On the gray to gray- brown forewings are thin, black, partially serrated transverse lines, which are less pronounced in females and sometimes entirely absent. In the Diskalregion a bright area stands out from the front edge, starting from. The hind wings are pale gray-brown and without markings. The antennae of the males are twice combed, those of the females are very weak kammzähnig. The proboscis is stunted.

Adults caterpillars are marbled brownish in color and show whitish side ridge lines and orange spots. They are hairy striking and wear on the sides of numerous long yellowish hair. On the back are located on segments four to seven dense, upward, usually bluish hair brush as well as on the eleventh segment, a further rear-facing, red-brown hair brush, which has longer hair.

Way of life
Since at the same butterflies, caterpillars and pupae were found by Calliteara fortunata, the succession of generations, further studies are essential in these areas. The males fly during the day and visit at night and artificial light sources. As a food plant of the caterpillars Canary Island pine (Pinus canariensis), Gagel tree ( Myrica faya ) and Adenocarpus foliolosus were detected. On each of the islands different food plants are used.
