Small Minnow Mayfly - Callibaetis californicus - Female
Palm Springs, Riverside County, California, USA
June 29, 2010
Size: 7 mm

Moved from Callibaetis.

Lloyd Gonzales comment:
This is probably Callibaetis californicus. The dark posterior bands on the ends of the femora (best seen on the right hind femur) and the dark bases of the cerci should help to distinguish this species from similar CA species like C. fluctuans and C. montanus.

Thanks for getting an ID for this mayfly.
