Ameletus (Brown Duns) Mayfly NymphAmeletus (Brown Duns) Mayfly Nymph View 2 PicturesThese two exuviae are my sad little consolation prize after collecting a couple of really cool, large, mature mayfly nymphs I didn't recognize from a tiny, probably fishless, spring-fed tributary of a slightly less tiny trout stream. I saw the nymphs in the kicknet samples and carefully transferred each one to my holding cooler before going to collect more samples. When I got home, I carefully went through the whole sample and couldn't find either one of them. Getting worried, I did it again and even more carefully. This time, I found both exuviae. By process of elimination, pretty much the only possibility is that both of them hatched out of my cooler and flew away during the 10 minutes or so that I had the lid off to collect more samples.

I was really excited about them for the whole three-hour drive home and seriously bummed that they disappeared. In the field I thought they might be one of the families of swimmer nymphs I don't have yet, like Ametropodidae, but keying the exuviae takes me to Ameletus, so at least I didn't miss some great rarity. Still, they were much larger and darker than any other Ameletus I've collected and probably a species I don't have yet.

Female Paraleptophlebia (Blue Quills and Mahogany Duns) Mayfly SpinnerFemale Paraleptophlebia (Blue Quills and Mahogany Duns) Mayfly Spinner View 1 PicturesThis female is probably P. heteronea or P. memorialis since these are the two species collected during the last two weeks. It is interesting that the females are this very dark brown color while the males are lighter in color.
