[1] Unlike other serinethine genera, the distribution of Boisea is very patchy; it is speculated that its highly vicariant range is relictual of what was previously a much vaster, continuous range.

The US species mainly feed on the seeds of maple trees and are occasional nuisance pests around homes.

In North America, Boisea trivittata is native to most of the continental United States, excluding California, and also in center and Eastern regions of Canada, such as Ontario, Quebec,parts of Manitoba and the Atlantic Provinces.

[3] Boisea rubrolineata is native to western continental Canada, found in the distribution area of boxelder maple, such as the Provinces of Saskatchewan, Alberta and British Columbia, and in some places on the United States.
