Food Plant: Populus nigra (Black Poplar)

Mine: Probably univoltine: late summer, but may sometimes be bivoltine

Pupa: Inside the mine

Notes: A long winding white gallery (as shown), starting lower side, shallow and going upper side, broad. The mines may not be upper surface and in some cases may be totally lower surface. There may be several mines in a leaf (as shown). Southern England. Pupation is in the mine, which distinguishes it from A.tremulae. A tremulae has a mine which is always lower surface. Mines identical to A.populicola, with external pupariation, have been bred from this species (B.Warrington 2024.). . Homan (2024) found a mine of A.populi which showwed the typical gallery mine on the underside of a leaf but then swapped to the upper side and mimicked the morpholgy of a mine of A.populicola!
