Hints and Tips. Parsnip Moth
Micro-moth field tips...Parsnip Moth, Depressaria radiella (was heraclei, was pastinacella!). This is an easy moth to record when you're out and about.
The larva feeds on the seeds of hogweed in summer.
The larva then enters the stem leaving this characteristic hole, top picture. If you open the stem, the vacated pupa should not be too far away from the hole.
There may be more than one larva per stem.
