FAUNAL ASSEMBLAGES AND DISTRIBUTIONAL SHIFTS OF COLEOPTERA DURING THE LATE PLEISTOCENE IN CANADA AND THE NORTHERN UNITED STATES

Abstract A faunal list of 362 sub-fossil Coleoptera obtained from 33 published and 24 unpublished sites of Pleistocene age in Canada and the neighbouring United States is given. A table indicates the

Early Weichselian Insect Faunas from Northern Sweden: Climatic and Environmental Implications

Insect remains from Early Weichselian interstadial deposits in northernmost Sweden were studied. A total of 93 taxa were identified in samples from 17 sites. Beetle remains dominate the assemblages

Paleontology of leaf beetles

The fossil record of the Chrysomelidae can be tentatively traced back to the late Paleozoic to early Mesozoic (Triassic) and can be frequently identified to genus, especially if preserved in amber.

Weevils (Coleoptera: Curculionoidea, Excluding Scolytinae and Platypodinae) of the Yukon

Four distinct assemblages are distinguished in the curculionoid fauna: widespread: an assemblage consisting of 47 widespread species found in boreal and/or boreomontane forest, wetlands, or a variety of habitats and generally characteristic of northern transcontinental North America (and for some species also Eurasia).

Coleoptera (beetle) fossils play an important role in paleoecological research, but as yet have contributed little information bearing on dating and correlation. The reason for this is that most

Insect remains, chiefly of beetles, have been obtained from a Late Pleistocene organic mud which was interbedded within the Middle Sands at Chelford, Cheshire, and it has been possible to deduce much of the ecology of the district at the time of the deposition of the organic mud.

The fossil occurrence of Helophorus arcticus Brown (Coleoptera: Hydrophilidae) in Pleistocene deposits of the Scarborough Bluffs, Ontario

It is suggested that such conditions probably prevailed in the Toronto region during the deposition of the Scarborough Formation 70 000 years ago, and points out the vast changes in insect distribution which have taken place during and since the last glaciation.

The economic importance of the genus is not great; the hahit of breeding in the unthrifty lower branches of coniferous trees contributes slightly toward accelerating the natural pruning of the trees and consequently aids in the production of a higher quality of timber.
