Definition
Methia lineata is a species of beetle within the family Cerambycidae, commonly known as longhorn beetles.
Overview
The species belongs to the genus Methia, which comprises small to medium‑sized cerambycids characterized by relatively short antennae compared with many other longhorn beetles. M. lineata has been listed in several taxonomic catalogs of North American Cerambycidae, including photographic compilations by Larry G. Bezark. The precise geographic range is not thoroughly documented in readily accessible literature, but the genus Methia is primarily distributed in the New World, particularly in the United States and adjacent regions. The species authority (the taxonomist who first described the species) and year of description are not consistently cited in the sources consulted; therefore, that information remains uncertain.
Etymology / Origin
The specific epithet lineata derives from the Latin word lineatus, meaning “lined” or “striped.” Such a name typically refers to the presence of linear markings on the dorsal surface of the beetle, a trait observed in many members of the genus.
Characteristics
While detailed morphological data for M. lineata are limited, members of the genus Methia generally share the following features:
- Body shape: Elongated and somewhat cylindrical, ranging from 5 to 15 mm in length.
- Antennae: Moderately long, usually not exceeding the body length, with segments that may be subtly serrate.
- Coloration: Often brownish or reddish, with distinctive longitudinal lines or stripes that give the species its name.
- Pronotum: Typically smooth or lightly punctate, lacking prominent spines.
- Elytra: Hardened forewings that cover the abdomen, frequently displaying the linear markings referenced by the epithet.
Life history specifics—such as host plants, larval development, and adult phenology—are not well documented for M. lineata. In related Methia species, larvae commonly bore into dead or dying woody material, and adults are often found on flowers or vegetation during the warmer months.

Note on Information Availability
Accurate, detailed information on Methia lineata—including its original description, precise distribution, and comprehensive morphological data—is not fully confirmed in publicly accessible, peer‑reviewed sources. Further research in specialized taxonomic revisions or museum specimen records would be required to provide a more exhaustive account.
