Paonias astylus is a sphinx moth native to eastern North America, commonly known as the huckleberry sphinx. The exhibits periods in the southern portion of its range and patterns in the north. have reduced mouthparts and do not feed; larvae specialize on woody plants in several including Ericaceae and Salicaceae.

Identification
The combination of pink hindwing patches with dark margins distinguishes Paonias astylus from other eastern North American sphinx moths. Similar P. excaecatus (blinded sphinx) has more extensive pink on hindwings with blue-gray shading toward the base; P. myops (small-eyed sphinx) is larger with more rounded forewings. The gray-brown forewings with relatively indistinct patterning separate P. astylus from more boldly marked sphingids.

Appearance
Wingspan 55–65 mm. Forewings are typically gray-brown with variable darker markings. Hindwings display a distinctive pink or rose-colored patch with dark borders, characteristic of the Paonias. Body is robust with a tapering typical of sphingid .
Habitat
Deciduous and mixed woodlands, forest edges, and shrubby areas where larval plants occur. Associated with blueberry barrens, wetland margins, and riparian corridors supporting Salix and Vaccinium.
Distribution
Eastern North America: Maine south to Florida, west to Missouri and Mississippi. Core range spans the Atlantic coastal plain and interior eastern deciduous forest.
Seasonality
active March–June and again in September in Florida (two ). Single generation with adults in July in northern portions of range. Larvae present during growing season corresponding with adult periods.
Diet
Larvae feed on Vaccinium (blueberry, including V. vacillans and V. corymbosum), Prunus, Andromeda, and Salix. do not feed.

Life Cycle
Complete with , larva, pupa, and stages. stage not explicitly documented in available sources; likely pupal given northern .
Ecological Role
Larval herbivore on woody shrubs; contributes to nutrient cycling through leaf consumption. serve as potential prey for including bats and birds.
Human Relevance
Minor economic significance as a blueberry pest; occasional presence noted in cultivated Vaccinium plantings. occasionally attracted to artificial light sources.
