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.
