greenside darter
The greenside darter (''Etheostoma blennioides'') is a species of fish in the family Percidae. It is a large percid inhabiting swift riffles in the eastern United States and southern Ontario.
== Biology ==
Greenside darters typically live for three to five years, grow to a maximum of 132 mm standard length and sexually mature at one to two years of age. Greenside darters are reproductively active from February to April in the Midwest and Southeastern United States. Spawning occurs over algae- or moss-covered rocks in deep, swift riffles that are guarded by males that vigorously defended against intruders. Females linger in pools below the riffle and move into a male's territory when ready to spawn. Eggs are viscous and stick together in small clumps on green algae (''Cladophora''), moss (''Fontinalis''), and riverweed (Podostemaceae). ''E. blennioides'' is insectivorous, with analyzed gut contents containing Nematocera larvae, more specifically black fly and midge (Chironomidae) larvae. Significant numbers of mayfly (Ephemeroptera) and caddisfly (Trichoptera) nymphs were also found.
