Hesperoperla pacifica (Golden Stone) Stonefly AdultHesperoperla pacifica (Golden Stone) Stonefly Adult View 14 PicturesI collected this specimen as a nymph and had it in line to be photographed, but it emerged inside my holding container before I got the chance. However, I was able to get some interesting photos of the very freshly-emerged adult that really demonstrate how strikingly colors can change within a few short hours after emergence. The before-and-after pictures are combined here under a single specimen since they portray the same individual at different times within the same stage.

Based on the identification of another specimen from the same date/site, I'm calling this Hesperoperla pacifica.

Kogotus nonus Stonefly NymphKogotus nonus Stonefly Nymph View 9 PicturesAlthough Kogotus and Rickeri nymphs may be difficult or impossible to tell apart, I captured an adult Kogotus nonus specimen in the air on the same day as several of these nymphs, and they are likely the same species.
