Martania taeniata, the barred carpet, is a moth of the family Geometridae.

[1] It is found in large parts of the Palearctic realm.

The large white or whitish spot in the middle of the distal margin distinguishes M. taeniata from its nearest allies.

[2] [3] There is one generation per year with adults on wing in July and August.

The larvae probably feed on various moss species in the wild, but have been reared on various plants, such as Taraxacum officinale, Stellaria media and Polygonum aviculare.
