Rolled-winged Stonefly - Leuctra duplicata - female

Rolled-winged Stonefly - Leuctra duplicata - Female
Fitchburg, Worcester County, Massachusetts, USA
May 18, 2009
Size: 6mm body
I didn't realize stoneflies had a molt after emerging, just like a mayfly subimagio. When I got this one out of the vial to photograph it a few hours after catching it, I noticed a shed skin in with the adult.

Leuctra duplicata
female

Exuvia...
was probably nymphal. Stonefly nymphs crawl out of the water to emerge, and perhaps the nymphal exuvia was still attached when you collected the adult.

 
Strange
I collected this as an adult by sweep netting vegetation at the edges of a sand pit. I'm not even sure where the water is that it came from.
