Strophiona nitens
(Forster, 1771)
chestnut bark borer
Strophiona nitens, commonly known as the chestnut bark borer, is a of flower longhorn beetle in the Cerambycidae. It is native to North America and has been documented across multiple Canadian provinces and U.S. states. The species belongs to the Lepturinae, a group characterized by their flower-visiting . Despite its referencing chestnut, specific ecological relationships with this plant require further verification.

Identification
As a member of the Lepturinae , Strophiona nitens can be distinguished from other cerambycid subfamilies by its flower-visiting and associated morphological adaptations. Within the Strophiona, identification to level requires examination of specific morphological characters including antennal structure, pronotal shape, and elytral . The species may be confused with other Lepturini tribe members, but definitive identification typically requires reference to specialized taxonomic keys for North American flower longhorns.

Distribution
North America. Documented occurrences include the Canadian provinces of Manitoba, New Brunswick, Nova Scotia, and Ontario. The has also been recorded in the United States, though specific state records require further verification from primary sources.
Behavior
Members of the Lepturinae , to which this belongs, are known as 'flower longhorns' due to their habit of visiting flowers for nectar and pollen. This distinguishes them from many other cerambycid beetles whose larvae are strictly wood-borers.
Human Relevance
The 'chestnut bark borer' suggests potential historical or ongoing association with chestnut trees (Castanea spp.), though the precise nature of this relationship—whether as a pest, casual inhabitant, or simply collected from such —requires verification. The species has been documented through citizen science platforms with 388 observations recorded on iNaturalist as of the knowledge cutoff.

More Details
Taxonomic history
Originally described as Leptura nitens by Forster in 1771, the was later transferred to the Strophiona. The basionym Leptura nitens reflects the historical classification of many flower longhorns within the broadly defined genus Leptura before modern generic revisions.
Data availability
The has accumulated 388 observations on iNaturalist, indicating moderate documentation through citizen science, though detailed biological studies appear limited in the accessible literature.
