Hemiptera Nymphs

Broad-headed bug (Alydidae) nymph on blue bedder.

There have been numerous Hemiptera nymphs in the Dirt Patch lately. I hope some of the adults stick around so I can get more photos. Above is a strange one- the nymph of the broad-headed bug is an ant mimic. It's a very good one, too, at first I thought it was a slightly larger than usual carpenter ant; then I got closer and thought...velvet ant? It's still strangely shaped for an ant...then I clearly saw its proboscis (visible in the photo above), and scrambled inside to get the camera. It moves very much like the larger species of ants do, very quick and alert. A few years ago I photographed an adult broad-headed bug on the work vehicle I was using for that day's field assignment (third below).

 Many Hemiptera nymphs congregate when they are newly hatched through one or two instars (molts). Safety in numbers! Though the bright coloration warns of potential indigestion as well.

As is the case with most stink bugs, this one is a vegetarian
