Pachybrachis pectoralis
A case-bearing leaf beetle in the family Chrysomelidae, first described by Melsheimer in 1847. It is one of numerous small, rounded leaf beetles in the genus Pachybrachis, commonly referred to as script-bearing leaf beetles due to the often intricate markings on their elytra. The species occurs in North America, with records from Canada (Ontario, Québec) and the United States. Like other members of its genus, it likely feeds on various herbaceous plants and shrubs.
Pachybrachis postfasciatus
Pachybrachis postfasciatus is a species of case-bearing leaf beetle described by Fall in 1915. It belongs to the family Chrysomelidae, a large group of herbivorous beetles commonly known as leaf beetles. The species is documented from North America. Like other members of the genus Pachybrachis, it is likely associated with vegetation in its habitat, though specific ecological details remain poorly documented.
Pachybrachis signatifrons
Pachybrachis signatifrons is a species of case-bearing leaf beetle in the family Chrysomelidae. It is found in North America. The species was described by Mannerheim in 1843. Like other members of its genus, it belongs to the subfamily Cryptocephalinae, which are characterized by larvae that construct and carry protective cases.
Pachybrachis signatus
Pachybrachis signatus is a species of case-bearing leaf beetle in the family Chrysomelidae. It is a small beetle within the diverse genus Pachybrachis, which comprises numerous North American species often difficult to distinguish without close examination. The species was described by Bowditch in 1909. Available records indicate it occurs in North America, though specific ecological details remain poorly documented.
Pachybrachis snowi
Pachybrachis snowi is a species of case-bearing leaf beetle in the family Chrysomelidae. It is native to North America. The species was described by Bowditch in 1909. Beyond its taxonomic placement and geographic occurrence, detailed biological information about this species remains limited in available sources.
Pachybrachis sonorensis
Finely-punctate Sonoran Pachy
Pachybrachis sonorensis is a species of case-bearing leaf beetle in the family Chrysomelidae, described by Jacoby in 1889. It is native to North America, with records from the southwestern United States and adjacent regions. The species belongs to a large genus of small leaf beetles characterized by their rounded, convex body form and enlarged hind femora.
Pachybrachis subfasciatus
Pachybrachis subfasciatus is a species of case-bearing leaf beetle in the family Chrysomelidae. It is a small beetle native to North America, with records from Canada (Manitoba, Ontario) and the United States. The species is part of the diverse genus Pachybrachis, which contains numerous similar-looking species that are often difficult to distinguish without close examination.
Pachybrachis tacitus
A small leaf beetle in the family Chrysomelidae, described by Fall in 1915. Like other members of the genus Pachybrachis, this species is part of a diverse group of case-bearing leaf beetles found in North America. The species is documented from limited collection records, with observations spanning the southwestern United States.
Pachybrachis texanus
Tall Texas Pachy
Pachybrachis texanus is a species of case-bearing leaf beetle in the family Chrysomelidae. It is found in Central America and North America. The species is relatively poorly documented, with approximately 80 observations recorded on iNaturalist. It belongs to a genus of small leaf beetles known for their rounded, convex body form and often colorful or patterned elytra.
Pachybrachis trinotatus
Pachybrachis trinotatus is a species of case-bearing leaf beetle in the family Chrysomelidae, first described by Melsheimer in 1847. The species is distributed across North America, with records from Canada (Ontario and Québec) and the United States. As a member of the genus Pachybrachis, it belongs to a group commonly known as scriptured leaf beetles, characterized by their compact bodies and often patterned elytra. Specific ecological details about this species remain limited in published literature.
Pachybrachis turgidicollis
Pachybrachis turgidicollis is a species of case-bearing leaf beetle in the family Chrysomelidae. It has been documented in North America, specifically recorded from Arizona and Texas. The species was described by Fall in 1915. Like other members of the genus, it belongs to the tribe Pachybrachini, which are known for their compact bodies and enlarged hind femora.
Pachybrachis vulnerosus
A species of case-bearing leaf beetle in the family Chrysomelidae, described by Fall in 1915. It belongs to the tribe Pachybrachini, a group known for their hardened, case-like elytra that protect the abdomen. The species is found in North America, with specific records from the southwestern United States including Arizona.
Pachybrachis xanti
Split-neck Creosote Pachy
Pachybrachis xanti is a case-bearing leaf beetle in the family Chrysomelidae. The species is commonly known as the "Split-neck Creosote Pachy" and has been documented in North America and Middle America. Like other members of the genus Pachybrachis, it carries a protective case constructed from fecal material and exuviae.
Saxinis sonorensis
Saxinis sonorensis is a species of case-bearing leaf beetle in the family Chrysomelidae. It was described by Jacoby in 1889. The species occurs in Central America and North America, with two recognized subspecies: S. s. scutellaris (Schaeffer, 1906) and S. s. sonorensis (Jacoby, 1889). As a member of the case-bearing leaf beetles, larvae construct protective cases from fecal material and plant debris.
Smaragdina militaris
Texas Military Leaf Beetle
Smaragdina militaris is a species of case-bearing leaf beetle in the family Chrysomelidae. It is found in North America. Two subspecies are recognized: S. m. arizonica and the nominate S. m. militaris. As a member of the case-bearing leaf beetles, it likely exhibits the family's characteristic behavior of constructing protective cases from fecal material and shed exoskeletons.
