The lined firetail skink breeds in the dry season and lays only a handful of eggs (one to three eggs) in each clutch.

It is active during the day, a swift moving and alert species that lives on the ground. As with most small skinks it feeds on insects and other small arthropods. The Lined Firetail Skink is also known to eat ants.

There are two subspecies of lined firetail skink. Morethia ruficauda exquisita (is known as the exquisite fire-tail skink) and is distinguished from Morethia ruficauda ruficauda by the light stripe running along the top of its back1.
