Aquatic Larva - Ephemerella invaria

Aquatic Larva - Ephemerella invaria
Groton, Caledonia County, Vermont, USA
May 2, 2006
Size: 9mm

Ephemerellidae: Ephemerella invaria

Spiny Crawler Mayfly
The gills were in 2 rows dorsally on either side of the abdomen, not on the sides like most of the others.
