Horn, 1886
Chrysobothris axillaris is a North American jewel beetle in the Buprestidae. The was described by Horn in 1886. Based on field observations in the Davis Mountains of Texas, have been collected from Quercus grisea (gray oak) with fresh foliage, suggesting an association with oak . The species appears to be active in late spring to early summer.

Identification
Chrysobothris axillaris belongs to the C. femorata group. It can be distinguished from similar Chrysobothris species by specific morphological features, though detailed diagnostic characters require specimen examination. Within its range, it may be confused with C. caddo and other members of the femorata group; accurate identification typically requires reference to original descriptions or keys.
Habitat
Oak-juniper woodland and montane oak . In the Davis Mountains of Texas, have been collected from Quercus grisea (gray oak) in areas with fresh spring foliage, at elevations where gray oak occurs.
Distribution
North America. Documented from the Davis Mountains in Jeff Davis County, Texas. The GBIF match indicates presence in North America broadly.
Seasonality
Late spring to early summer. have been observed active in early June in the Davis Mountains of Texas.
Host Associations
- Quercus grisea - association collected from trees with fresh spring foliage; larval unconfirmed
Behavior
have been observed on oak foliage and are likely arboreal. Based on related Chrysobothris , adults may be active on sunny days and capable of rapid when disturbed.
Similar Taxa
- Chrysobothris caddoSimilar size and appearance within the C. femorata group; both occur in Texas oak
- Chrysobothris femorataType of the species group; morphological similarities require careful differentiation
More Details
Collection method
In the Davis Mountains, were successfully collected using a long-handled aerial net to sweep upper branches of Quercus grisea, a technique that accesses foliage beyond the reach of standard beating sheets.
Taxonomic context
The C. femorata group contains multiple similar species, and accurate identification of C. axillaris often requires examination of or reference to Horn's original 1886 description.
