Elytroleptus rufipennis
Elytroleptus rufipennis is a longhorn beetle (Cerambycidae) described by LeConte in 1884. It belongs to the tribe Trachyderini, a group known for often striking coloration and patterns. The species name 'rufipennis' refers to reddish wing covers. Records indicate presence in Mexico and the United States.
Enaphalodes
Enaphalodes is a genus of longhorn beetles (Cerambycidae) in the tribe Elaphidiini, established by Haldeman in 1847. The genus contains approximately ten described species distributed across North America, with several species being significant wood-boring pests of oak trees. The most extensively studied species, E. rufulus (red oak borer), has been implicated in major oak mortality events in the Ozark and Ouachita Mountains during outbreak conditions. Species in this genus are characterized by their association with hardwood hosts, particularly oaks (Quercus spp.), and their larvae create extensive galleries in the phloem and wood of host trees.
Enaphalodes atomarius
Robust Oak Borer
Enaphalodes atomarius, commonly known as the robust oak borer, is a species of longhorn beetle in the family Cerambycidae. First described by Dru Drury in 1773 from New York City, this beetle is known to be attracted to ultraviolet and mercury-vapor lights in mesic lowland deciduous forests. It has been documented in bait traps using ethanol and red wine mixtures in xeric dolomite prairie remnants and dry upland deciduous forests.
Enaphalodes cortiphagus
Enaphalodes cortiphagus is a species of longhorned beetle in the family Cerambycidae, described by Craighead in 1923. It belongs to the tribe Elaphidiini and is considered rare in collections. The species has been documented at select locations in eastern North America, including Trail of Tears State Park in Missouri, where it occurs in mesic forest habitats with eastern tree species.
Enaphalodes rufulus
Red Oak Borer
Enaphalodes rufulus, commonly known as the Red Oak Borer, is a native North American cerambycid beetle that develops in oak trees. It is typically associated with stressed or declining oaks and normally occurs at low population densities. However, the species gained significant attention following a major outbreak in the Ozark and Ouachita Mountains during the late 1990s and early 2000s, which contributed to widespread mortality of northern red oak. The beetle has become an important subject of ecological research regarding native insect outbreaks, tree resistance mechanisms, and climate-insect interactions.
