Species Account

Sutton & Beaumont, 1989: Local and uncommon.

Argus 47, 2001-04:
VC63. Potteric Carr NR, 16.5.2004 (RIH). NEW VICE-COUNTY RECORD.

2013 (CHF): This species is either very local in the county or unrecognised. The mines on Bird's foot trefoil and related species are distinctive but the larvae mine early in June to August and the affected leaflet falls to the ground when the larva vacates it. Most mines are in the terminal leaflet. The egg is laid on the underside of the leaf. The mine begins as a long corridor with a very broad, green frass line. This corridor suddenly widens into a broad blotch, that in the end may occupy almost an entire leaflet. The blotch generally begins in the leaf base, and it is here that most frass is concentrated. Shortly before pupation the larva leaves its mine through an exit slit in the lower epidermis.
