Mallow Bindweed Convolvulus althaeoides

Mallow Bindweed is an introduced perennial vine, found in the lower 48 states. It grows to 1.4 ft.

More about this plant

Convolvulus althaeoides is a species of morning glory known by the common names mallow bindweed and mallow-leaved bindweed. This flowering plant is native to the Mediterranean Basin, but it is occasionally seen in other areas of similar climate, such as California in the United States, where it has been introduced. This is a climbing perennial plant with solitary flowers on long peduncles. The flower is a funnel-shaped pink bloom three or four centimeters wide. The leaves are deeply divided into narrow, fingerlike lobes. Wikipedia →

❧ Caterpillar hosts ~9 caterpillar species

Convolvulus supports ~9 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 modest genus for introduced plants — native genera typically support far more.

Recorded feeding on Convolvulus in North America, including:

Agrius cingulata · Pink-Spotted Hawkmoth Bedellia somnulentella · Convolvulus Leafminer Cnephasia longana · leafroller moth Emmelina monodactyla · plume moth Faronta albilinea · owlet moth Lacinipolia basiplaga · owlet moth

✦ Bees specialist-bee host · 13 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. Convolvulus 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.
