Red Headed Ash Borer beetles are related to the Long Horned Borer beetles. They mimic wasps in appearance only and harmless to people. They are often confused with wasps when in flight as these beetles can fly - though not as well as wasps. The long back legs sometimes give the beetle the appearance of a cricket, but they are not related. Their yellow stripes on a reddish-black body with red heads give this beetle away quite easily once you've seen them before.

Red Headed Ash Borer larvae will feed on vines or shrubs along with sapwood of your basic oak, hickory and ash trees, but will take on most any other hardwood of downed timber (where the bark still remains) as well. These little critters are unwittingly brought indoors in stacks of firewood that have spent some time seasoning in the outdoors. Once indoors, adult Red Headed Ash Borer Beetles are attracted to light sources.

Red Headed Ash Borer activity is mainly from March to October throughout much of eastern North America. Their reach is reported to be as anywhere east of the Rocky Mountains, though they have been seen in California.
