About Prionoxystus robiniae Peck, 1818
Prionoxystus robiniae, commonly known as the carpenterworm moth or locust borer, is a moth species that belongs to the family Cossidae. It was first formally described by Peck in 1818. This species is distributed in southern Canada and most of the United States. Its wingspan measures between 43 to 85 millimeters, which equals 1.7 to 3.3 inches. Adult moths are active on the wing from May to July, with the activity period varying based on the location the moth inhabits. The larvae feed on the wood of locust, oak, chestnut, poplar, willow, maple and ash trees. This species is classified as a pest, because the tunnels larvae make inside wood reduce the commercial value of hardwood lumber.
