Two-lined salamander
(Eurycea bislineata)

IDENTIFICATION: Range in size between 6.4-9.5cm. Record longest 12.1 cm. A yellow belly, smaller and more slender body, and two dark lateral lines from eye to tail distinguish this salamander from the Northern dusky. Two-lined also lacks the two pale stripes from eye to jaw. Coastal grooves 15-16.
CONSERVATION BIOLOGY: The two-lined salamander is sensitive to intensive timbering, land clearing, stream pollution and siltation, and it is not found in urban areas and highly disturbed landscapes. They are not found in New York where low pH in soils results in disruption of the sodium balance, and acid rain can cause serious issues.
HABITAT: Found beneath logs and rocks along the margins of rocky streams or seeps, but also occur in forested areas away from water.
BREEDING/LARVAE: Adults breed from September to May. There is a limited amount of observations on the courtship of the two-lined salamander in nature. The ratio between the salamander's courtship on land versus water is unknown. Mostly females deposit their eggs on the undersides of rocks in streams. Females stay close to their eggs before and shortly after they are hatched to protect them from predators.
PREDATORS: They are eaten by a variety of predators including Eastern screech owls (Otus asia), common garter snakes (Thamnophis sirtalis), and ringneck snakes (Diadophis punctatus). Spring and black-bellied salamanders are major predators on larvae and adults in some portions of the range. Rainbow trout and two-lined salamanders are mutual predators.
FOOD: In addition to the rainbow trout, the two-lined salamander feeds on a variety of items. These include: beetles, spiders, sowbugs, mayflies, dipterans, annelids, stonefly nymphs, and thrips.
RANGE: Occur from southeastern Canada to the Gulf Coast with the western boarder being Louisiana, Arkansas, ad Illinois.
