) and cover Panties ( Cyclorrhapha, cyclo - gr = annular and raphe = seam). The lid panties blow with her ​​forehead bladder ( Ptilinum ) in which they press hemolymph, the cover of their Tönnchenpuppe from. These are the most advanced group of flies, which includes the great bulk of all Diptera species.

They are divided further into the group of Aschiza lacking the forehead bubble (this includes the hoverflies ) and the Schizophora that such well-known with the Calyptratae groups such as the Real Fly ( in the housefly ) that blowflies and the Tachinidae, as well as the very large number of families Acalyptratae, which include a number of small to tiny species. The Calyptratae differ (among others) by the possession of a Calypters ( a wing scale ) of the Acalyptratae.
