in an old leaf, having lost most of its felt cover, it is obvious that no real mine has been made
The young larva makes a short, upper- or lower-surface corridor along the midrib, often continuing for short distance along a side vein. Then the mine continues into a lower-surface tube of silk, covered with much frass, from which the larva causes under-surface window feeding. In white poplars this occurs under the felt cover, causing a pseudo-mine.
Mining larvae in September – November; after hibernation they feed on buds.
