Linsleya convexa
(LeConte, 1853)
Linsleya convexa is a blister beetle in the Meloidae, subgenus Linsleya. The was described by LeConte in 1853 and is native to western North America. It belongs to a of moderate-sized meloids associated with grassland and prairie . Like other members of the Epicautini tribe, it possesses chemical defenses derived from .

Identification
The is placed in the subgenus Linsleya (Linsleya), distinguishing it from members of the subgenus Linsleyina. Separation from the closely related L. suavissima and other congeneric species requires examination of male genitalia and subtle differences in antennal structure and body proportions. The convex body form implied by the species name may aid in field recognition, though this character requires verification.
Appearance
Moderate-sized blister beetle. Specific coloration and body form details are not documented in available sources, though the epithet 'convexa' suggests a convex body shape.
Habitat
Shortgrass prairie and grassland . The has been photographed in canyon environments with flowering vegetation, suggesting association with open, dry landscapes supporting herbaceous plant .
Distribution
Western North America. The has been documented in Colorado and Oklahoma. GBIF records indicate presence in Middle America and North America broadly, though specific country records beyond the United States are not confirmed.
Seasonality
have been observed in summer months. A specimen was photographed at sunset in early July near Vogel Canyon, Colorado, suggesting peak adult activity during mid-summer.
Behavior
have been observed on flowers, a common among Epicautini blister beetles. The is likely given its flower-visiting habits.
Ecological Role
As a member of Meloidae, the likely participates in pollination while feeding on floral resources. Its larvae are presumed to be or parasitic on ground-nesting bees or pods, following the typical pattern of Epicautini.
Human Relevance
Like other blister beetles, L. convexa produces and may pose a risk to livestock if consumed in contaminated hay. However, specific documentation of economic impact is lacking.
Similar Taxa
- Linsleya suavissimaClosely related in the same subgenus, distinguished by subtle differences in antennal structure and male genitalia. Both species occur in western grasslands.
- Linsleya californicaMember of subgenus Linsleyina rather than Linsleya; can be separated by subgeneric characters and geographic distribution.
- Epicauta speciesLarger, more commonly encountered members of the same tribe; Linsleya are generally smaller and less conspicuously colored.
More Details
Taxonomic History
The was originally described by John Lawrence LeConte in 1853. The Linsleya was established to accommodate species previously placed in Epicauta that share distinctive morphological features, particularly in male genitalia structure. The subgenus Linsleya (Linsleya) contains L. convexa and L. suavissima, while the subgenus Linsleyina contains four additional species.
Collection Records
The Entomology Research Museum at the University of California, Riverside holds 13 specimens of this as of 2010, indicating it is represented in collections but not among the most commonly collected meloids.
Photographic Documentation
A published photograph by Ted MacRae from Vogel Canyon, Colorado shows the on flowers at sunset, providing one of the few documented field images of this relatively obscure species.
