Double Kidney Ipimorpha retusa
Wingspan 26-32 mm.
Locally distributed in the south and west of England and Wales, this species resembles the more widespread Olive (I. subtusa), which however has divergent cross-lines, which are roughly parallel in the present species.
It is on the wing from July to September, and can be attracted to both light and sugar.
The species frequents damp marshy places, and feeds on sallow (Salix), the larvae spinning together the shoots.
