Species Account

Sutton & Beaumont, 1989: Thinly distributed and generally uncommon, recorded from vice-counties 61 to 64.

Beaumont, 2002:
VC65. Low Row, July and August 1995, frequent, det. HEB (TMW). NEW VICE-COUNTY RECORD.

2013 (CHF): One of the few all-white species, only likely to be confused with the slightly larger Elachista argentella but easily recognised because of the large white eyecaps at the base of the antennae. The name salaciella is nothing to do with Salix but is from salax meaning lustful - perhaps the first ones described were "in-cop". The food plant is probably Sheep's sorrel. It seems to have become either more common or better recognised in recent years and is widespread across the county.
