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.

It's amazing how much abdominal length is given up in this process. The egg packet looked black in the hand.
