Food Plant: Populus alba (White Poplar), Populus canescens (Grey Poplar)

Egg: Underside of leaf

Mine: July, September-October

Notes: An underside mine, with few creases and causing little leaf distortion. Some mottling of the upper leaf surface may be caused. The cremaster is smooth and rounded, with tiny spines (as shown). The central pair are close together, which distinguishes it from P.sagitella, which has evenly speced spines.
