Mating season for eastern red-backs begins in sometime between October through December. Males will follow the pheromone trails left by the females. The courtship initiates with the male rubbing his head on the female's snout. After the rubbing has ceased the male then deposits the spermatophore and the female retrieves it. A very large amount of energy is required for the females to produce their eggs, so it is thought that they only breed once every other year. She lays her eggs sometime in the summer.

Physical Description
Geographic Distribution & Habitat
Eastern red-backed salamanders can be found as far south as North Carolina, west over to Ohio, and north into New England through Nova Scotia. They can be found in varying types of forests, from deciduous or coniferous. Dry or sandy soils will usually be avoided by this species. Like most salamanders one can find them hidden under logs, leaf litter, and rocks as they are most active during the night.
Ecology
Their role in the ecosystem of soil is vitally important, especially in regards to the fungal community. Many invertebrates feed upon fungus as a source of nutrition. The salamanders ensure a balance is kept by controlling the populations of these insects [2].
Reproduction
Mating season for eastern red-backs begins in sometime between October through December. Males will follow the pheromone trails left by the females. The courtship initiates with the male rubbing his head on the female's snout. After the rubbing has ceased the male then deposits the spermatophore and the female retrieves it. A very large amount of energy is required for the females to produce their eggs, so it is thought that they only breed once every other year. She lays her eggs sometime in the summer. Eggs then hatch two months later in August or September.
