This impressive critter fluttered onto a blacklit sheet set up for National Moth week at the edge of a mixed hardwood forest at 2000' elevation in the Santa Cruz mountains on the San Francisco Peninsula. At first we (Debbi B., Jan H., Kat G., and I) thought it was an antlion, but that didn't quite fit. Debbi figured out that it was a fishfly. The body size and moniliform antennae seem to point to Neohermes. And a male at that (erect hairs on the antenna beads).

Right? If so, what species? Powell & Hogue place N. filicornis here in the Central Coast Range. Too bad, didn't get a good shot of the end of the abdomen. But otherwise some decent photos (see following).
