❧ Caterpillar hosts ~7 caterpillar species

Heterotheca supports ~7 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 Heterotheca in North America, including:

Charidryas gabbii · brush-footed butterfly Chlosyne lacinia · Bordered Patch Dichomeris baxa · twirler moth Epiblema scudderiana · Goldenrod Gall Moth Eucosma ridingsana · leafroller moth Heliocheilus paradoxus · Paradoxical Grass 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. Heterotheca is a recorded specialist-bee host, so losing it can mean losing the bee that relies on it.
