Whoops! Two of those spinys were E. invaria

These are both E. invaria -- not E. dorothea.  This one...

is E. dorothea.

Note the tubercles on the posterior edges of terga 4-7 on that large nymph.

E. invaria and E. dorothea are both in our streams at the moment, and it's difficult to tell them apart without a close view.
