This might be the only blue moth I've ever seen, and it was tiny. Attracted to a BioQuip UV light in a park parking lot, coyote brush chaparral and grassland, with nearby oak/madrone hardwood forest, scattered conifers, dispersed residences.

Moved from Moths. Don Davis said, "Yes I believe this is an eriocraniid, possibly xanthocara. Probably a dissection would be necessary for certainty."

Possible ID?
Perhaps Eriocraniella xanthocara or E. platyptera? The antennae don't look quite right though. I've forwarded this to Don Davis at the Smithsonian to see what he thinks.

other possibilities
I suspect this is one of Powell & Opler's "Primitive Lineages" (p. 33 of their book), maybe Stigmella or Tischeria. I just haven't found any pics of species in those genera that are metallic blue. Thanks for sending this along!

Moved from Tineoidea. I am not entirely convinced this is a Tineid and not one of the more primitive moths families like Micropterigidae or Eriocraniidae. Moved here for a second opinion.
