Lulworth skipper caterpillars live in the warmest zone of a grass clump, at a height of . The pupal stage lasts for about two weeks, from the beginning of June onwards, until late July. It is formed inside a loose "nest" of silk and grass that is spun deep inside a tussock of tor grass. Imago begin to emerge in the early middle of July and finish emerging in the middle of September.
