The monarch butterfly is sometimes called the "milkweed butterfly" because its larvae eat the plant.
In fact, milkweed is the only thing the larvae can eat! If you'd like to attract monarchs to your garden, you can try
planting milkweed (if you live in the right area). You can purchase milkweed seed online from the Butterfly Farm (close window when done purchasing to return to this screen)
Adult female monarchs lay their eggs on the underside of milkweed leaves. These eggs hatch, depending
on temperature, in three to twelve days.
