Scientific name: Zygaena trifolii
May to August. Southern England, Wales, Isle of Man. Medium-sized with black forewing with five red spots. Lives on damp grassland, chalk downland, and heaths. Can be confused with the Narrow-bordered Five-spot Burnet.
Very similar to and sometimes difficult to distinguish from the Narrow-bordered Five-spot Burnet. Consequently, the distribution of the Five-spot Burnet is imperfectly known. In general, the forewing of the Narrow-bordered Five-spot Burnet is longer and more pointed, the upper angle of the hindwing being more pointed and the black border of the hindwing being narrower than those of the Five-spot Burnet. Rarely the red colour is replaced by yellow.
Sometimes found commonly, the moth flies with a slow buzzing flight during sunshine and visits a range of flowers.
