Ephemerella tibialis - voucher specimens, in alcohol - Ephemerella tibialis

Healdsburg, Mill Creek Road, Mill Creek, Sonoma County, California, USA
May 12, 2009
Size: 6-9 mm body length

I've included several individuals in this account since color varies considerably depending on the maturity of the nymph. I've noticed this species listed under Serratella tibialis in BugGuide. The species name has been changed to Ephemerella tibialis. See ITIS account. Keyed to genus using Merritt, Cummins and Berg (2008) and keyed to species using Allen and Edmunds' " A Revision of the Genus Ephemerella (Ephemeroptera: Ephemerellidae) VI. The subgenus Serratella in North America". 1963.

I've read that Ephemerella tibialis emerges in late summer/fall

If that is correct, I'm surprised to see such mature nymphs from spring. Could the species ID be incorrect, or perhaps my information on emergence timing is wrong? Any thoughts?

E. tibialis

Bill - If it was only one year, I could have doubts about the time they were found in the creek but I lived on the creek for seven years and they always showed up in May or June. As for the ID being incorrect, its always possible, but I was very careful in trying to get it correct.
