    Wood Leopard Moth - (Zeuzera pyrina)

    The bold black spots of the Wood Leopard Moth are unique and attractive, but this moth is an enemy to fruit and decorative trees alike.

    Staff Writer (2/2/2017): The Wood Leopard Moth is a non-native species in North America that was recently seen on the East Coast in the 1870s. In Europe and Asia, it has long been considered a pest to fruit trees like plum, pear, apple as well as decorative trees like ash, oak, elm, willow, and beech. The life cycle of this species includes 2 to 3 years inside of stems feeding off a trees juices before it pupates into the winged adult. Caterpillars leave a reddish frass (feces that resembles sawdust) at the base of the tree trunk that they are feeding on. They siphon the nutrients of the tree, resulting in browning leaves, death of new shoots and damaged branches. The fruit production of infested trees suffers greatly and limbs of the tree either fall off, or are deliberately removed and burned to try to contain the spread of the caterpillars. Chemical pesticides applied to the entire tree as well as entry points on branches also helps control the larvae.

    Adults are active from the beginning of summer to the beginning of autumn.
