Locust boring beetle, Megacyllene robinae - Megacyllene caryae
Eden, Rockingham County, North Carolina, USA
March 11, 2007
Size: 1"
Identified by Eric http://community.webtv.net/bugeric/BugEric
author, "Kaufman Field Guide to Insects of North America". "You must have firewood in the house (I do), and that is where they are emerging from. Hickory borers are well-known for this phenomenon. They pose no threat whatsoever." He stated that in the fall, a nearly identical species, the locust borer, M. robinae, is abundant on goldenrod flowers.

This is then Megacyllene cary
This is then Megacyllene caryae, not robinae, if this was seen in March.

I agree
Megacyllene caryae is correct, The narrow elytral bands alternating yellow and white, the reddish legs, and the early flight time are all diagnostic.
