How to identify it
Slender semiaquatic snake, 34-92 cm; brownish or olive above with a yellow stripe along each side extending onto the lip scales. [1][2]
Belly bright yellow with four brownish lengthwise stripes converging toward the tail. [1][2]
Keeled scales (19 rows at midbody), round pupils, divided anal plate; no light stripe down the back, unlike garter snakes. [1][2]
Young show dark horizontal bands on the back. [1][2]
Compared with the garter snakes: Garter snakes have a light dorsal stripe and an undivided anal plate; queen snakes lack a dorsal stripe and have a divided anal plate (Animal Diversity Web). [1][2]
Where it lives
Occurs only where crayfish are abundant, generally in moderate to fast-flowing streams with rocky or sandy bottoms, cover and sun exposure. [1][2]
How it behaves
Eats almost exclusively crayfish, preferring freshly molted ones; occasionally small fish and amphibian larvae. [1][2]
