With a bit of help from the microscope, this specimen keys clearly and unsurprisingly to Hydropsyche.

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.

Formicidae (Ant) Insect Adult Pictures

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.

I had a great morning fishing to flying ants in the Catskills on September 5th. At least a few fish were rising steadily in every pool on my selected stretch of the Neversink, and flying ants were abundant in the air and on the water for hours.

There were two types of ants which I collected and photographed this large, rusty-tinted variety and a smaller type. I'm curious: were they two different species, or different-looking males and females of the same species?

Many ants were descending to the water in pairs, presumably mating. I hadn't yet noticed the difference in sizes, so I didn't check to see if each pair had one large and one small ant.
