The long-wing forms fly and have been collected in rotary traps. WLM collected one specimen "on mullen" (sic), They were observed running in the sunshine and mating on cloudy and rainy days (Larochelle, 1975a). Several examples were collected on the Island and adjacent shores between 1902 and 1963 (HSB, WLM, EAS, OLC, PJS & TPC). There are no recent records. No teneral specimens seen. Adults were collected in January, February, March, April, May, August, October and November. Hibernation takes place as an adult.
