Least Black Arches, and a "fluffy" micro

Only 22 moths attracted to the garden moth trap last night, but quite a variety with 16 different species. New for the year were Poplar Hawk-moth, Marbled Minor agg., Pale Prominent, Small Waved Umber, Treble Lines, Light Brocade and Rustic Shoulder-knot, while a completely new moth for my garden list was Least Black Arches, shown below.

There was also a tiny micro, fw about 3.5mm, which has a sort of fluffy appearance - see photo below. Any suggestions as to what it is?

Finally, the moth below (found indoors, fw 5mm) I think is Mompha subbistrigella.

  1. re the middle one - the closest I was thinking would be Brymorpha domestica? But that isn't furry. Do you have a top view?

  2. "Fluffy" is the giveaway: Lepidoptera = scale-winged, Trichoptera = hair- winged. You are not the first to be fooled by a micro-caddis!

  3. Thanks Dave, caught out again! I can usually recognise the regular caddisflies, but the micro versions always fool me once or twice a year.
