Extract

The European, or Essex skipper, Thymelicus (= Adopaea) lineola (Ochs.), was accidentally introduced into North America at London, Ontario, sometime before 1910 (Saunders, 1916). The history of its subsequent spread through southern Ontario and adjoining parts of Michigan and Ohio was reviewed by Pengelly (1961), who received the first report of extensive damage to hay and pasture crops by this insect in Ontario from the Markdale area of Grey County in 1956. A survey in 1958 (Pengelly, 1961) showed that the skipper “appeared to be present throughout the southern part of the province except for the Bruce peninsula and possibly the Windsor area. The northeasterly boundary appeared to he along a line from Midland, south around the west side of Lake Simcoe, east to Lindsay and south to Whitby.” The present author collected T. lineola larvae from the Belleville area for the first time in 1959.
