Stalk-eye Flies (Teleopsis sp.) mating

I was lucky enough to find and observe a mating pair recently ^_^


Stalk-eye Flies, as the name suggest, have very long eye-stalks (yes, those are the eyes on the far left and right :p).


The males (on top) tend to have much longer eye stalks, which acts as a prerequisite to "tackle" the females (bottom).


Males and females tend to rub their forelegs together (also in my Flickr account), which I suspect it to be a mode for stridulation- calling out for a mate.


When a pair of male and female are close together, the male will bend its body low while using its forelegs to continuously tap the surface of the leaf as a sign for mating.


When mating, the male steps on top of the female. The forelegs of the male are put on the "V-shaped" abdominal spines of the female (so that's what its for lol :p)


PS: These flies are a nightmare to photograph up-close due to their very weird body shape!
