FAMILY MELYRIDAE (Soft-winged flower beetles)
D.E. Bright
This family includes 50 species from Canada. The adults occur commonly on flowers and evidently feed on other insects as well as on pollen. Larvae are primarily predators, occurring in various habitats but most commonly in soil, leaf litter or under bark. One species, Malachius aeneus, has been introduced into North America and causes considerable damage to developing wheat in the Prairie Provinces. The taxonomy of the North American melyrids is in poor condition and the family is in need of careful study. There are no recent revisions or taxonomic treatments of the Nearctic species; therefore the list below reflects our best effort at achieving a list based on available literature. A key to the genera will be found in Arnett (1968); Hatch (1962) gives a key to the species from the Pacific Northwest.
