❧ Caterpillar hosts ~42 caterpillar species

Juniperus supports ~42 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 strong genus.

Recorded feeding on Juniperus in North America, including:
