Definition
Copestylum caudatum is a purported scientific name that appears to refer to a species within the genus Copestylum, a group of hoverflies in the family Syrphidae. No reliable, peer‑reviewed sources or major taxonomic databases currently confirm the existence or formal description of this specific epithet.
Overview
The genus Copestylum comprises a diverse assemblage of neotropical and Nearctic hoverflies, many of which are associated with decaying cactus tissue or other saprophagous habitats. While numerous species have been formally described, the name Copestylum caudatum does not appear in standard references such as the World Catalog of Syrphidae (Thompson et al., 1976), the Integrated Taxonomic Information System (ITIS), or recent entomological publications.
Etymology / Origin
The specific epithet caudatum derives from Latin caudatus, meaning “tailed” or “having a tail”. In zoological nomenclature, such an epithet is often applied to species exhibiting a distinct posterior morphological feature, such as an elongated abdomen or a tail‑like appendage. If the name were valid, it would likely reference a characteristic tail‑like structure in the adult fly.
Characteristics
Accurate morphological or ecological characteristics of Copestylum caudatum cannot be provided, as the taxon lacks verified description. General traits of Copestylum species include:
- Medium‑sized hoverflies (5–15 mm in length).
- Often brightly colored or metallic bodies.
- Larvae typically saprophagous, developing in decaying plant material, especially cactus necrosis.
Without a formal description, it is uncertain whether C. caudatum conforms to these general patterns or possesses unique diagnostic features.

Note
Accurate information about Copestylum caudatum is not confirmed in available scientific literature or authoritative taxonomic databases. Consequently, the entry is limited to tentative etymological interpretation and contextual discussion based on the broader genus.
