❧ Caterpillar hosts ~7 caterpillar species

Tephrosia supports ~7 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 Tephrosia in North America, including:

Chioides catillus · skipper butterfly Dichomeris acuminatus · twirler moth Etiella zinckenella · snout moth Semiothisa eremiata · geometer (inchworm) moth Strymon melinus · Gray Hairstreak Thorybes bathyllus · Southern Cloudywing

How we know this (1) Methods & honest limits
Photosynthesis Direct fact

A recorded categorical fact: each species is tagged C3 (standard), C4 (heat/water-efficient) or CAM (succulent, night-time CO₂ uptake) — or a facultative combination. We only show a trait card for the noteworthy C4/CAM cases; C3 is the unremarkable majority, kept in the data but not surfaced as a card.
