917 Scythris empetrella Karsholt & Nielsen, 1976Wingspan c. 9mm.
This rare and local species is currently known only from a few
localities in Dorset, although it was found in neighbouring
counties and there are also odd unconfirmed records from further
north, including one in Scotland. It inhabits sandy heaths,
where the diurnal moths hop around amongst the heather, rather
than taking flight. Adults are at large in June and July. The
larva feeds on heather (Calluna) or heath (Erica), forming a
silken tube combined with grains of sand near the base of the
foodplant, and extending into the sand.
