Drake spinners? Penns

[sipe]

How long will spinners hang on in an area? I was hoping to fish Poe paddy Saturday evening. The swarm was hatching Sunday there....any thoughts?

as long as there are some duns there will be spinners. drakes hatch during the day and early evenings then rest and molt to next night when they take flight and mate as spinners. once mated the female will lay her eggs and die that night while the male may live for another day maybe.
