SUMMARY
Commonly found along both sides of the Channel on the primary and secondary floodplain which consists of sand and silt; often found in great numbers. In our area, these beetles are not restricted to bare sites, but may be found up in the floodplain forest where the adults hibernate under leaves, logs, and even under bark. During the day, both the larvae and adults hide in burrows in the sand; they come out to forage at night. These beetles are fully winged and according to Larochelle (1972, 1975) they fly on humid and sunny days. Many examples were collected on the Island and adjacent shores between 1905 and the present (HSB & EAS, WLM, RCS, JLW, PJS, GGP, TLE & DRW). No teneral specimens seen. Adults were collected in March, April, May, July, August, September and October. According to Lindroth (1961) adults hibernate. Larochelle (1974) found these beetles hibernating on "mounds" in November, in Quebec. Total length, 5.1 to 7.0 mm (6.0).
