What does this plant do for wildlife?
Caterpillars eat the leaves of host plants; adults drink nectar from many flowers. Caterpillars also feed nesting birds.
Source: NC Native Plant Society: butterfly gardening.
- A flower full of butterflies may not feed a single caterpillar.
- Records are for the plant's genus, not the species, and missing records do not prove absence.
- Records show what a plant can support. They don't promise the animals will find your yard.
Four ways a plant helps
- Caterpillar host
- Caterpillars eat its leaves. Counted as caterpillar species recorded on the genus, for species whose range includes West Virginia. Shropshire & Tallamy 2025, ZooKeys 1261
- Nectar and pollen
- Bees and adult butterflies feed at its flowers. Counted as bee species recorded on the genus in Southeastern records. Flower visits do not confirm feeding or pollination. Noori, Seltmann & Orr 2026, GloBI bee-plant interactions
- Fruit and seeds
- Direct food only: birds recorded eating this genus across North America. Not a record of what birds eat in West Virginia. Avian Diet Database
- Shelter
- Cover and nest sites. Quercus has no shelter records yet.
Caterpillars on host plants also feed nesting birds, so a host plant feeds birds even without fruit.
