Baetidae (Blue-Winged Olives) Mayfly Nymph
View 2 PicturesHere's a rather different tiny Baetid nymph. The tails are all unbanded, and the tergites (Tergite: The top (dorsal) part of a single segment on an insect's abdomen.) all have a dark-colored anterior (Anterior: Toward the front of an organism's body. The phrase "anterior to" means "in front of.") 2/3 and light-colored posterior (Posterior: Toward the back of an organism's body. The phrase "posterior to" means "in back of.") 1/3. The gill veinlets (Veinlet: Short insect wing veins connecting the major longitudinal veins to the wing margin.) are indistinct. It's probably a very early instar (Instar: Many invertebrates molt through dozens of progressively larger and better-developed stages as they grow. Each of these stages is known as an instar. Hard-bodied nymphs typically molt through more instars than soft-bodied larvae.) of some Baetis species.
