Distribution and Abundance: Local.

Primary Habitat: Parkland.

Flight Period: Single brooded from May to July.

Localities: Yardley Chase, Wicksteed’s Park, Denford and Helpston.

Observations: Although rows of mature poplars in parkland seem to be the favoured habitat for the moth, larval mines can also be found low down in the boles of isolated trees in a variety of more open situations. One way of recording the moth is to examine poplars early in the morning where there are signs of larval activity. The newly emerged moths can sometimes be found at rest on the tree trunks.

L.O.N.: Thrapston, Castle Ashby, Yardley Chase. Some poplar trees are riddled by the larvae, but it is not easy to obtain the perfect insect.

First Record: 1858, Green.
