Brachysomida bivittata

The combination of small size (7–11 mm), Lepturinae subfamily characteristics, and geographic occurrence in the northern Great Plains and eastern Canada distinguishes this species from larger or differently distributed cerambycids. The three described varieties (fusciceps, nigripennis, varians) suggest color pattern variation that may complicate field identification. Specimens from Nebraska and the Prairie Provinces should be compared against other Brachysomida species, particularly B. californica and B. hirsutula, which have different western distributions.

A small longhorn beetle measuring 7–11 mm in length. As a member of Lepturinae, it possesses the characteristic elongate body form and moderately long antennae typical of flower longhorn beetles. The specific epithet 'bivittata' (two-banded) suggests two longitudinal stripes or bands on the elytra, though detailed coloration patterns require direct specimen examination.

Canada (Alberta, Manitoba, New Brunswick, Nova Scotia) and north-central United States (Nebraska documented; North American range generally).

• Brachysomida californicaOverlaps in some western areas; differs in distribution and likely elytral pattern
• Brachysomida hirsutulaSimilar size and form; western distribution distinguishes it from B. bivittata
• Other LepturinaeMany flower longhorn beetles share general appearance; accurate identification requires examination of specific elytral patterns and geographic provenance
