Clytus ruricola
(Olivier, 1795)
Round-necked Longhorn Beetle
Clytus ruricola is a longhorn beetle in the Cerambycidae, first described by Olivier in 1795. It belongs to the tribe Clytini, a group known for -mimicking coloration. The occurs across North America and is one of several Clytus species with distinctive yellow and black patterned . It is a hardwood-associated whose larvae develop in dead or decaying wood.

Identification
Distinguished from other Clytus by the U-shaped middle yellow band on the . reach approximately mid-elytra in length. Similar species such as Clytus arietis and related share yellow and black banding patterns, but specific band shape and antennal length help separate them. The overall -mimicking appearance is characteristic of the but not unique to this species.

Habitat
Associated with hardwood forests. Larvae develop in dead or decaying hardwood. have been observed on flowers, including goldenrod.
Distribution
North America. Documented in Canadian provinces including Alberta, British Columbia, Manitoba, and New Brunswick. GBIF records indicate presence across North America.
Host Associations
- Amorpha fruticosa - food source attracted to flowers
- hardwoods - larval developmentlarvae develop in dead or decaying wood
Life Cycle
Complete with , larva, pupa, and stages. Larvae are wood-borers in dead hardwood. Specific developmental timing not documented in available sources.
Behavior
are flower visitors and have been observed on goldenrod blooms. Exhibits -mimicking coloration as a defensive strategy.
Ecological Role
Larval wood-boring activity contributes to decomposition of dead hardwood. flower visitation suggests potential pollination role, though not quantified.
Human Relevance
Occasional research subject in studies of cerambycid diversity and mimicry. No significant economic impact documented.
