Acmaeoderopsis rockefelleri

Acmaeoderopsis rockefelleri can be distinguished from congeners by its small size and vittate (striped) elytral pattern. It belongs to a genus of tiny buprestids that are challenging to collect due to their rapid flight upon disturbance. Field observations indicate adults are extremely active and difficult to capture by standard beating techniques, with aerial netting of flying individuals proving more effective.

Arid and semi-arid regions including sand dune ecosystems and desert scrub. Associated with mesquite (Prosopis glandulosa) and soapberry (Sapindus drummondii) vegetation in western Texas and southeastern New Mexico.

Recorded from the southwestern United States (Texas, New Mexico) and Mexico. GBIF records indicate presence in the Nearctic and Neotropic regions.

Adults have been collected in June, suggesting peak activity during early summer following rainfall events that trigger insect emergence in arid habitats.

• Prosopis glandulosa - adult associationAdults collected by beating mesquite; also observed flying to branch tips
• Prosopis juliflora - adult associationRecorded host from literature
• Acacia constricta - adult associationRecorded host from literature
• Sapindus drummondii - habitat associationFound in same habitat matrix, though primary association appears to be with Prosopis

Adults are diurnal and highly active, flying immediately upon disturbance. They have been observed flying to the tips of high mesquite branches, making collection difficult by conventional beating methods. Aerial netting while adults are in flight has proven more successful than beating.

• Acmaeoderopsis prosopisSimilar size, habitat, and host association with Prosopis; distinguished by subtle differences in elytral sculpture and coloration pattern
• Acmaeodera quadrivittatoidesSimilar small size and vittate pattern; Acmaeoderopsis species are generally smaller and more slender than Acmaeodera, with faster escape flight
• Acmaeodera mixtaSympatric and syntopic in sand dune habitats; Acmaeoderopsis distinguished by smaller size and more rapid, erratic flight behavior
