Superficially similar to a number of other tortricid moths, resembling a bird-dropping. The moth has been found on the trunks of apple trees and also occasionally comes to light.

The caterpillar overwinters in a small mine in a leaf of Mistletoe, which by late spring when the larva is full-fed has become a pale inflated blister mine. The larva leaves the mine and pupates in a cocoon under bark or amongst lichens on the host tree.
