Male Ephemerella aurivillii Mayfly DunMale Ephemerella aurivillii  Mayfly Dun View 14 PicturesThis is the most widespread species of Ephemerella, and also the most abundant in some places, but nobody I've talked to seemed to know what its duns looked like, and there were no pictures of its duns online or in any angling books. That mystery is solved with this male dun, which hatched from a definitively identified nymph.

Isogenoides hansoni (Appalachian Springfly) Stonefly NymphIsogenoides hansoni (Appalachian Springfly) Stonefly Nymph View 11 PicturesThis large Perlodidae stonefly was a strikingly bright yellow color, more so than any other insect I've seen. I didn't enhance it much. See the discussion threads to follow how we identified this specimen, which was listed incorrectly for several years.

Formicidae (Ants) Ant AdultFormicidae (Ants) Insect Adult View 7 PicturesI 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.

Belostoma flumineum (Electric Light Bug) Giant Water Bug AdultBelostoma flumineum (Electric Light Bug) Giant Water Bug Adult View 13 PicturesI'm glad I finally got one of these Belostoma water bugs under my good camera. I had been hoping to get one in my kick-net samples for a while with no luck, but I ended up finding this one drifting midstream just below the surface while I fished. I have frequently seen water scorpions do that, too, and I'm beginning to suspect that is a common situation travel for these large Hemiptera bugs, and perhaps the way trout are used to seeing them.
Collected April 24, 2007 from the West Branch of Owego Creek in New York

Male Ephemerella subvaria (Hendrickson) Mayfly DunMale Ephemerella subvaria (Hendrickson) Mayfly Dun View 9 PicturesI collected this male Hendrickson dun and a female in the pool on the Beaverkill where the popular Hendrickson pattern was first created. He is descended from mayfly royalty.

Male Stictochironomus Midge AdultMale Stictochironomus  Midge Adult View 11 PicturesThis midge and several like it, including a female I also photographed, hatched from larvae which were living in some fine mud I'm using as substrate in my bug-rearing aquarium.
