Det. John H. Acorn, 2013
s CAN and n US, south in the east to at least North Carolina, south in the west to Oregon
native to the Old World, occurs in Europe, western Asia, and the Middle East; introduced to North America (no info available on date or location)
weedy fields and meadows; adults often found on flowers of herbaceous plants
adults present mostly May-June (BG data)
adults may feed on flower-visiting insects and/or pollen
larvae are presumably predeacous on immature invertebrates
In 2005, Buglife, a UK charitable organization devoted to the conservation of invertebrates, lauched the Scarlet Malachite Beetle Project, requesting members of the general public to report sightings of Malachius aeneus, whose numbers have declined in England in recent years.
The Checklist of Beetles of Canada and Alaska (referenced below) states that M. aeneus "...causes considerable damage to developing wheat in the Prairie Provinces." and yet the same document does not list the species as occurring in Manitoba or Saskatchewan.
