Anthidium florentinum (17-6-08 Zaragoza)
Mating. This species is one of the few insects with a male much bigger than female... usually the biggest sex in insects is the female. In A. florentinum the mating is a bit rude, the male fly slowly, stopping in the air from time to time, and when he see a female, throw itself as a kamikaze, don't leting the female to move, and then start mating during few seconds.
