Assassin bug (Rocconota annulicornis), Newark DE. August 2017.
The consequence of mothing events: the moths are likely to become someone’s lunch.
Assassin bugs are slow-moving predators that prefer to ambush other insects, notably soft-bodied prey like caterpillars, sawflies, and other larvae. As the picture above shows, however, it isn’t picky about consuming larger prey. Its mouthparts are modified like a heavy syringe, able to pierce exoskeleton and siphon fluids from its prey.The articulation in its head is somewhat flexible, allowing the head to swivel around and try to bite things from behind (in case you try to pick it up, for example…).
At least one generation in the Mid-Atlantic, with adults by August.
