Drepanaphis keshenae
Granovsky, 1931
Drepanaphis keshenae is a of in the Aphididae, Drepanosiphinae. First described by Granovsky in 1931, this species belongs to a of aphids that are typically associated with maple trees (Acer spp.). The genus Drepanaphis is characterized by distinctive morphological features and traits tied to their plant relationships. Like other members of its subfamily, D. keshenae is presumed to have complex involving both sexual and phases, with host alternation potentially occurring between maple species.

Identification
Members of the Drepanaphis can be distinguished from other genera by their characteristic body shape and the structure of their siphunculi (cornicles). Within the genus, -level identification requires examination of specific morphological features such as the shape and size of the cauda, the number and arrangement of setae on various body parts, and the structure of the . Drepanaphis keshenae specifically would be distinguished from through subtle differences in these characters, though detailed diagnostic features for this species are not readily available in general literature.
Habitat
As a member of the Drepanaphis, this is associated with maple trees (Acer spp.), which serve as its primary plants. The therefore consists of areas where maple species occur, including deciduous forests, woodlands, urban and suburban landscapes with maple plantings, and riparian zones where maples are common.
Distribution
The precise geographic distribution of Drepanaphis keshenae is not well documented in readily accessible sources. The Drepanaphis has representatives in North America and other regions where maple plants occur. Based on the authorship (Granovsky, 1931) and taxonomic history, this may have been described from material collected in a specific region, though the type locality is not specified in the provided sources.
Diet
As an , Drepanaphis keshenae feeds on phloem sap from its maple trees (Acer spp.). The typical of aphids are used to extract plant fluids, with the insects processing the sugar-rich sap and excreting honeydew as a waste product.
Host Associations
- Acer - primary Drepanaphis is associated with maple trees; specific for D. keshenae not confirmed
Life Cycle
Like other Drepanosiphinae aphids, Drepanaphis keshenae likely exhibits a complex with both parthenogenetic () and sexual reproductive phases. Many drepanosiphine aphids undergo alternation, though some remain on maples throughout their life cycle. The life cycle typically involves as on the host plant, with multiple of parthenogenetic females producing live young during the growing season, followed by the production of sexual morphs (males and females) in autumn that mate and produce the overwintering eggs.
Ecological Role
As a phloem-feeding insect on maple trees, Drepanaphis keshenae contributes to nutrient cycling through honeydew production, which serves as a food source for ants, , and other insects. The aphids may also serve as prey for various including lady beetles, lacewings, and wasps. Their feeding activity, if are dense enough, could potentially influence plant physiology, though specific impacts have not been documented for this .

More Details
Taxonomic history
The was described by Granovsky in 1931. The name Drepanaphis derives from Greek roots suggesting a sickle or curved shape, likely referring to some morphological feature of these aphids. The specific epithet 'keshenae' may honor an individual or reference a locality, though the etymology is not documented in the provided sources.
Research status
This appears to be poorly represented in ecological and biological studies, with only 12 observations recorded on iNaturalist as of the source date. The limited observational record suggests it may be genuinely rare, under-recorded due to identification challenges, or restricted in distribution.
