Male Siphlonurus Mayfly Spinner
Egg-laying females of this species were the most noticeable insect over the water at dusk on this small trout stream in Wisconsin's Blue Hills. I caught several of them and photographed one, but this was the only male, netted in mid-air mated to one of the females.

Female Siphlonurus Mayfly Spinner
Egg-laying females of this species were the most noticeable insect over the water at dusk on this small trout stream in Wisconsin's Blue Hills. I caught several of them along with one male netted in mid-air mated to one of the females.

Female Heptageniidae Mayfly Spinner
I only caught a couple of these, and they were both females, so I'm not sure I'll be able to identify it any further.

Dibusa angata Caddisfly Adult
I'm tentatively classifying this one as Dibusa angata because I cannot see any ocelli in my dorsal view of the head (and because it has a single spur on each front tibia). However, sometimes they can be difficult to spot when obscured behind setae in general, so I'm not 100 % sure on this one. If there are ocelli I missed, then based on ranges and colors the genus ought to be Stactobiella.
