Habitat
Dry, open with flowering vegetation. In Texas, collected from roadside areas with abundant flowers in bloom.
Distribution
Central America and North America. Specifically documented from Val Verde County, Texas, USA. The name suggests a relationship to or distinction from A. disjuncta, which may indicate a southwestern U.S. and Mexican distribution pattern.
Seasonality
Active in late spring. Documented from field observations on May 17, 2022, in Texas.
Diet
feed on pollen from flowers. Documented visiting flowers of Wedelia hispida (Texas creeping-oxeye) and Thelosperma simplicifolium (slender greenthread).
Host Associations
- Wedelia hispida - food source collected on flowers
- Thelosperma simplicifolium - food source collected on flowers along with other Acmaeodera
Behavior
are flower visitors. Readily attracted to yellow composite flowers. Collected alongside other Acmaeodera including A. mixta, A. neoneglecta, A. starrae, and A. ornatoides, suggesting shared preferences and flower-visiting .
Ecological Role
Pollen-feeding beetles may contribute to pollination of flowers. Larval stage likely develops in woody plant material, as is typical for the Buprestidae, though specific host plants for larval development are not documented.
