Brachys barberi
Fisher, 1924
Brachys barberi is a small metallic wood-boring beetle in the Buprestidae. The is associated with oak , particularly Quercus havardii (shin oak), and has been collected from sand dune in the southwestern United States. are active during spring and early summer, with observations and collections spanning from May to June. The species is part of the Brachys, a group of oak-associated buprestids that are typically collected by sweeping or beating foliage of host trees.

Identification
Brachys barberi is a small buprestid that can be distinguished from similar by its association with Quercus havardii (shin oak) in sand dune . It is smaller than many related Brachys species and has been noted as difficult to distinguish from the more common eastern species B. ovatus, requiring careful examination of collected specimens. The species is typically found in the depressions of sand dunes where shin oak grows, rather than on ridge-top plants.
Habitat
Sand dune , specifically in association with Quercus havardii (shin oak) growing in depressions between dunes. The has been collected from the Mescalero Sands area in New Mexico and similar sandhill .
Distribution
North America, specifically recorded from New Mexico (Mescalero Sands Recreation Area, Chaves County) and potentially adjacent areas with suitable sand dune and shin oak . The distribution appears restricted to sand dune systems in the southwestern United States.
Seasonality
have been observed and collected from mid-May through early June. Activity coincides with the period when shin oak foliage is fresh and developing, which appears to be a key factor in adult presence.
Diet
Larval development occurs in oak (Quercus havardii). have been observed on oak foliage and may feed on foliage or be attracted to volatiles.
Host Associations
- Quercus havardii - larval shin oak; larvae develop in living branches
Behavior
are active during daylight hours and have been collected by sweeping stands of shin oak with aerial nets. They are most readily found in depressions of sand dunes where shin oak grows, rather than on plants growing on upper slopes or ridge tops. The has been observed flying to branch tips when disturbed.
Similar Taxa
- Brachys ovatusSimilar appearance; B. barberi was initially mistaken for this more common eastern in field collections from western Oklahoma, requiring subsequent specimen examination to confirm identity
- Brachys querciAnother oak-associated Brachys found in similar ; distinguished by preference and geographic range
- Brachys rileyiSimilar small size and oak association; B. rileyi occurs on Quercus gambelii at higher elevations rather than Q. havardii in sand dunes
