Thread subject: Diptera.info :: Lauxaniidae? - mating (behaviour)

Hello,

here are several photos of yellow flies (Lauxaniidae? Sapromyza?) where females demonstrate small translucent "hornlets" extruding from their abdomens at mating.

BTW, I've noticed that females play very active role in the courtship (no less than males): they start to attract males (showing this interesting pose with "hornlets" and approaching to partners) immediately after male's arrival at the raspberry leaf. Females frequently raise their forelegs at the process - it is another interesting moment of the show.
