Paranthrene dollii (Neumoegen, 1894) - (cottonwood clearwing borer)

This clearwing moth is found in eastern and some central parts of North America, where it breeds in the lower trunk of poplar and willow trees. Especially young trees up to an age of 2 years can be affected and populations can build-up in the rootstocks of nurseries. The damage causes swelling of the trunks and young trees may be killed. The life cycle is completed in 1-2 years and the adults have a wingspan of 3½-4 cm.
