Xylotrechus mormonus
(LeConte, 1861)
Xylotrechus mormonus is a of longhorned beetle in the Cerambycidae, described by John Lawrence LeConte in 1861. It belongs to the tribe Clytini, a group commonly known as the "typical longhorns" or "flower longhorns" for their frequent association with flowering plants. The Xylotrechus contains numerous species across North America, many of which are wood-boring beetles as larvae and flower visitors as . Specific biological details for X. mormonus remain poorly documented in the accessible literature.

Identification
in the Xylotrechus can be challenging to distinguish without close examination. Xylotrechus mormonus would likely share the general of the genus: elongate body, moderately long (typically not exceeding body length in females, slightly longer in males), and often with variable patterns of or coloration. Definitive identification requires comparison with or authoritative keys; no distinguishing features specific to X. mormonus versus are clearly documented in the provided sources. The species name "mormonus" suggests a possible association with the Intermountain West region of North America, an area historically associated with Mormon settlement.

Distribution
North America. Distribution records from GBIF indicate presence in Canada: Alberta, British Columbia, Manitoba, and Ontario. The western Canadian records (Alberta, British Columbia) combined with the specific epithet suggest the may be primarily distributed in western North America, potentially extending into the northwestern United States.

Taxonomic history
The was described by John Lawrence LeConte in 1861, a prolific 19th-century American entomologist who described thousands of North American beetles. The specific epithet "mormonus" likely references the Mormon people or the geographic region associated with them (Utah and surrounding areas), suggesting the may have been collected in that region.
Data limitations
Despite being described over 160 years ago, X. mormonus appears to be poorly represented in modern collections and literature. The 26 iNaturalist observations and limited GBIF records suggest it may be genuinely uncommon, undercollected, or restricted to specific .
