forest, and in decaying sea wrack on the upper margin of a sea beach. Two specimens were collected at M.V. light. Th is species has frequently been collected from caves and was considered a troglophile by Klimaszewski and Peck (1986). However, the presence of this species in other habitat types suggests that A. sulcifrons  is not a true troglophile. This adventive species appears to be associated with decaying organic material. Adults were collected in April, May, August, and September. Collection method: sifting, M.V. light.
