❧ Caterpillar hosts ~3 caterpillar species

Bothriochloa supports ~3 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 for introduced plants — native genera typically support far more.

Recorded feeding on Bothriochloa in North America, including:

Heliocheilus paradoxus · Paradoxical Grass Moth Hesperia comma · Silver-Spotted Skipper Meropleon cosmion · owlet moth
