Guides
Cononotus bryanti
Cononotus bryanti is a species of longhorned beetle in the family Cerambycidae, subfamily Cerambycinae, tribe Tillomorphini. The genus Cononotus belongs to a group of ant-mimicking cerambycids characterized by small body size and modified elytral structures. Like other members of this tribe, C. bryanti likely exhibits morphological adaptations for myrmecomorphy (ant mimicry), though specific details for this species are not well documented in available literature. The species was described by Van Dyke in 1953 and is part of the Nearctic fauna.
Euderces
Euderces is a genus of small longhorn beetles in the family Cerambycidae, characterized by remarkable ant-mimicry. Most species measure less than 5 mm in length and exhibit Batesian mimicry of ants, particularly species of Camponotus. The genus has its center of diversity in southern Mexico and Guatemala, with species distributed from North America through South America. Notable examples include E. velutinus, which closely resembles the tropical ant Camponotus sericeiventris. Four species occur in the United States.
Euderces bicinctus
Euderces bicinctus is a species of ant-mimicking longhorned beetle in the family Cerambycidae, described by Linsley in 1935. Like other members of the genus Euderces, it exhibits Batesian mimicry of small ants, an adaptation common among the Tillomorphini tribe. The species is distributed in North and Middle America. Specific details regarding its biology and ecology remain poorly documented in published literature.
Euderces picipes
Euderces picipes is a small ant-mimicking longhorned beetle in the family Cerambycidae. The species exhibits pronounced geographic color variation: northern populations are uniformly black, while southern and southwestern populations display red or orange coloration on the abdomen or elytral edges. This color polymorphism was formerly considered to represent separate species, with red forms described as E. abdominalis, but is now recognized as intraspecific variation correlated with geographic distribution. Like other members of the genus, adults are effective Batesian mimics of ants.
Euderces reichei
Euderces reichei is a species of ant-mimicking longhorned beetle in the family Cerambycidae, described by John Lawrence LeConte in 1873. Adults are small, typically under 10 mm in length, and exhibit Batesian mimicry of ants through their compact body form, constricted waist-like appearance, and coloration. The species has been recorded across the eastern and central United States, with adults frequently encountered on flowers of flowering dogwood (Cornus florida) during spring.
Pentanodes
Pentanodes is a genus of longhorn beetles (Cerambycidae) established by Schaeffer in 1904. The genus belongs to the tribe Tillomorphini within the subfamily Cerambycinae. Two species are currently recognized: Pentanodes albofasciatus (Fisher, 1932) and Pentanodes dietzii (Schaeffer, 1904). The genus is poorly documented in scientific literature, with limited information available on its biology and ecology.
Tetranodus
Tetranodus is a genus of longhorn beetles (Cerambycidae) in the tribe Tillomorphini. The genus was established by Linell in 1896 and contains seven described species distributed in the Americas. Species have been described from the late 19th century through the late 20th century, with several described by Chemsak and colleagues. The genus is placed in the subfamily Cerambycinae, a diverse group of primarily wood-boring beetles.
Tilloclytus
Tilloclytus is a genus of longhorned beetles (Cerambycidae) established by Bates in 1885, currently comprising 14 recognized species distributed across North America, the Caribbean, and northern South America. The genus is notable for containing ant-mimicking species, most notably Tilloclytus geminatus, which exhibits Batesian mimicry of small ants through body shape, coloration, and behavior. Adults are typically small (<10 mm), with some species occasionally found on flowers though they appear less frequently associated with floral visitation than related ant-mimicking genera such as Molorchus and Euderces.
