Synonyms and other taxonomic changes
Prionoxystus macmurtrei (Guérin-Méneville, 1829)
wingspan 45-75 mm
larvae to 57 mm
Adult: forewing mottled gray and blackish with thin black lines crossing the wing at right-angles to the costa; wings are translucent but the translucency is usually not apparent unless the wings are spread against a background of contrasting colors

Larva: pink to white with dark head and thoracic shield
Ontario and Quebec to Florida, west to Texas, north to Minnesota
hardwood forests
adults fly from April to July
larvae bore in wood of ash, maple, and oak, and their tunnels decrease the value of hardwood lumber
Life Cycle
Life cycle takes 2-3 years.
The larvae spend their 1 year in the outer layers of the bark and the 2nd in the sapwood. In the 3rd summer, they bore in the woody part of the tree, making a labyrinth of crossing and recrossing tunnels.(1)
Overwinter as pupa in the tunnel.(1)
