Acmaeodera adenostomae

Cazier, 1938

Acmaeodera adenostomae is a small jewel beetle (Buprestidae) described by Cazier in 1938. It belongs to the large and taxonomically challenging Acmaeodera, which contains over 150 in North America. The species epithet 'adenostomae' suggests an association with the plant genus Adenostoma, though specific biological details remain poorly documented. Like many western North American Acmaeodera, it likely occurs in arid or semi-arid . The genus is characterized by flower-visiting and wood-boring larvae, but species-level for A. adenostomae has not been specifically recorded.

Taxonomic Note

The specific epithet 'adenostomae' strongly implies a plant association with Adenostoma (Rosaceae), a of shrubs native to California and northern Baja California. This would be consistent with patterns seen in other Acmaeodera , where epithets often reflect documented host relationships. However, no published host records or biological observations confirming this association were found in the provided sources.

Genus Context

Acmaeodera is one of the largest of jewel beetles in North America and is in critical need of taxonomic revision. Many , including potentially A. adenostomae, are difficult to identify without comparison to or determined material. The genus is characterized by that visit flowers for pollen feeding and larvae that bore in woody branches of various plants.
