Xanthonia hirsuta

Distinguished from other Xanthonia species by the presence of dense, conspicuous body setae. Identification to species level requires examination of genitalic characters and comparison with type specimens. The species was formally described in 2019, making it one of the more recently recognized members of the genus.

Associated with juniper vegetation, based on the common name 'Small Juniper Xanthonian'. Likely inhabits coniferous woodlands and scrublands where juniper species occur.

Distribution data limited due to recent description. Observations recorded on iNaturalist suggest occurrence in North America, but specific range boundaries remain poorly documented.

Likely folivorous on juniper (Juniperus) or related Cupressaceae, based on genus-level associations and common name. Specific feeding records have not been published.

• Juniperus - probable food plantInferred from common name; not confirmed by published host records

As a leaf beetle, likely functions as a primary consumer in coniferous ecosystems, contributing to nutrient cycling through folivory.
