Chrysobothris mescalero
Wellso & Manley, 2007
Chrysobothris mescalero is a metallic wood-boring beetle in the Buprestidae, described in 2007 by Wellso and Manley. It belongs to the taxonomically challenging Chrysobothris femorata -group. The species is to sand dune in New Mexico and west Texas, where it develops exclusively in oak (Quercus) species. are characterized by uniformly brown and in both sexes, and three distinct elytral with indistinct foveae.

Identification
Distinguished from other Chrysobothris femorata -group members by the combination of: (1) uniformly brown and in both sexes (shared only with C. seminole), (2) three distinct elytral versus two indistinct costae in C. seminole, (3) indistinct elytral foveae versus distinct foveae in C. seminole, and (4) southwestern distribution with oak association versus southeastern distribution with woody goldenrod host in C. seminole. Identification requires examination of these subtle morphological characters as no single diagnostic trait exists.
Habitat
Sand dune systems and associated scrub vegetation in arid regions of New Mexico and west Texas. Specifically associated with Quercus havardii (shin oak) and other oak growing in sandy substrates.
Distribution
New Mexico and west Texas, United States. Records from Monahans Sandhills area and similar sand dune in the region.
Seasonality
active in spring; observed in late April to early May based on collecting records. Exact poorly documented due to limited collection data.
Host Associations
- Quercus havardii - larval Shin oak; larvae develop in flagged (dead) branches
- Quercus - larval -level association; specific oak may vary
Life Cycle
Larval development occurs within branches of living oaks, particularly in flagged (dead) branch portions. emerge from these branches. Specific details of -laying, larval instars, , and adult longevity are not documented.
Behavior
have been observed on oak foliage. Larvae are wood-borers creating galleries in oak sapwood. No specific behavioral observations beyond association are recorded.
Ecological Role
Primary consumer as larva, developing in living oak tissue; contributes to nutrient cycling through wood decomposition. Specific ecological impacts or interactions with other organisms are not documented.
Human Relevance
No documented economic or agricultural significance. Primarily of interest to coleopterists and taxonomists due to its recent description and restricted distribution. Not known to be a pest of ornamental or fruit trees unlike some .
Similar Taxa
- Chrysobothris seminoleShares uniformly brown and in both sexes, but distinguished by two indistinct elytral with distinct foveae, southeastern distribution (Georgia/Florida), and exclusive association with woody goldenrod (Chrysoma pauciflosculosa) rather than oak
- Chrysobothris femorataHistorically confused with this before 2007 revision; distinguished by straight posteriolateral elytral margins, reddish elytral tips, and broader range including many hardwoods
- Chrysobothris comancheAnother member of femorata -group from southwestern US; distinguished by lack of cross- on and indistinct foveae, and exclusive association with Juglans

Taxonomic History
Described by Wellso and Manley in 2007 as part of their revision of the Chrysobothris femorata -group, which doubled the number of recognized species in this complex. The revision clarified species boundaries that had been obscured for decades, with many specimens previously identified as C. femorata now assignable to distinct species with specific and geographic associations.
Collecting Methodology
Best collected by locating flagged (dead) branches on living oaks in sand dune , cutting these branches, and rearing in cages. Direct observation of adults on foliage is possible but beetles are reportedly elusive and easily overlooked.
