Features
Butterfly
The color of the forewings varies greatly. So there are ocher-colored copies and those with gray-brown tint. The midfield usually occurs out slightly darkened. Blemish stand out dimly from or missing. Outer and inner transverse line are dark brown to black and run in large sheets or waves. With a wingspan 18-25 mm include the imagos of the smaller cutworm species. The hind wings are colored almost without markings gray brown. The antennae of the males are saw-toothed. The females have a slightly longer abdomen, usually with prominent ovipositor.
Caterpillar
Adults caterpillars are reddish in color and show broad whitish side ridge lines and side stripes and black spiracles.
Similar Species
The color of occurring in southern Spain and North-West Africa on average slightly larger type Cleonymia diffluens tends more to black-brown tints and fainter drawing elements.
Geographical distribution and habitat
The distribution area of Cleonymia yvanii includes parts of Portugal, the north-eastern Spain, southern France and a part of North Italy. The species occurs mainly on rocky southern slopes and dry lawns.
Way of life
The moths fly in one generation from late April to mid-July. At night they visit very much artificial light sources. The caterpillars live in late summer and feed on sun Rösch species ( Helianthemum ). The species overwinters as a pupa.
Taxonomy
Since Cleonymia yvanii varies greatly in size and color, it was in the past, some confusion in determining the type, as different and false geographical assignments were not true subspecies and form names used by some authors. So C. diffluens was temporarily considered as a color or as southwestern subspecies of C. yvanii, now however, as two distinct species, they are out.
