Hairystem Gooseberry Ribes hirtellum

Native Specialist-bee host

Hairystem Gooseberry is a perennial shrub native to Canada, the lower 48 states, and Saint-Pierre & Miquelon. It grows to 4 ft and blooms May – Jun. A host for pollen-specialist native bees.

❧ Caterpillar hosts ~99 caterpillar species

Ribes supports ~99 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.

Recorded feeding on Ribes in North America, including:

Abagrotis nefascia · owlet moth Acerra normalis · owlet moth Acleris maccana · leafroller moth Acronicta impressa · Impressed Dagger Moth Actebia fennica · owlet moth Aglais milberti · Milbert's Tortoiseshell

✦ Bees specialist-bee host · 1 bee visitor

Specialist native bees depend on it.

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

How we know this (2) 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.

Kattge, J. et al. TRY plant trait database — Categorical Traits Dataset (2012).
Climate niche (heat tolerance & native rainfall) Derived

We take the plant’s U.S. county range and look up each county’s long-term climate, then summarise: native rainfall = the median annual rainfall across its counties; heat tolerance = the warm end (90th percentile) of average temperature across its range (mirroring how our cold-hardiness floor uses an extreme). Counties + medians blunt the roadside/observer bias that makes point-level climate unreliable. Needs at least five placeable counties.

Honest limits: A realized, sampling-biased niche (where it has been recorded, not its physiological optimum), and county climate is coarse — large Western counties span deserts and mountains. Derived guide, never a measured fact.

Realized-niche / climate-envelope approach (Pearson & Dawson 2003; Soberón 2007). Climate: NOAA NCEI nClimDiv county normals (1991–2020).
Derived values are computed from open data by a published method — labelled, cited, and never shown as a direct observation. Full methodology →
