Agonopterix kuznetzovi

Agonopterix kuznetzovi is a moth of the family Depressariidae. It is found in Great Britain and Russia.

The wingspan is 15–20 mm. Adults are on wing from July to October and (after overwintering) in spring.[2]

The larvae feed on Serratula tinctoria. They initially mine the leaves of their host plant. The mine has the form of a short, gradually widening, brown, corridor. There is a small, lower-surface hole which is lined with silk found at the beginning of the mine. This hole is used to eject the frass out of the mine. Older larvae vacate their mines and live freely in a spinning under a leaf. Finally, they spin a leaf into a pod.[3] Larvae can be found from late May to June. They are pale green with a black head.
