Comparison with Related Species

Compare with:

The size and shape of the shiny adults make it distinctive enough so that it is unlikely to be confused with other species. From the somewhat similar B. lorquinii distinguished externally by the wider body and presence of midlateral pronotal seta.

Geographic Distribution

The range of this species is disjunct, as it is apparently absent from the center of North America. From New Brunswick and Maine south to Kentucky and Arkansas; in the west from Saskatchewan and Montana, to the Yukon.

Habitat

On barren sand banks of rivers and lakes. Adults are found on the drier areas of the sand banks, occasionally at a considerable distance from water.

This page is a Tree of Life Leaf Page.

Each ToL leaf page provides a synopsis of the characteristics of a group of organisms representing a leaf at the tip of the Tree of Life. The major distinction between a leaf and a branch of the Tree of Life is that a leaf cannot generally be further subdivided into subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
