Map Į3. Collection localities in New Brunswick, Canada of Gennadota canadensis .

Bionomic Notes. Most individuals of G. canadensis were collected from among decaying vegetables (compost) either within or adjacent to a commercially available plastic compost bin near a mixed forest in a small residential area. Others were collected from moist leaves under sap flows from recently cut or wounded trees, decaying mushrooms and moose dung in mixed forests. In Nova Scotia, G. canadensis was collected on dead pigs, a decaying gilled fungus, on decaying Ganoderma shelf-fungus, and in a pitfall trap among broken rocks and leaf litter at the entrance of a cave ( Majka et al. 2006b). Prior to Majka et al. (2006b) records, only three specimens of this species were known, two from caves ( Klimaszewski and Peck 1986; Klimaszewski and Pelletier 2004). Our data suggest that G. canadensis is a forest species associated with decaying organic matter and may only occur in caves incidentally. Collection method: sifting.

Adults were collected in late March, April, May, September and October. One adult collected in October was teneral. Four adults were captured in a flight intercept trap adjacent to a plastic composting bin on a warm day (12°C) in late March when a partial snow cover was still present. Gennadota canadensis probably overwinters in the adult stage and appears to become active very early in the spring.
