Blue-winged Olives
Baetis

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.

Mayfly Species Leucrocuta hebe (Little Yellow Quill)

This widespread species produces more fishable hatches in the East and Midwest than any other species in the Heptagenia genus complex.

Where & when

Time of year : Late May through October; best in early June

The best hatches are reported from the Upper Midwest.

Hatching behavior

The duns emerge and fly away very quickly, making them usually pointless to imitate. Spinners are more likely to be relevant.
