Moths in unusual places: Dahlica triquetrella

Amongst several hundred Luffia ferchaultella cases, I found several Dahlica sp. cases on an old concrete wall at Barham Tennis Club, 8.iv.2016.

One of these had recently emerged and although the female was no longer present, the exuviae was still protruding from the case. This is essential if you want to ID these, as characteristics of the exuviae, and in particular the head plate need to be closely examined. Under the microscope this one turned out to be Dahlica triquetrella.

From the database, it looks like only the second occurrence of this species in VC15, previously recorded as cases and adults at a site in Faversham in 1996.
