The blenny darter (''Etheostoma blennius'') is a poorly known species of fish in the family Percidae, from Alabama and Tennessee that inhabits swift riffles. ==Biology== The blenny darter lives a maximum of two to three years, grows to a maximum of 69 mm standard length, and is sexually mature at one year.〔(Burr, Brooks M (1979). Systematics and Life History Aspects of the Percid Fish ''Etheostoma blennius'' with Description of a New Subspecies from Sequatchie River, Tennessee. ''Copeia.'' 1979 (2): pp. 191-203. )〕 It is reproductively active throughout March and April. Spawning occurs over gravel riffles with swift currents. Mature eggs are orange and translucent. The fish are insectivorous, with analyzed gut contents containing Nematocera larvae, more specifically black fly (Simuliidae) and midge (Chironomidae) larvae. Significant numbers of mayfly (Ephemeroptera) and caddisfly (Trichoptera) nymphs were also found.
