Plant-Insect Interaction: Horned squash bug on yellow straightneck squash

When looking at some yellow straightneck squash plants (Cucurbita pepo, Cucurbitaceae) in a Michigan greenhouse the other day, I found a bunch of these horned squash bugs (Anasa armigera, Coreidae).  If you zoom in on the head, you can see why they’re called horned squash bugs:  they have two prominent spikes next to their antennae.

I had also found a few striped cucumber beetles on these plants, but there were far more squash bugs.  Like the beetles, these bugs are common and destructive pests of plants in the family Cucurbitaceae (squash, melons, cucumbers, and pumpkins).  A related squash bug (Anasa tristis) is an even more well-known and destructive pest of these plants.
