During the summer of 1957, collections of insects from burrows of the woodchuck, Marmota monax, were made hv the senior author in the vicinity of London, Ontario. The collector obtained the insects by reaching into a burrow for a distance of about one yard and scraping out by hand the loose soil at the bottom of the burrow from the outer one yard of the length of the burrow. The accumulation of soil and debris thus obtained was combed over and insects were removed from it. By this method insects were collected from thirty burrows, and these were sorted according to order and family and sent to taxonomic specialists for identification.
