Callisthenes (Chrysostigma) calidus (Fabricius) 1775
According to Lindroth (1961b) "terricolous and inhabits open rather dry fields with low vegetation." These are poor climbers, but will go up the trunk of trees for caterpillars occasionally. Both adults and larvae are predaceous on cutworms, and they will also eat tent caterpillars and army worms (Burgess and Collins, 1917). They can be collected by tying burlap sacks around the lower trunks of trees, a device which congregates their prey; they will also come to sugar used for "sugaring" for moths. They are fully winged and probably fly quite well; they are attracted to lights. They are both nocturnal and diurnal according to Larochelle (1975a). Only one specimen was collected on the Island, in 1913 "at light". There are no recent records. No teneral specimens seen. Adults overwinter and are found in the late spring and throughout the summer (seen from May). Larvae are present in the fauna in summer. A long and detailed report on their bionomics is given by Burgess and Collins (1917). Total length, 19.0 to 25.0 mm (22.0).
