Greenside Darter
Etheostoma blennioides
Greenside Darter is a small North American freshwater perchlet that lives on clean, cool streams with moderate current and rocky bottoms. It forages along the streambed for aquatic insect larvae and other tiny invertebrates.
Identification points
- Olive to green body with distinct blue-green speckling along the sides
- Dark vertical bars on the sides with a more elongated darter shape
- Large pectoral fins and a small mouth, with males often showing blue-green breeding colors
Habitat
Clear, riffle-run sections of small to medium streams and river margins with gravel, cobble, and submerged rocks; usually near algae-coated stones in cool, well-oxygenated water.
Bait notes
Tiny offerings work best: small aquatic insect imitations, micro jigs, 1/32 oz soft plastics, and light live bait such as red worms, small aquatic larvae, or insect nymphs. It is not a common target sport fish.
Behavior
Mostly benthic and diurnal, it sits close to cover and darts short distances to pick small mayflies, caddisflies, chironomids, and other benthic invertebrates from rocks and bottom debris. Males can be territorial during spawning.
Caution
none notable
Fishing notes
Use ultra-light tackle and present baits upstream so they drift naturally along the bottom. Slow dead-drift or short hop presentations through riffles and around rocks are most effective; handle gently and release quickly.
