Temnoscheila virescens

Fabricius, 1801

Temnoscheila virescens is a predatory in the Trogossitidae, commonly known as bark-gnawing beetles. Research demonstrates that this is attracted to cerambycid beetle , specifically 3-hydroxyhexan-2-one, with ethanol enhancing this attraction. This chemical eavesdropping indicates a -prey relationship with longhorn beetles (Cerambycidae). The species belongs to a family whose members are typically associated with dead or dying wood .

Identification

Members of Trogossitidae can be recognized by their convex, often bullet-like body shape and bead-like . T. virescens specifically would require examination of morphological features for definitive identification from . The is distinguished from similar-appearing groups such as Tenebrionidae (darkling beetles) by behavioral and structural traits including exposed jaws and relatively slow movement compared to the agile, often iridescent Trogossitidae.

Habitat

Associated with bark and wood-boring ; likely occupies dead or dying wood environments given -level and prey associations.

Distribution

Documented from north Georgia and South Carolina in trapping studies; broader North American distribution requires additional confirmation.

Diet

, with demonstrated attraction to cerambycid beetles (Cerambycidae) via exploitation of their .

Host Associations

Cerambycidae - -preyAttraction to 3-hydroxyhexan-2-one indicates predatory relationship with longhorn beetles

Behavior

Exhibits -mediated foraging , using cerambycid beetle (3-hydroxyhexan-2-one) as chemical cues to locate prey. Ethanol enhances pheromone attraction, suggesting synergistic response to tree volatiles combined with prey signals.

Ecological Role

of wood-boring beetles, potentially contributing to of cerambycid . The use of prey for foraging represents a form of intraguild or direct within dead wood .

Similar Taxa

Chariessa pilosaBoth attracted to cerambycid and function as of bark and wood-boring beetles, but C. pilosa responds to syn-2,3-hexanediol rather than 3-hydroxyhexan-2-one and belongs to Cleridae (checkered beetles)
Lecontia discicollisSimilar convex, bullet-like body form and slow movement, but belongs to Boridae (conifer bark beetles) with different structure and association with fire-killed conifers rather than cerambycid prey

More Details

Chemical Ecology

Research in 2011–2013 demonstrated that T. virescens attraction to 3-hydroxyhexan-2-one was enhanced by ethanol, a common tree volatile. This suggests the uses a combination of prey and host plant cues for foraging.

Taxonomic Note

GBIF lists this as a synonym under Temnochila virescens, while NCBI and iNaturalist maintain it as Temnoscheila virescens. The spelling variation (Temnoscheila vs. Temnochila) reflects historical taxonomic uncertainty.
