While looking for the milkweed bugs in some fringed twinevine, I happened across an assassin bug apparently enjoying a little lunch.
Here's a tigher crop, showing the little aphid or larva it is eating.
I thought it would be pretty simple to find an assassin bug on Bugguide.net but I really had a heck of a time. Fortunately, there are many bug experts who know how to figure that out. It is a Zelus renardii.
