What's That Bug? does not endorse extermination

Subject: Orange Bug on Tulip Poplar

I noticed recently that some of the large branches on a 150+ year old tulip poplar have been debarked. This is in northern virginia.
Yesterday, i found a number of ant-like insects on the tree. They have 6 legs and seem to have two defined body segments.
If you look at the insect from tail to head, it has a bright orange behind, a black horizontal stripe, and an orange top to the main body. The head is reddish orange. The legs are black.
I’d like to find out what kind of insect this is. I’ve never seen anything like it. The closest thing i can find is a cow killer, but those are furry. This is smoothe with no real fur.
Thanks for your help.

Checkered Beetle

Hi John,
This little beauty is a Checkered Beetle, possibly
Enoclerus ichneumoneus Checkered Beetles are not damaging your tree, and they are most likely feeding on insects that might be negatively impacting the health of the tree.  According to BugGuide:  “predaceous on other insects, larvae mostly on wood- and cone-borers; some adults feed on pollen; a few species are scavengers.”
