FAMILY SCRAPTIIDAE (Scraptiid )

L. LeSage

The family Scraptiidae, which comprises about 400 species worldwide and 21 in Canada and Alaska, represents a group of beetles with uncertain affinities. Previously placed either in the , Melandryidae, or Anthicidae, they are now considered a separate family closely related to these (Crowson 1955; Franciscolo 1963; Lawrence 1982a). Adults are often found in numbers on flowers while larvae occur in decaying wood or in leaf litter. There is no recent treatment of the family in North America and the Canadian fauna is poorly known except for the provinces of Quebec and British Columbia. The genus Pectotoma, previously included in the Tetratomidae, was transferred to the Scraptiini by Young (1976).
