Species Guides
4Coleorozena is a of case-bearing leaf beetles in the Chrysomelidae, containing seven described . The genus was established by Moldenke in 1970, primarily to accommodate species originally described in the genus Coscinoptera. Taxonomic treatment of this group has varied, with some authorities suggesting reintegration into Coscinoptera, though recent revisions maintain Coleorozena as a separate genus.

Distribution
of Coleorozena are recorded from North America, with distributions spanning the United States and adjacent regions. Specific range data varies by species: C. vittata and C. lecontii have broad distributions, while others such as C. alicula and C. subnigra appear more restricted.
Life Cycle
As case-bearing leaf beetles, larvae construct portable cases from fecal material and shed , a characteristic trait of the Cryptocephalinae. Larval development occurs within these cases, which are carried throughout the mobile larval stage.
