More about this plant

Aquilegia micrantha var. mancosana is a perennial flowering plant which is a variety of the Aquilegia (columbine) species Aquilegia micrantha in the family Ranunculaceae. The variety's first recorded observance was in 1891. It was first described by the American botanist Alice Eastwood as native to a single cavern of the Johnson Canyon in Ute Mountain Tribal Park, Colorado, United States. Described as lacking nectar spurs – something unusual among members of the Aquilegia genus – the plant was observed in the same location the next year. From then until the early 21st century, it had not been observed again in the wild and was presumed extinct. Despite this, it was still listed in Colorado floras. It has since been observed again at its original location. Wikipedia →

❧ Caterpillar hosts ~12 caterpillar species

Aquilegia 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.
