“Of all the Lepidoptera that have come under our notice, the Caterpillars and Cocoons of the C. Collesi are pre-eminently the most noxious, being armed at all points with stiff bristles and short fine exceedingly sharp hairs, which by careless handling will puncture and adhere firmly to the skin.” Description from AW Scott ‘Australian Lepidoptera and their Transformations’, Volume 1, Plate 7 (1864).
