Black Quills and Blue Quills

This common name refers to only one genus.

Mayfly Genus Leptophlebia

These are pretty much always called Black Quills and Blue Quills.
Leptophlebia mayflies do not generate superhatches, but their medium-large size and other properties make them a relevant part of the early season.

The information below was mostly discovered in Leptophlebia cupida, the most important species, but it is not known to differ in the others.

Female Leptophlebia (Black Quills and Blue Quills) Mayfly DunFemale Leptophlebia (Black Quills and Blue Quills) Mayfly Dun View 7 PicturesI collected this mayfly after user Al514 tipped me off to the presence of some Leptophlebia mayflies I didn't seem to have yet with his ID request of a male dun. This seems to be of the same species. I also collected a female spinner. Based on that spinner, I can tell that this is either Leptophlebia cupida or Leptophlebia nebulosa, but I can't tell which.

Unfortunately none of the specimens I collected made it through the hot, sunny day very well. So the pictures aren't great, but they're better than nothing.
