More about this plant

Allium tricoccum is a bulbous perennial flowering plant in the amaryllis family Amaryllidaceae. It is a North American species of wild onion or garlic found in eastern North America. Many of the common English names for this plant are also used for other Allium species, particularly the similar Allium ursinum, which is native to Eurasia. An edible plant, Allium tricoccum is used in a variety of North American and indigenous cuisines, and has also been used by Native Americans in traditional medicine. A French rendering (chicagou) of a Miami–Illinois name for this plant is the namesake of the American city of Chicago. Wikipedia →

❧ Caterpillar hosts ~21 caterpillar species

Allium supports ~21 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 Allium in North America, including:

How we know this (1) Methods & honest limits
Flower colour Derived

McKenzie et al. assigned each species a flower colour with a GPT-4V vision model over iNaturalist photos. We use the confident tier plus a separately-labelled lower-confidence top-up (mostly inconspicuous green/brown flowers), and render it as a small tint — never as an asserted fact, and kept out of the written synopsis.

Honest limits: AI image inference (~87% expert agreement on the confident tier); a decorative, confidence-tiered indicator, not a measured trait.
