Cordulegaster Dragonfly Nymph

View 4 PicturesThis is a realy big, dark dragonfly nymph. Notice how "fuzzy" it is--it's covered with small hairs that collect sediment and debris and camouflage the nymph to match its natural surroundings. The greenish cast in some of the photos of this specimen is due to strange lighting during my first night photographing things for this site.

Apatania (Early Smoky Wing Sedges) Caddisfly Adult

View 7 PicturesThis one actually had a medium tan body when it emerged. By the time I took the picture it was dark as night. I was actually looking through my box of specimens trying to figure out where that tan one I caught disappeared to. Then I realized this is it.

Jargon Defined:

Natural: A natural is a real insect (or similar creature) a trout might eat. The term is used to specify the real thing as opposed to its artificial imitation.

Nymph: The juvenile, underwater stages of mayflies, stoneflies, dragonflies, and damselflies and other aquatic insects whose juvenile stages are covered by hard exoskeletons. The word can also refer to the fishing flies which imitate these creatures, in which case it is used as a blanket term for flies imitating any underwater stage of an invertebrate (except for crayfish and leeches).

Terga: the dorsal part of an abdominal segment or segments (terga). Also used to describe the entire abdominal dorsum or the thoracic dorsal segments of Odonata.
