❧ Caterpillar hosts ~40 caterpillar species

Syringa supports ~40 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 for introduced plants — native genera typically support far more.
