❧ Caterpillar hosts ~6 caterpillar species

Coreopsis supports ~6 caterpillar species.

Native butterfly & moth caterpillars are the base of the terrestrial food web — most songbirds rear their young almost entirely on them. As a host for native Lepidoptera this is a modest genus.

Recorded feeding on Coreopsis in North America, including:

Agonopterix atrodorsella · concealer moth Argyrotaenia franciscana · Orange Tortrix Argyrotaenia isolatissima · leafroller moth Coleophora acamtopappi · casebearer moth Euproserpinus phaeton · Phaeton Primrose Sphinx Homoeosoma electella · Sunflower Moth

✦ Bees specialist-bee host

Specialist native bees depend on it.

Some native bees are pollen specialists (oligolectic) — they raise young only on pollen from particular plant genera. Coreopsis is a recorded specialist-bee host, so losing it can mean losing the bee that relies on it.
