❧ Caterpillar hosts ~2 caterpillar species

Woodwardia supports ~2 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 Woodwardia in North America, including:

Callopistria floridensis · Florida Fern Moth Hemileuca nevadensis-complex · giant silk moth Papaipema stenocelis · Chain Fern Borer 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).
