Pachybrachis atomarius
Pachybrachis atomarius is a species of case-bearing leaf beetle in the family Chrysomelidae, distributed across North America. The genus Pachybrachis comprises small leaf beetles that carry their eggs and larvae in protective cases constructed from fecal material. This species has been documented in Canada (Alberta, Manitoba, Nova Scotia) and presumably occurs throughout much of the United States given the broad North American distribution reported.
Pachybrachis caelatus

As a recently described species, detailed natural history information remains limited.

The species has been documented in the southwestern United States, particularly in Arizona, where it has been collected at light stations in mesquite-acacia scrub and oak-juniper woodland habitats. Like other members of the genus Pachybrachis, it is likely associated with woody vegetation, though specific host plant relationships remain poorly documented.
Pachybrachis latithorax
Tamaulipan Freckled Pachy
Pachybrachis latithorax is a species of case-bearing leaf beetle in the family Chrysomelidae. It occurs in Central America and North America. The species belongs to a genus commonly known as 'scriptured leaf beetles' for their often intricate elytral patterns. Like other members of Pachybrachis, it is presumed to feed on foliage of various plants, though specific host associations remain poorly documented.
Pachybrachis m-nigrum
Pachybrachis m-nigrum is a species of case-bearing leaf beetle in the family Chrysomelidae, first described by Melsheimer in 1847. The specific epithet 'm-nigrum' refers to a distinctive black marking shaped like the letter 'M' on the elytra. Like other members of the genus Pachybrachis, it constructs protective cases from fecal material. The species is documented from eastern Canada and has been recorded in the southwestern United States.
Pachybrachis marmoratus
Pachybrachis marmoratus is a species of case-bearing leaf beetle in the family Chrysomelidae. The genus Pachybrachis comprises small, convex beetles that construct protective cases from fecal material and shed exuviae, a trait shared with other members of the subfamily Cryptocephalinae. This species occurs in both Central America and North America.
Pachybrachis nigricornis
Pachybrachis nigricornis is a species of case-bearing leaf beetle in the family Chrysomelidae, originally described by Thomas Say in 1824 as Cryptocephalus nigricornis. The species is distributed across North America and Central America, with records from Canada (Alberta) through the United States. It belongs to a large genus of small, often colorful leaf beetles commonly known as 'scriptured leaf beetles' due to their intricate elytral patterns. Four subspecies are currently recognized.
