Large Western Speckle-wing (Callibaetis californicus)


Arthropoda > Insecta > Ephemeroptera > Baetidae


Recorded throughout California through much of the year (excluding winter). In Southern California the majority of records come from moderately low elevation (under 2000 feet) localities southwest of the transverse ranges, with scattered desert records including Zzyzx Spring and Palm Desert. The species has also been recorded from Santa Cruz Island. Note in particular the unmarked abdomen of the male compared to C. pictus.
