Unknown Moth - Acrolophus arcanella

Unknown Moth - Acrolophus arcanella
Beachwood, Ocean County, New Jersey, USA
July 4, 2012

Moved from Tubeworm Moths.

Arcanella is the only species in NJ that is this robust and has the palps both very short and upturned like this. In popeanella, plumifrontella, and propinqua, the male palps are large and upturned, and the female palps point straight forward. This makes arcanella the easiest Acrolophus to ID in the northeast, even if the wings are very worn.

Moved from ID Request.

Definitely an Acrolophus (Acrolophidae), female individual (as diagnosed by the not-overly-long labial palpi, which in male moths of this genus curve up and over the dorsum of the thorax). Sight ID to species is sometimes (as in this case) rendered difficult by the fact that several of the Acrolophus spp. are quite variable in appearance.
