Mate Ilex paraguariensis

Also known as: holly · Paraguay tea · Yerba mate · Yerba Maté

Mate is an introduced perennial tree, found in Hawaii.

More about this plant

Yerba mate or yerba maté, Ilex paraguariensis, is a plant species of the holly genus native to South America. The leaves of the plant can be steeped in hot water to make a beverage known as mate. Brewed cold, it is used to make tereré. Both the plant and the beverage contain caffeine. Wikipedia →

❧ Caterpillar hosts ~39 caterpillar species

Ilex supports ~39 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 Ilex in North America, including:

Acharia stimulea · Saddleback Caterpillar Moth Apatelodes torrefacta · Spotted Apatelodes Argyrotaenia citrana · leafroller moth Argyrotaenia velutinana · Red-Banded Leafroller Autographa californica · Alfalfa Looper Moth Automeris io · giant silk 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. Ilex 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
Leaf build Direct fact

We read each species’ measured specific leaf area (leaf area per unit dry weight) from the Global Spectrum dataset and band it: thin & fast (high SLA), medium, or thick & tough (low SLA). The global median is about 10 mm²/mg.

Honest limits: A species-mean from pooled measurements — individual plants vary with light and site. A broad strategy signal, not a precise per-plant figure.

Díaz, S. et al. (2022) The global spectrum of plant form and function: enhanced species-level trait dataset. Scientific Data 9:755.
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.
