[239] [240] The plant's low levels of cardenolides may also deter monarchs from laying eggs on the plant. [241] While A. tuberosa 's colorful flowers provide nectar for many adult butterflies, the plant may be less suitable for use in butterfly gardens and monarch waystations than are other milkweed species.

They are on wing year round in southern Texas and the tropics. There are several generations per year. [4] Adults feed on flower nectar. The larvae feed on the leaves of various low-growing plants of the family Acanthaceae, [5] including Diciliptera brachiata, Jacobinia carnea, Beloperone, Siphonoglossa, and Ruellia species.
Published lists of host plants for butterflies and other pollinators can help select the plant species desired in the garden.

An estimated 90% of the food we consume is affected by pollination, and more directly, approximately 75% of flowering plants. [41] The loss of butterflies could lead to a decline in agricultural production and quality of crops, as the pollination of crops via butterflies promotes genetic diversity which can help crops adapt to fight off new ...

Monarch butterflies are thought to respond to different cues that promote the fall season southern migration. These include the angle of light coming from the sun, the senescence of larval host milkweed plants, the decreasing day period and temperature drop. [21] The migration begins at the northernmost summer range approximately in August.
