Breeding Usually, Northern Long Toed Salamanders breed between January and June. Generally, breeding season is determined more by latitude than by temperature. Northern Long Toed Salamanders undergo amplexus, and then they lay their eggs on submerged vegetation. They may lay the eggs in clusters or singles. The single eggs are generally found closer to the surface, while clusters may be in the deepest area of the water in a protected area such as the underside of a log. Usually, the eggs hatch in about three weeks, and the Northern Long Toed Salamanders will generally remain in the larval state until the summer after they were hatched.
