Maccaffertium modestum (Cream Cahill) Mayfly Nymph

View 2 PicturesI looked at this nymph closely under my crappy microscope. It has truncate (Truncate: Cut off. This is often used to describe the square appearance of the gills of Maccaffertium mayfly nymphs, for example, as opposed to the pointed gills of the closely related genus Stenacron.) as opposed to rounded gills, postero-lateral (Lateral: To the side.) spines only on abdominal segments 7-9, and oblique crossbars through the center of each sterna, not on the posterior (Posterior: Toward the back of an organism's body. The phrase "posterior to" means "in back of.") edge like on some of the other Maccaffertium species. As best I can tell from the keys this is either modestum or ithaca and from the distribution maps I've seen I'm guessing it's modestum.

Jargon Defined:

Lateral: To the side.

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).

Posterior: Toward the back of an organism's body. The phrase "posterior to" means "in back of."

Truncate: Cut off. This is often used to describe the square appearance of the gills of Maccaffertium mayfly nymphs, for example, as opposed to the pointed gills of the closely related genus Stenacron.
