Depressariidae

32.015 Blackneck Buff Agonopterix subpropinquella (Stainton, 1849)

Common

Similar species:

Forewing: 7.5 to 10.5mm

Habitats: Dry grassland, downland, wasteland and disused quarries.

Habits: The moth comes to light.

Foodplant: The young larva mines a short full depth corridor on Common Knapweed, Greater Knapweed or Saw-wort which it soon leaves to live in a silk tube in a rolled leaf. When feeding on Creeping Thistle and Spear Thistle the mine becomes a blotch. It leaves the mine at a late stage to continue 'window feeding' from a web under a leaf. It is also known to feed on Greater Burdock and probably other species of thistle. It pupates in a cocoon in the earth or in leaf litter.
