Stenosphenus
Stenosphenus is a genus of longhorn beetles (family Cerambycidae) first described by Haldeman in 1847. The genus contains approximately 22 described species distributed across North America from the eastern United States through Mexico and into Central America. Some species exhibit specialized host associations with particular tree genera, particularly hickories (Carya). At least one species, Stenosphenus notatus, is notable for overwintering as an adult—an uncommon life history strategy among eastern North American cerambycids.
Stigmella juglandifoliella
Pecan serpentine leafminer
Stigmella juglandifoliella is a microlepidopteran moth in the family Nepticulidae, commonly known as the pecan serpentine leafminer. The species is a specialist herbivore whose larvae create serpentine mines in the leaves of pecan (Carya illinoinensis). It is currently known from a restricted range in the eastern United States.
Stigmella undescribed-species-on-carya
An undescribed species of pygmy moth in the family Nepticulidae, genus Stigmella, associated with Carya (hickory) as a host plant. The species has not yet received a formal scientific name but is recognized as distinct based on host association and presumably morphological or genetic differentiation from described congeners.
Xyleborus celsus
Hickory Timber Beetle
Xyleborus celsus, commonly known as the hickory timber beetle, is a bivoltine ambrosia beetle native to North America. It specializes in colonizing stressed or dying black hickory trees (Carya texana) and other hickory species. The species overwinters as adults and completes development from egg to adult in approximately 35 days. Unlike some invasive congenerics, it appears to be a native primary colonizer of weakened trees rather than an aggressive killer of healthy hosts.
