Superficially similar to several of the other burnet moths, but readily distinguished by the thinly-scaled forewing with three blunt red streaks. Rarely this red colour is replaced by black, orange or yellow. The Slender Scotch Burnet and Scotch Burnet are also thinly-scaled, but are usually smaller and have distinct spots rather than streaks.

Flies in warm weather, preferring sunshine. During dull weather it can be found sitting exposed on flowerheads or grass stems. Visits nectar sources, such as Wild Thyme.
