DistributionEurope east to the Russian Far East, Siberia, Tibet and China, south to the Caucasus, Turkey. Also in North America (Alaska to Newfoundland) and south to (North Carolina and California). DescriptionThe name-typical form of ferrugata as figured by Clerck and well described by Linne, has the median band reddish or purplish, the distal area very weakly marked (except the costal patch and two dark spots between the radials) often almost entirely white or whitish. An aberration, ab. unidentaria Haw. is a very common and very interesting aberration which has been proved, by my very extensive breeding experiments and those of Dr. Draudt, to be an almost perfect Mendelian "recessive". It differs in having the median band black, not reddish. — ab. coarctata Prout has the median band greatly narrowed, only 1–2 mm. in width; the rest of the markings often in part obsolete. - bilbainensis Fuchs, from Bilbao, said to be a local race, is described as smaller, narrower-winged, the distal edge of the median band more distinctly biangulate. I doubt its validity. — stupida Alph., from Issyk-kul, Tibet, W. Central China, etc., is rather larger, with whiter hindwing otherwise similar to ab. unidentaria.[1] BiologyThe larvae feed on species of Galium, Stellaria, Campanula and Cirsium.
