Agrilus cochisei

Adults are small, slender beetles typical of the genus Agrilus, with metallic coloration characteristic of Buprestidae. Specific diagnostic features distinguishing A. cochisei from congeners are not documented in available sources.

Associated with Ambrosia psilostachya (western ragweed) in open, arid environments. Observed in western Texas in sandy or rocky areas with sparse vegetation.

Central America and North America. Specifically documented from western Texas (Toyahyale area, Davis Mountains region).

Adults active in late April to May in western Texas. Peak activity appears to occur in early to mid-May based on collection records, though adults have been found in late April during early season collecting.

Adults feed on Ambrosia psilostachya (western ragweed); observed feeding on flowers of Sphaeralcea sp.

• Ambrosia psilostachya - adult feeding hostwestern ragweed; adults swept abundantly from this plant
• Sphaeralcea sp. - adult feeding hostadults observed on flowers

Adults are readily swept from host vegetation. Mating pairs have been observed on host plants. Adults appear to be diurnal and associated with low-growing herbaceous vegetation rather than woody plants.

• Agrilus obtususBoth are small Agrilus species found in western Texas on herbaceous hosts; A. obtusus occurs on Senna roemeriana rather than Ambrosia
• undescribed Acmaeodera sp.Found sympatrically in western Texas and collected using similar sweeping techniques on flowers, but belongs to different genus with distinct body form
