    See if you can identify this beautiful adult caddisfly. Will be looking for family, genus, and species. As before, each identification attempt will receive a prompt and respectful response.

    Okay, I perhaps it's time for some clues. Although this caddisfly is not well-known, it has been reported from WA, inhabits stillwaters, and emerges in October. It is of the same family (and closely resembles) a caddisfly which is well-known, also emerges in October, but inhabits rivers rather than stillwaters.

    Hi Patrick,

    It is not a Traveling (also called Traveler) Sedge, as they have stouter antennae. However, I do appreciate your having the courage to take a stab at it.

    Hi McNasty,

    Giant Orange Sedge is one of the common names for the (quite similar) river-inhabiting caddisfly mentioned in post #2 of this thread. However, its stillwater-inhabiting counterpart does not have any common name of which I am aware.

    Ah, thanks for the clarification, Derek. Although I wouldn't expect a Summer Flier Sedge to still be around in October, Limnephilus externus looks like this:
