SWAMMERDAMIA PYRELLA (Villers) 
Tinea pyrella ViLLers, Caroli Linnaei Entomologia, Faunae Suecicae descrip- 
tionibus aucta, vol. 2, p. 515, 1789. 
In the course of making identifications of moths from Washington 
State, the study of the genitalia of a pair of Microlepidoptera from 
Bellingham proved them to be the European Swammerdamia pyrella 
(Villers), not previously recorded from North America. These 
moths were collected August 13, 1982, by the author. 
The larva feeds on the leaves of apple and prune.

Before me is a series of four moths of this species collected at 
Bellingham (3-8-IV-1928, J. F. G. Clarke No. 3709-12) at light. 
Although these were collected many years ago, it has become pos- 
sible to identify them only recently and to record the presence of 
this European species in North America for the first time. When 
the above specimens were collected, the species was abundant at 
light. I have not seen it since.
