Status insufficiently known, because most of the species of this genus should be checked for genitalia. Often confused with Dichrorampha flavidorsana. Assumed to be a very rare species in Belgium.
Native
Wingspan 13–15 mm. Very similar to Dichrorampha flavidorsana, but distinguished by a comparatively broad medio-dorsal blotch on the forewing, a fuscous hindwing that gets slightly paler towards the base and the costal fold of the male reaches to just over one third.
Genital dissection is needed for confident separation of these species.
A brightly coloured moth with a large yellow/orange dorsal patch, plumbeous striae from pale costal strigulae on the terminal half of the costa and with prominent black spots on the termen. There is prominent orange shading around the terminal spots, plumbeous striae and apex. There are black dashes associated with the plumbeous striae.
Whitish body with head and prothoracic plate light brown.
The larva bores in the roots on the host plant.
The moths fly often during the daytime when they can be found resting on flowers of the foodplant. Later they come to light.
The adults have been observed from mid-May towards late August.
The larva lives on Leucanthemum vulgare.
It inhabits flowery grasslands, ditches, wasteland and roadsides.
