Brachys fasciferus
Brachys fasciferus is a species of metallic wood-boring beetle in the family Buprestidae, tribe Trachyini. It is native to North America. Members of the genus Brachys are leaf-miners as larvae, developing within the leaves of hardwood trees rather than boring through wood, a habit that distinguishes them from most other buprestids.
Dicerca tuberculata
Dicerca tuberculata is a metallic wood-boring beetle in the family Buprestidae. The species occurs in eastern North America, with records from New Brunswick and Nova Scotia in Canada. Like other members of the genus Dicerca, it is a woodboring species whose larvae develop in dead or dying hardwood trees.
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.
Hylecoetus lugubris
Sapwood Timberworm Beetle
Hylecoetus lugubris is a ship-timber beetle (family Lymexylidae) native to North America. The species is currently classified as a synonym of Elateroides lugubris in some taxonomic databases, though iNaturalist maintains it under the genus Hylecoetus. Like other lymexylids, it is associated with dead or decaying wood, where larvae bore into hardwoods. The family is characterized by reduced elytra in some genera, though Hylecoetus species retain more typical beetle morphology compared to the highly modified Atractocerus. The common name 'Sapwood Timberworm Beetle' refers to its larval habit of tunneling in the sapwood of trees.
Mesosini
Mesosini is a tribe of longhorn beetles (Cerambycidae) within the subfamily Lamiinae. The tribe contains approximately 60 described genera distributed primarily across East Asia, Southeast Asia, and parts of the Oriental region. Members are characterized by morphological traits typical of Lamiinae, with some genera exhibiting distinctive features such as elytral tubercles or modified antennae. The tribe includes economically significant species associated with hardwood trees.
Nicagus obscurus
Nicagus obscurus is a small stag beetle in the family Lucanidae. Adults are found under bark of dead hardwoods, particularly oak. Larvae develop in rotten wood of hardwood logs and stumps, and have been specifically recorded from grooves of aspen driftwood. Adults emerge in August. The species occurs across eastern North America from Canada to the southeastern United States.
Perothops
beech-tree beetles, perothopid beetles
Perothops is a genus of false click beetles (family Eucnemidae) and the sole genus in the monotypic subfamily Perothopinae. The genus contains three species: P. witticki, P. cervinus, and P. muscidus. Adults are small (10–18 mm), dark-colored beetles found in forests across the United States. The genus was historically treated as a separate family before being reclassified into Eucnemidae in 1993.
Xylobiops
horned powder-post beetles, red-shouldered bostrichid (X. basilaris)
Xylobiops is a genus of beetles in the family Bostrichidae, commonly known as horned powder-post beetles. The genus was established by Casey in 1898 and contains approximately six described species distributed primarily in North America. These beetles are wood-boring insects associated with dead or dying hardwoods. The most frequently encountered species is Xylobiops basilaris, commonly called the red-shouldered bostrichid.
