Helianthemum nummularium (common rock-rose), see plant distribution map.
In Europe also reported on Fumana procumbens.
Feeding signs may not be obvious as the larva feeds inside the seed capsule.
Finding the Moth

Vine (via a note written by E. R. Bankes) that it ......'is on the wing, with heavy flight, from 7pm to 8.30pm on calm and hot evenings'.
A distinctive species with large tufted labial palps and forewings a pale yellowish-ochreous with reddish brown spotting and markings around the edge (see Natural History Museum, Cockayne collection website).
