Richard South, The Moths of the British Isles… (1920)
“ The caterpillar, which feeds in July and August on the leaves of oak, beech, sloe, and apple, etc., is reddish, inclining to yellow on the back, which is traversed by black lines, the central double and interrupted on rings seven to nine by rusty V-shaped marks.The moth flies in May and June.This species appears to have a wider distribution than either of the others. It is the only one known with certainty to occur in Ireland, and it is widely spread in that country. In Scotland it is found in Perthshire and Ayrshire, and probably is present in other parts. ”
