Adult butterflies, as well as caterpillars, have something called host plants. A host plant is where eggs are laid.

After hatching from their eggs, the larvae derive their nutrition and food from such plants. These butterflies from the family Papilionidae, use Umbelliferae plants as their hosts. Such plants include plants called the Queen Anne's lace, carrots, parsley, parsnip, caraway, and more.

Once the caterpillars grow into adults, they grow wings that are mostly black with spots of yellow. Apart from yellow dots, you can also spot blue, orange, and red on their wings.

Adult members of these beautifully colored butterflies, whose wings are a combination of black, yellow, orange, blue, and red, can be seen flying above a range of open areas. To know more about their behavior, dive right into the facts below.

The wings of the adult butterflies are black in color. There are a couple of rows of yellow spots running down the middle of each wing.

Females have lesser, or negligible, yellow spots. The hindwing of the male is adorned with blue dots on the upper surface, whereas it is a blue area or band in the case of females. A big red dot that has another black circle within it decorates the upper part of the hindwings.

Underneath this wing, there are multiple reddish-orange spots. Their appearance is quite different from other species, like the purple emperor butterfly.

What do they eat?

This species is herbivorous in nature. Even though they have a transformative life cycle, their diet remains somewhat uniform throughout the Black Swallowtail life cycle.

The Black Swallowtail butterflies primarily feed on the Umbelliferae plant, which is also their host plant. Such host plant includes dill, celery, Queen Anne's lace, parsley, caraway and other plants of the carrot family.

Although these plants are rich in a chemical called psoralen, the Black Swallowtail butterfly and caterpillar feeds on them since their bodies can flush out the toxins.

As larvae, they feed on the flowers of these plants of the carrot family. Adults, on the other hand, are prone to have mud and nectar as their food.
