"Apparently a generalist: BugGuide images show this species eating flowers of spring beauty (
Claytonia caroliniana) and foliage of white ash (
Fraxinus americana) and Amur honeysuckle (
Lonicera maackii)." (Charley's comment moved from
C. thyamoides page, rendered inapplicable there as a result of the latest developments. =v=)) Clark et al.
(3) report having found this species feeding on the bracts at the bases of flowering dogwood (Cornaceae:
Cornus florida) flower clusters, and on (presumably foliage of) possumhaw (Aquifoliaceae:
Ilex decidua), trumpet creeper (Bignoniaceae:
Campsis radicans), common dittany (Lamiaceae:
Cunila origanoides), ash (Oleaceae:
Fraxinus spp.), smooth yellow false foxglove (Scrophulariaceae:
Aureolaria flava), and mullein foxglove (Scrophulariaceae:
Dasistoma macrophylla). They list honeysuckle and snowberry among the many other plants these beetles have been found on, but the
BugGuide record (assuming the beetle is correctly identified) may be the first documentation of actual feeding on a member of the honeysuckle family (Caprifoliaceae).
