Camponotus ulcerosus

Wheeler, 1910

Camponotus ulcerosus is a of carpenter ant in the Camponotus, described by Wheeler in 1910. It is native to the southwestern United States and Mexico. As a member of the carpenter ant group, it nests in wood and exhibits the typical colony structure of the genus with polymorphic . Beyond its geographic range and taxonomic placement, specific biological details remain poorly documented in published literature.

Appearance

As a Camponotus , likely exhibit the -typical features: polymorphic size classes ranging from minor to major workers, a smooth thoracic profile without a distinct metanotal depression, and a single-segmented petiole (-waist). The specific epithet "ulcerosus" may refer to distinctive cuticular features, though original type description details are not provided in available sources. Coloration and specific morphological diagnostics for this species versus in its range are not documented in the provided context.

Habitat

Nesting habits are not explicitly documented, but as a carpenter ant, it likely occupies dead wood in natural or semi-natural environments. Specific moisture requirements, preferred wood types, and nesting substrates remain unreported.

Distribution

Native to Mexico, Texas, New Mexico, and Arizona in the southwestern United States and adjacent Mexico.

Taxonomic note

The was described by William Morton Wheeler in 1910. Wheeler was a prominent myrmecologist who described numerous Camponotus species from the Americas. The specific epithet "ulcerosus" is Latin-derived, possibly referring to blister-like or ulcerous cuticular structures, though this interpretation requires verification from the original description.

Data gaps

Despite being described over a century ago, C. ulcerosus appears poorly represented in ecological and behavioral literature. Available sources provide only geographic range and taxonomic placement without details on nesting , colony structure, foraging , or ecological interactions.
