What does the zebra swallowtail butterfly eat?

Zebra swallowtail butterflies feed on the nectar and pollen of flowers like blueberry, blackberry, lilac, redbud, verbena , and common milkweed . Sometimes they collect pollen from flowers using the proboscis and digest it to absorb proteins. The extra energy and nutrition from these proteins help them to mate and lay eggs for longer periods.

Some butterflies such as the Monarch and Pipevine Swallowtail eat poisonous plants as caterpillars and are poisonous themselves as adult butterflies. Birds learn not to eat them. Other good-tasting butterflies (called “mimics”) come to resemble them and thus benefit from this “umbrella” of protection.
