They can distinguished from the Two-lined Salamander by the presence of a third dark stripe down the middle of the back. Otherwise, the two species share a similar ecology and appearance. Eggs and larvae look very similar, but Three-lined Salamander larvae have much less conspicuous paired light spots running down the back. Three-lined Salamander larvae also have the trace of the middle stripe developing. This becomes much clearer as the larvae develop and approach metamorphosis. Three-lined Salamanders also start breeding earlier in the year in autumn.
