❧ Caterpillar hosts ~17 caterpillar species

Arctostaphylos supports ~17 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 Arctostaphylos in North America, including:

Acronicta perdita · owlet moth Aethaloida packardaria · geometer (inchworm) moth Amorbia cuneanum · leafroller moth Amphipyra pyramidoides · Copper Underwing Anacamptodes clivinaria · Mountain Mahogany Looper Anarta cordigera · owlet moth

Ancylis comptana · leafroller moth Antaeotricha manzanitae · concealer moth Apharetra californiae · owlet moth Argyrotaenia franciscana · Orange Tortrix Aseptis ethnica · owlet moth Aseptis fumeola · owlet moth Aseptis perfumosa · owlet moth Automeris cecrops · Cecrops Eyed Silkmoth
Keystone count (genus-level) from Warren II 2026 (CC0) · Tallamy host-use records. Named species (a documented Nearctic sample, not exhaustive) from NHM HOSTS (CC0).
✦ Bees specialist-bee host · 3 bee visitors

Specialist native bees depend on it.

Some native bees are pollen specialists (oligolectic) — they raise young only on pollen from particular plant genera. Arctostaphylos 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.
