Ectoedemia louisella

Can you become a moth detective and help us improve our knowledge of an uncommon(?) species? More...

The larvae of the Maple-seed Pigmy Moth, Ectoedemia louisella, cause mines in the seeds (samaras) of Field Maple, Acer campestre, forming an irregular gallery commencing in the wing and concluding in the seed itself. We have very few records for this species and the ones we have are quite scattered - but it may not be uncommon. The adult moth is difficult to identify but once seen, the mines are distinctive, although you will need to look very closely at the ripening seeds of Field Maple. 

If you want to accept the challenge, go out and find some Field Maples right now!
