Life Cycle and Development

Egg Stage

1. Shape: Black Swallowtail butterfly eggs are typically round. This is true for many butterflies.
2. Color: Black Swallowtail eggs are usually yellowish-white.
3. Duration: The egg stage for the Black Swallowtail lasts about 4-9 days.

Caterpillar Stage

1. Features: Black Swallowtail caterpillars start off mostly black with a white saddle in the middle, and as they grow, they become green with black bands and yellow spots. They do not have hairs but do have spines.
2. Osmeterium: When threatened, Black Swallowtail caterpillars can extend a Y-shaped, orange or red organ called the osmeterium that releases a foul-smelling secretion.
3. Diet: The caterpillars primarily eat the leaves of plants in the carrot family, including dill, parsley, and fennel.

Pupa Stage

1. Form: The pupa, or chrysalis, is where the caterpillar undergoes metamorphosis.
2. Color: The chrysalis of the Black Swallowtail can be green or brown, depending on its surroundings and where it pupates.
3. Duration: The pupal stage for the Black Swallowtail can last from 10 days to 2 weeks under summer conditions, but if they go into diapause (a form of hibernation), it can last through the winter.

Adult Stage

1. Wings: Adult Black Swallowtails have black wings with yellow and blue markings. Females may also have an iridescent blue band on their hindwings, while males may have more yellow.
2. Feeding: Adult butterflies, including the Black Swallowtail, feed on nectar from flowers using their proboscis.
3. Reproduction: The primary purpose of the adult stage is reproduction.

Once the transformation is complete, the adult butterfly emerges from the pupa and begins searching for a mate.

After mating, the cycle begins anew with the female laying eggs on a suitable host plant.

Habitat and Distribution

Host Plants and Feeding

Caterpillar Host Plants

Caterpillars of black butterflies with blue and yellow spots thrive on specific host plants. These plants are typically found among the carrot family. A few examples include:

• Parsley
• Dill
• Fennel

Predators and Defense Mechanisms

Camouflage and Warning Marks

Black swallowtail butterflies have developed various strategies to protect themselves from predators. One such strategy is camouflage.

These butterflies possess marks and stripes that help them blend in with their environment. Their predominantly dark bodies make it difficult for predators to spot them on tree bark or soil.

Additionally, their vibrant blue and yellow spots may serve as warning marks to ward off potential threats, indicating that they might be poisonous or unpalatable to predators.

Unique Defensive Features

Along with camouflage and warning marks, black butterflies with blue and yellow spots exhibit other unique defensive features:

• Tan and brown colors: These colors help the butterfly blend in with their surroundings, especially when resting on dead leaves or branches.
• Gland secretion: Some butterflies have a specialized gland that produces a foul-smelling or distasteful substance, deterring predators from consuming them.
• Mimicry of veins: These butterflies may have wing patterns that resemble the veins of leaves, further enhancing their camouflage.
