❧ Caterpillar hosts ~5 caterpillar species

Passiflora supports ~5 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 Passiflora in North America, including:

Agraulis vanillae · Gulf Fritillary Agrotis subterranea · owlet moth Dryas iulia · Julia Heliconian Euptoieta claudia · Variegated Fritillary Heliconius charitonius · brush-footed butterfly Heliconius erato · Crimson Patched Longwing

Paratrea plebeja · Plebeian Sphinx Sabulodes caberata · geometer (inchworm) moth
Keystone count (genus-level) from Warren II 2026 (CC0) · Tallamy host-use records. Named species (a documented Nearctic sample, not exhaustive) from NHM HOSTS (CC0).
✦ 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. Passiflora is a recorded specialist-bee host, so losing it can mean losing the bee that relies on it.
