Polyphemus moth (Antheraea polyphemus)
Hawkmoths (Sphingidae (family-level entry))
The Lady Bird Johnson Wildflower Center documents chokecherry as a larval host for sphinx moths including the Small-eyed Sphinx, and an adult-food (nectar) source for the Sequoia Sphinx.
European honeybee (Apis mellifera)
Missouri Botanical Garden PlantFinder lists the fragrant white flower racemes as attracting butterflies and the plant as bee-visited; honey bees forage the open, accessible spring bloom though the sources do not name the species.
Mining bees (Andrena spp.)
Eastern bluebird (Sialia sialis)
Baltimore oriole (Icterus galbula)
American robin (Turdus migratorius)
Eastern songbirds (multi-species) (multiple species (Passeriformes))
The Lady Bird Johnson Wildflower Center records the blue-black cherries as important wildlife food in July and August for numerous bird species; Missouri Botanical Garden PlantFinder lists the plant as attracting birds.
Cedar waxwing (Bombycilla cedrorum)
Cedar waxwings are fruit specialists that feed heavily on native cherries; the sources document chokecherry fruit as broadly important bird food, so waxwing use is expected though not named species-by-species.
White-tailed deer (Odocoileus virginianus)
Black-capped chickadee (Poecile atricapillus)
Downy woodpecker (Dryobates pubescens)
Lady beetles (Coccinellidae)
