❧ Caterpillar hosts ~20 caterpillar species

Hibiscus supports ~20 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 moderate genus.

✦ 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. Hibiscus is a recorded specialist-bee host, so losing it can mean losing the bee that relies on it.
