Female Paraleptophlebia (Blue Quills and Mahogany Duns) Mayfly DunFemale Paraleptophlebia (Blue Quills and Mahogany Duns) Mayfly Dun View 5 PicturesI hadn't seen an intact adult mayfly to catch all day, when suddenly I saw this Paraleptophlebia dun flying six inches in front of my face and nabbed it with my hand without even thinking. It has some sort of bright debris on it that probably comes from placing it in a transport container that hadn't been cleaned recently enough.
