Blue-winged Olives

Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

Troutnut is a project started in 2003 by salmonid ecologist Jason "Troutnut" Neuswanger to help anglers and fly tyers unabashedly embrace the entomological side of the sport. Learn more about Troutnut or support the project for an enhanced experience here.

I know in North Alabama these flies usually hatch in Jun. What climate/water temperatures are required for hatching? Does it normally have to be dry/no rain for a week?

Thanks to anyone who can answer these questions. I promised my 12 year old, I was going to take him this year and I'm trying to plan my leave at the closest possible time.
