A monarch butterfly on swamp milkweed Asclepias syriaca seed pods, upper image from August and lower from December Milkweed sprout, a few days after sowing Chemical structure of oleandrin, one of the cardiac glycosides. Members of the genus produce some of the most complex flowers in the plant kingdom, comparable to orchids in complexity.
Common names include sand vine, honeyvine, honeyvine milkweed, bluevine milkweed, climbing milkweed, and smooth swallow-wort. [2] The root system of C. laeve can cause it to be very difficult to eradicate, especially in agricultural fields. [3] It is a larval food of monarch butterflies [4] and milkweed tussock moth larvae.

A. tuberosa is a larval food plant of the queen and monarch butterflies, as well as the dogbane tiger moth, milkweed tussock moth, and the unexpected cycnia. [3] [12] Because of its rough leaves and trichomes, it is not a preferred host plant of the monarch butterfly but caterpillars can be reared on it successfully.
Both the milkweed tussock and the monarch caterpillars eat the cardiac glycoside-laden milky sap of milkweed and have evolved mechanisms to retain those toxins in their bodies after metamorphosing ...
Growing milkweed from seed is one of the easiest ways to help declining monarch butterflies. In December 2024, the U.S. Fish and Wildlife Service proposed monarch butterflies, whose numbers in the ...
Will monarchs lay eggs on milkweed with aphids? Monarchs are usually undeterred by the presence of milkweed aphids and continue to lay eggs on milkweed plants even if aphids are around. What eats ...
O. fasciatus is a specialist herbivore that frequently consumes milkweed seeds. [19] In addition to its plant-based diet, O. fasciatus has been observed feeding on aphids, monarch caterpillar eggs, and larvae, displaying opportunistic behavior. [4] [20] This bug also feeds on A. nivea, Sarcostemma clausa, Calotropis procera, and Nerium oleander.
While tropical milkweed may effectively sustain monarch larvae, the perennial growth of the plant takes ill effect on the monarchs' migratory patterns and may have other physiological effects. [8] Use of the tropical milkweed in gardens has disrupted monarch migrations notably in California, Texas, Florida, and South Carolina. [ 9 ]
