I'm not familiar with this species, but I've taken another look through all the photos, and this is the best rationale I can come up with--
: Wing venation is wrong; spur pattern is wrong; maxillary palp is wrong. But H. betteni
is about the right size and color.
Not Phryganeidae: Size is wrong (common genera, Phryganea
, typically range from 21-25mm); spur pattern is wrong (usually 2,4,4).
Probably Limnephilidae: Shape and venation of front and hind wings very
similar to drawings of Dicosmoecus
wings; maxillary palp matches configuration of Limnephilid females; spur pattern 1,2,4 matches (usually 1,2-3,4); large setal wart on scutellum matches.
: Size of specimen (13-14mm) is about average for this genus; overall color and pattern seems compatible with other members of this genus I've seen; the pattern of setae and setal warts appears to exactly match a drawing of Limnephilus
; location and habitat seem reasonable (but with 95 species in the genus, it's hard to rule anything
out on that account).
The other reason for suggesting Limnephilus
is a simple process of elimination. It's probably not Frenesia
, based on season (and color). I know Pycnopsyche
well, and it's not either of them. I'm familiar with Dicosmoecus
, and that's not it. Onocosmoecus
are larger; and Ironoquia
is a different shape. Ecclisomyia
, and Chyranda
all have "Western" in their common name.
I know this leaves out quite a few oddball genera, but I'm sticking with Limnephilus
until Litobrancha picks up this thread and tells me what it really is! :)
