Query Damsel Flies mating followed by cannibalism
Hi,
I was photographing these Eastern Forktail Damselflies (July 25th) and after mating the male appeared to be killing and eating the female. The wings actually fell off. I ‘Googled’ the query Damselfly Mating and Cannibalism and came to your site.

Hi Marlene,
We are curious to hear from any experts regarding what we suspect is an unusual phenomenon. Postcoital Cannibalism is not that rare in the world of insects and arthropods since a male sperm donar will also provide a hearty meal for the female who now has the burdon of laying eggs. She needs her nourishment. The role reversal in your Damselfly image would seem to be an anomaly.

Hello, I am a NY Dragonfly and Damselfly surveyor and am responding to the email below. The damselfly was identified as a male but it is in fact a female Eastern Forktail (Ischnura verticalis). While it is not common for a female to eat the male it is not unheard of. Dragonflies and damselflies are frequently seen eating other dragonflies and damselflies.
