Wright's Deervetch Lotus wrightii

Native Specialist-bee host
Deer favourite — Rated highly palatable to browsing deer — so where deer are around, expect this one to get nibbled. It's a documented preference, not a certainty: pressure swings with the place and season, and a fenced or low-deer yard may be untouched.

Wright's Deervetch is a perennial wildflower native to the lower 48 states. It grows to 1 ft and blooms Apr in full sun – part shade, with brown fruit. A host for pollen-specialist native bees.

❧ Caterpillar hosts ~12 caterpillar species

Lotus supports ~12 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 moderate genus.

Recorded feeding on Lotus in North America, including:

Arachnis picta · Painted Tiger Moth Argyrotaenia citrana · leafroller moth Arla diversella · twirler moth Callophrys dumetorum · Lotus Hairstreak Celastrina argiolus · Holly Blue Coleophora accordella · casebearer moth

✦ Bees specialist-bee host

Specialist native bees depend on it.

Some native bees are pollen specialists (oligolectic) — they raise young only on pollen from particular plant genera. Lotus is a recorded specialist-bee host, so losing it can mean losing the bee that relies on it.

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.
