The Northern Two-lined Salamander lives in and near brooks, streams, and seepages. Like all members of the family Plethodontidae, they lack lungs and absorb the oxygen they need through their skin.
Reproduction starts from September (southern areas) to May (northern areas) depending on the location. Males lay their spermatophores for the females to pick up. The males will nose the female to try to get her to pick them up. Females lay up to 200 eggs on the underside of rocks. Females have been observed guarding their clutches of eggs. Eggs hatch after a month and then the larva take one to three years to complete their metamorphosis.
The International Union for the Conservation of Nature (IUCN) Red List assesses the Northern Two-lined Salamander as Least Concern for Extinction. They have a good size range and are numerous throughout it. However, the salamanders do not like highly urbanized areas which are increasing in their range.
