Cryptocephalinae Lamprosomatinae Camptosomata are the case-bearing leaf beetles or camptosomates, named for their larval habit of carrying a case of waste material.

This group consists of two subfamilies of Chrysomelidae (leaf beetles): Lamprosomatinae and Cryptocephalinae (which include the former Chlamisinae and Clytrinae).

[1][2][3] Each case begins as a wrapping that the mother creates by laying plates of fecal material around each egg.

Larval camptosomates add to and expand this case with their own waste materials as they grow.

When they metamorphose into adults, these beetles then cut a circle around the apex of the case, pop off the cap, and crawl out, ready to feed, mate, and start the cycle over again.
