Baconia venusta
(LeConte, J. E., 1845)
clown beetle
Baconia venusta is a of clown beetle in the Histeridae, described by John Lawrence LeConte in 1845. The Baconia is renowned for brilliant coloration and bizarrely flattened body forms, with species exhibiting jewel-like metallic hues that are rare in the Histeridae family. Species in this genus are believed to be of wood-boring beetles and their larvae, with some attracted to bark beetle . B. venusta is one of approximately 116 species in the genus, most of which were described in a 2013 systematic revision.

Identification
-level identification of Baconia venusta requires examination and comparison with . The is distinguished from other Histeridae by the combination of brilliant metallic coloration and strongly flattened body form. Within Baconia, species are differentiated by subtle morphological characters including body proportions, punctuation patterns, and genitalic structures. Nearly half of all Baconia species are known from only one or two specimens, suggesting extreme rarity and making field identification challenging.
Habitat
Baconia are associated with recently killed trees where they pursue prey under bark. Specific microhabitat preferences for B. venusta are not documented.
Distribution
Found in North America; specific range within North America not detailed in available sources. The Baconia occurs primarily in North and South America.
Diet
Believed to prey on wood-boring beetles and their larvae, including bark beetles (Scolytinae). Some Baconia are attracted to bark beetle , which they may use to locate prey.
Life Cycle
Complete with , larva, pupa, and stages. Specific details for B. venusta are not documented.
Behavior
Predatory targeting wood-boring beetles under bark. Some Baconia are drawn to of bark beetles, potentially using these chemical cues to locate prey.
Ecological Role
of wood-boring beetles; likely contributes to regulation of bark beetle in forest .

Taxonomic history
The Baconia was originally named in honor of Francis Bacon, the Elizabethan philosopher. A 2013 systematic revision by Michael Caterino and Alexey Tishechkin described 85 new , bringing the genus total to 116 species. Most species are known from extremely few specimens—nearly half from only one or two specimens—indicating that these beetles remain poorly collected and likely genuinely rare.
Research significance
The 2013 revision of Baconia was part of a large- study of clown beetle diversity funded by the U.S. National Science Foundation. The study highlighted how even well-known contain neglected groups with extraordinary, poorly understood diversity.
