Small Dusty Wave

A fairly frequently recorded moth, but with a patchy distribution, fairly common in the south and west of the county and also in the north, but rare in much of the centre and east.&nbsp; Double-brooded in Somerset.

Silky Wave

A very rare species, found only in the Avon Gorge area and two parts of Wales. Occupies limestone cliffs and downs with the larval foodplant, Common Rock-rose.

Dwarf Cream Wave

A local species, common around Minehead, Taunton and the Parrett estuary north to Weston-super-Mare.&nbsp; Quite scarce in the east of the county, and seems to have disappeared from the Yeovil/Crewkerne area where it used to be frequently recorded.&nbsp; Numbers of the moth collapsed following the poor summer of 2007 and have never fully recovered.
