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.

Russia, near S.-Petersburg (Toksovo), on raspberry-bush, 26.08.2007, 18:30-20:30

At first, female alone (and no males nearby):

Steve will love this, by sure!
I wonder why the female uplift its first pair of legs. Maybe "she" is trying to scare the voyeur... Grin

What is known about the pheromones of tephritoid flies? I have seen some pallopterid males collected from traps baited with tortricid (Lepidoptera) pheromones. All males had the aedeagus exposed, so they had clearly died happy Smile But only single flies were in each trap - if the pheromone was a strong attractant, I'd expect to see hundreds as the Palloptera species is common. So the tortricid pheromone must be very weakly attractive to the males at least at long distances. Perhaps it smells a bit like a short-range female pheromone - like, perhaps, the stuff in those paired glands Smile

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
