Guides
Androlyperus incisus
Androlyperus incisus is a skeletonizing leaf beetle in the family Chrysomelidae, first described by Schaeffer in 1906. The species is distributed across Central America and North America. It belongs to a genus of leaf beetles whose members feed on plant foliage, creating distinctive skeletonized damage patterns. Observations of this species remain relatively sparse, with limited published documentation of its biology.
Araeoderes texanus
Araeoderes texanus is a species of fungus weevil in the family Anthribidae, described by Schaeffer in 1906. The species is provisionally accepted in taxonomic databases and is known from North America. As a member of the Anthribidae, it belongs to a group of weevils commonly known as fungus weevils, though specific details about its biology and ecology remain poorly documented in available literature.
Brachypnoea rotundicollis
Brachypnoea rotundicollis is a leaf beetle species in the family Chrysomelidae. It was described by American entomologist Charles Frederic August Schaeffer in 1906. The species has a restricted distribution in southeastern Texas, with only 11 documented observations. Little is known about its biology or ecology beyond basic taxonomic and distributional records.
Conotrachelus tuberculicollis
Conotrachelus tuberculicollis is a species of true weevil in the family Curculionidae, described by Schaeffer in 1906. It is native to North America. As a member of the genus Conotrachelus, it shares the characteristic elongated snout typical of weevils in this group. Information specific to this species is limited in available sources.
Coscinocephalus
Coscinocephalus is a genus of rhinoceros beetles in the family Scarabaeidae, established by Prell in 1936. The genus comprises at least two described species: Coscinocephalus cribrifrons, described by Schaeffer in 1906, and Coscinocephalus tepehuanus, described by Morón & Ratcliffe in 1996. Members of this genus belong to the subfamily Dynastinae and tribe Pentodontini, placing them among the smaller rhinoceros beetles.
Coscinocephalus cribrifrons
Coscinocephalus cribrifrons is a rhinoceros beetle in the subfamily Dynastinae. The species was described by Schaeffer in 1906. It occurs in the southwestern United States and northern Mexico. Like other dynastine beetles, it possesses enlarged cephalic or thoracic horns, though specific horn morphology for this species is not well documented.
Cryptocephalus duryi
Tamaulipan Freckled Cryptocephalus
Cryptocephalus duryi is a case-bearing leaf beetle in the family Chrysomelidae, first described by Schaeffer in 1906. It is known from North America, with iNaturalist records documenting 17 observations. The species belongs to a genus of leaf beetles characterized by larvae that construct portable cases from fecal material and shed skins.
Cryptocephalus simulans
case-bearing leaf beetle
Cryptocephalus simulans is a species of case-bearing leaf beetle in the family Chrysomelidae. It is found in North America. The species was described by Schaeffer in 1906 and includes four recognized subspecies. Like other members of the genus, adults are associated with vegetation and larvae construct protective cases from excrement and shed skins.
Cryptocephalus umbonatus
Cryptocephalus umbonatus is a case-bearing leaf beetle in the family Chrysomelidae, described by Schaeffer in 1906. It is found in North America. Like other members of its genus, it belongs to a group commonly known as case-bearing leaf beetles due to the habit of larvae constructing protective cases from fecal material and exuviae.
Ormiscus quercus
Ormiscus quercus is a species of fungus weevil (family Anthribidae) described by Schaeffer in 1906. The specific epithet "quercus" suggests an association with oak (Quercus), a pattern common in this genus. Anthribidae weevils are typically associated with fungi, often found on decaying wood or fungal fruiting bodies.
