Anelaphus submoestus
Linsley, 1942
Anelaphus submoestus is a of longhorned beetle in the Cerambycidae, described by Linsley in 1942. The Anelaphus includes several twig pruner species whose larvae develop in living branches of deciduous trees, particularly oaks. are typically active in spring and early summer. The species is known from North America, including Mexico and the United States.

Identification
Anelaphus submoestus can be distinguished from other Anelaphus by subtle morphological differences in antennal structure and body proportions. Like other twig pruners in the , have elongated bodies with moderately long . Definitive identification requires examination of genitalia or detailed comparison with . The genus is characterized by larvae that prune twigs by cutting internally near the base before , leaving a distinctive concave cut surface.
Habitat
Deciduous woodlands, particularly areas with oak . Larvae develop within living branches of trees.
Distribution
Recorded from Middle America and North America, specifically Mexico and the United States.
Seasonality
have been observed in spring; larval activity occurs within branches during growing season.
Diet
Larvae feed internally on living wood of deciduous tree branches, particularly oaks (Quercus spp.).
Host Associations
- Quercus - larval living branches
Life Cycle
are deposited on living branches. Larvae bore into and feed within the branch, eventually cutting the branch internally near the base before pupating. The pruned branch falls to the ground, and emerge from the fallen twig.
Behavior
Larvae are twig pruners that sever branches internally, causing them to drop while still attached by a thin outer bark connection. This distinguishes them from simple wood-borers.
Ecological Role
As a twig pruner, this contributes to nutrient cycling by accelerating branch fall and creating entry points for decomposers. Larval galleries may also provide for other organisms.
Human Relevance
Branches pruned by larvae may be collected for rearing and identification purposes. The is of minor economic significance.
