Metrioidea atriceps
(Horn, 1893)
Metrioidea atriceps is a of skeletonizing leaf beetle in the Chrysomelidae. It is found in North America. As a member of the tribe Alticini (flea beetles), it likely possesses enlarged hind adapted for jumping, though specific behavioral observations for this species are limited. The species was described by Horn in 1893.

Identification
Identification to level requires examination of morphological characters such as male genitalia and detailed body proportions. The species can be distinguished from other Metrioidea species by subtle differences in coloration (suggested by the species epithet 'atriceps,' meaning 'black-headed'). Expert determination is recommended.
Appearance
As a skeletonizing leaf beetle, M. atriceps likely has the compact body form typical of Galerucinae. Members of the Metrioidea are generally small beetles. Specific coloration and morphological details for M. atriceps are not well documented in available sources.
Distribution
North America. Specific range boundaries within North America are not well documented.
Ecological Role
As a skeletonizing leaf beetle, M. atriceps likely feeds on leaf tissue between leaf , leaving a characteristic lace-like pattern. This feeding damage is typical of Galerucinae larvae and , though specific plant interactions for this are not documented.
Similar Taxa
- Other Metrioidea speciesCongeneric share similar body plans and require detailed morphological examination for separation, particularly of male genitalia and coloration patterns.
- Other Alticini (flea beetles)Members of this tribe share the enlarged hind for jumping and similar body proportions; identification requires examination of specific morphological characters.

Taxonomic note
The epithet 'atriceps' (black-headed) suggests distinctive coloration that may aid in identification, though this has not been explicitly documented in the examined sources.
