Agrilus abditus
Horn, 1891
Agrilus abditus is a North American jewel beetle ( Buprestidae) described by George Henry Horn in 1891. The belongs to the hyperdiverse Agrilus, which contains thousands of species worldwide. Based on field observations, have been collected by sweeping foliage of Quercus arizonica (Arizona white oak) in southeastern Arizona. The species appears to be associated with oak in montane regions of the southwestern United States.

Identification
of Agrilus abditus can be distinguished from similar Agrilus by examination of elytral , coloration, and genitalic structure. Accurate identification typically requires comparison with or reference collections. The species is smaller than many and lacks the prominent elytral vittae seen in some other oak-associated Agrilus.
Habitat
Oak-juniper woodland and montane oak forests. Specifically associated with Quercus arizonica (Arizona white oak) in the Huachuca Mountains of southeastern Arizona.
Distribution
Documented from the Huachuca Mountains in Cochise County, southeastern Arizona. The likely occurs more broadly in oak woodlands of the southwestern United States and adjacent Mexico, though records remain sparse.
Seasonality
have been observed in late May to early June in southeastern Arizona, suggesting spring coinciding with new oak foliage flush.
Host Associations
- Quercus arizonica - collected by sweeping foliage; larval presumed but not confirmed.Arizona white oak in Huachuca Mountains, Cochise County, Arizona.
Behavior
have been observed on oak foliage and are likely arboreal, consistent with other Agrilus . Sweeping upper branches with extended-handled nets has proven effective for collecting this species.
Ecological Role
As a member of the Buprestidae, larvae likely function as wood-borers in oak branches or trunks, contributing to nutrient cycling and creating for other organisms.
Human Relevance
Of interest to entomologists and biodiversity researchers. No known economic importance.
