Red Piercer

Lathronympha strigana is a medium-sized moth with a wingspan of 14–18 mm. The basic color of the wings is light reddish brown. The forewings have a few light lines at the wing tip and two silver cross bars in the outer rear section. Adults are on wing from June to July, sometimes with a second generation in late August or September. The larvae are a little flat, gray green with darker spots and a maroon head. They feed on Hypericum species (St. John's worts).

This species can be found in most of Europe, except in the far north, and in northern Asia.
