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.

We were lucky to be able to fish through this storm as it skirted around us to the north, giving us just enough clouds to prompt a BWO hatch but keeping the lighting at a safe distance. From Slough Creek in Wyoming

Case view of a Limnephilus (Limnephilidae) (Summer Flier Sedge) Caddisfly Larva from the Yakima River in Washington
This seems to be a young larva of Limnephilus. Although not clear in the picture, several ventral abdominal segments have chloride epithelia.

27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Landscape & scenery photos from the Neversink River

Neversink Gorge (Wolf Brook) in New York
This beautiful, remote stretch of one of the lesser-known large Catskill trout streams produced my only trout in two days of slow fishing, a 9 inch brown. Better than nothing! In fact, even "nothing" in this setting is really something! From the Neversink River Gorge in New York
You've really got to see this one full-size to enjoy it. It's my first attempt at a 360 degree panorama stitched together with the latest and greatest version of Adobe Photoshop. From the Neversink River in New York
Do you ever have so much fun trying to fool a fish that you're almost disappointed when you actually do? I got that feeling after who knows how many casts over this hungry little brown with a Trico imitation.

This Ephemerella invaria sulphur dun got stuck in its shuck trying to emerge. This isn't exactly a "natural" pose for a photograph, but it kind of shows what an emerger pattern could look like. From the Neversink River in New York
I saw something strange flying around near the streambank, fluttering on and off the water's surface, so I went to check it out. I didn't recognize the wing profile in flight, and it's no surprise! These two caddisflies were joined mating, and they were very reluctant to let go. From the Neversink River in New York

I'm not sure what these clusters of grannoms are doing lying dead and mostly upside down in clusters on the rocks. Anyone have an explanation? From the Neversink River in New York

This Baetisca obesa dun hatched out in my aquarium from nymphs collected a couple weeks earlier.

Lateral view of a Neophylax (Thremmatidae) (Autumn Mottled Sedge) Caddisfly Larva from the Neversink River (above reservoir) in New York
The size of the head compared to the body in this larva is surprising, and I think this means it's a fairly early instar of something which is going to get a lot bigger, but I'm not sure.

Female Neoleptophlebia Mayfly Dun

I'm just guessing Neoleptophlebia on this one. It could easily be Paraleptophlebia.

Formicidae (Ant) Insect Adult
Lateral view of a Formicidae (Ant) Insect Adult from the Neversink River in New York
I collected this flying ant from the surface of a popular Catskill trout stream, where its species prompted steady rising from selective trout for several late-morning hours. It was mixed with smaller ants of a different color, and I photographed one of them too.

Female Tricorythodes (Trico) Mayfly Spinner
Lateral view of a Female Tricorythodes (Leptohyphidae) (Trico) Mayfly Spinner from the Neversink River in New York
I photographed this Trico alive, although it didn't have much time left. These things die very quickly after they mate and it's hard to rush them back to the studio.
