Phymatodes vulneratus

(LeConte, 1857)

Phymatodes vulneratus is a of longhorn beetle in the Cerambycidae. The species was first described by LeConte in 1857. It is distributed across Canada and the United States. A 1929 study documented larvae infesting dead Vine Maple (Acer circinatum) in British Columbia, representing a new record for the species. The larvae were found in shaded positions, with only 2 of 17 infested maples occurring in sun-exposed locations.

Habitat

Dead wood of Vine Maple (Acer circinatum); larvae collected from trees dead for three years, in wood sections ranging from 0.5 to 6 inches in diameter. Strongly associated with shaded positions—only 2 of 17 infested maples examined occurred in sun-exposed locations.

Distribution

Canada and the United States. Documented from Salmon Arm, British Columbia, Canada.

Host Associations

Acer circinatum - larval Vine Maple; dead wood. New record documented in 1929 from Salmon Arm, B.C.

Life Cycle

Larval stage develops in dead wood of tree. Specific duration of larval development and timing not documented.

Behavior

Larvae exhibit strong preference for shaded conditions.

Ecological Role

Wood-boring ; larvae develop in dead wood, contributing to decomposition of fallen trees.

Taxonomic history

Phymatodes vulneratus was first described by LeConte in 1857. The Phymatodes underwent nomenclatural revisions in 2010 (Swift & Ray), though P. vulneratus was not among the affected by synonymy changes.

Research history

The 1929 note in The Canadian Entomologist represents one of the few detailed biological observations for this , focusing on plant association and microhabitat preference in British Columbia.
