Moved from Mayflies.

Ephemerella invaria
The physical characteristics like head shape, eye spread and pointed vertex, pronotum, and thorax shape are well within the genus of Ephemerella and the white articulated tails say very likely invaria. The abdominal spirical folds align with Ephemerella as well. Subvaria is darker and gone for the season up here, and it is to light for the form rotunda.

Jean do you see these often like this sample and do you have more views you can load.


Ephemerella invaria
