Firefly Trying To Mate With My Outside Window.

First let it be known there are about 170 species of fireflies not only that but each individual male firefly has its own light pattern ,and that is use to find a female that reponses back with the same pattern sometimes the firefly will mistake his  reflection in a window for his mate due to matching light patterns even tough both were done at exactly at the same time.

Of course when a male firefly heads for the female they'll mate. However, if the female realizes it is not a firefly from her own species the male firefly gets ate.

The fireflies flying in the air are usually the males. The females stay usually on the ground in the grass, on top of leaves or other bottom plants.

The male firefly above has a repeating light pattern of three shorts and two longs and mistakes his reflection of the window for his mate since his reflection "reponsed" with three shorts and two longs also.
