is 34–48 mm. Wing pattern is very variable, from entirely white wings to strongly covered with black dots. Hindwings often with one or several black dots (rarely without any black dot). Antennae branches long (much longer than in similar '' Spilosoma urticae''), 3–5 times longer than the antenna stem diameter.


Technical description and variation

Milky white, abdomen orange with black dorsal dots. Forewing more or less sprinkled with sharply defined black dots, of which there are always some at the costa and others arranged in rows in the disc. Hindwing with discal dots and often with anal ones and others. Antennae black. In specimens from northern Scotland the forewing is sandy yellow, ab. ''ochrea'', also found elsewhere as an exception among. The forewing may be darkened to brown; this is the case in ab. ''brunnea'' Ober. In ab. ''luxerii'' Godt. the forewing is suffused with rose-red distally and brownish proximally. In ab. ''walkeri'' Curt, the dots merge to form radial streaks. In Japan it usually occurs in the form ''sangaica'' Walk. which is only distinguished from ''lubricipeda'' by the sparse dots, especially in the outer area of the forewing. Specimens similar to ''sangaica'' occur aberratively also in Europe, bearing the name ''paucipuncta'' Fuchs and in contradistinction to it there is the very strongly dotted ''krieghoffi'' Pabst. A still further reduction of the dots leads to ab. ''unipuncta'' Strand, in which there is only one dot on the hindwing. -''punctarium'' Cr. ow_full_species_''Spilosoma_punctarium''_(Stoll,_[1782.html" ;"title="Spilosoma_punctarium.html" ;"title="ow full species ''Spilosoma punctarium">ow full species ''Spilosoma punctarium'' (Stoll, [1782">Spilosoma_punctarium.html" ;"title="ow full species ''Spilosoma punctarium">ow full species ''Spilosoma punctarium'' (Stoll, [1782] is distinguished from ''lubricipeda'' by the carmine abdomen with sharp transverse spots, and by the wings being rather more spotted.
