When recently at Occoquan Bay National Wildlife Refuge I spotted these two damselflies, which an expert identified as probable Big Bluets (Enallagma durum), I initially thought they were mating. Then I realized that the positions were all wrong and the nibbling on the neck was probably indicative of a literal hunger. Yikes.

As Tina Turner once sang, “What’s love got to do with it?”

At first I thought it was love, but looking closer I realized that Tina Turner was right—what’s love got to do with it. Both the predator and the prey in what appears to be an act of cannibalism look to be Big Bluet damselflies (Enallagma durum), which I spotted this past Sunday at Occoquan Bay National Wildlife Refuge.

The pale coloration of the victim suggests to me that it is newly-emerged, a phase referred to as “teneral.” At this stage of development, dragonflies and damselflies are relatively immobile as their bodies and wings are transforming and are particularly vulnerable.
