Read the passage below then answer the following question.
Milkweed is a plant commonly found throughout fields and pastures and along roadsides in eastern and central North America. It gets its name from the milky white sap that oozes when the plant is broken or cut. Milkweed plants bloom in June and July. When fertilized, the flowers form large seedpods that open in the fall. The following observations were taken from a scientist’s field study of milkweed plants from spring through fall.
In the summer, the sugary nectar secreted by the milkweed’s flowers attracts many bees, butterflies, moths, and a variety of smaller insects that carry away pollen when they depart. Milkweed nectar seems to be the major source of nutrition for several species of small moths, flies, mosquitoes, and ants. Monarch butterflies, which visit in large numbers, lay their eggs on milkweed plants, and the hatching caterpillars feed on the leaves. As fall approaches, milkweed bugs begin to attack the developing seeds, and milkweed beetles eat the foliage.
Aphids, which suck milkweed sap, are found throughout the year. Crab spiders do not feed on the plant itself, but rather on most of the insects that visit the plant. In the two to three weeks while the milkweed plants are in bloom, successful adult female crab spiders may increase ten times in mass before laying their eggs on the inner surf
