Female Dicosmoecus gilvipes (October Caddis) Caddisfly AdultFemale Dicosmoecus gilvipes (October Caddis) Caddisfly Adult View 16 PicturesI've been hoping to add a really good October Caddis to the photo collection here for years, but so far I had struck out on finding them on the river. Tonight, this one flew into the kitchen during a pizza party at a house along the river, and was quickly pointed out -- one of the perks of hanging out with other aquatic biologists! Maybe next year I can finally get a salmonfly on taco night or something.

Male Heptagenia culacantha Mayfly SpinnerMale Heptagenia culacantha Mayfly Spinner View 1 PicturesThis photo was provided by guide Eric Naguski along with the following comments, "I took this photo just upstream of Three Mile Island on the east shore of the Susquehanna River just below where the Swatara Creek enters. The Susquehanna is not an easy river to sample for bugs in my opinion. It is very large and pushes a lot of water. Especially in the spring when you would collect mature culacantha nymphs. And I don't believe that there are a ton of these Heptageniids around. Also the people who are doing most of the sampling like myself are doing so for water quality monitoring work so they only take the specimens down to genus-level taxonomy".

Polydrusus (Green Weevils) Beetle AdultPolydrusus (Green Weevils) Beetle Adult View 3 PicturesThis is an iridescent green terrestrial (Terrestrial: Insects which live on land and are fed on by trout only when they incidentally fall into the water are known as "terrestrials" to fly anglers, and they're very important in late summer.) beetle. They're common in northern Wisconsin's forests during the middle of summer, and I found them on the water's surface more than any other terrestrial (Terrestrial: Insects which live on land and are fed on by trout only when they incidentally fall into the water are known as "terrestrials" to fly anglers, and they're very important in late summer.) insect. I saw the trout take a few and caught some trout on an imitation.
