Polygonia interrogationis

Distribution

This butterfly is found mainly in North America, ranging from southern Canada to central Mexico. It is especially prevalent in the eastern United States.

Appearance

The upper side of the wings is bright orange with black spots, resembling the coloration of many other nymphalid butterflies. The underside is more cryptic, with a combination of browns and tans, resembling a dead leaf. The most distinctive feature is a small white mark on the underside of the hindwing, which looks like a question mark, thus the butterfly’s name.

Size

The wingspan of the Question Mark butterfly ranges between 4.5 to 7.5 cm. Caterpillars can reach lengths of about 5 cm.

Habitat

They can be found in a variety of habitats, including wooded areas, parks, gardens, and edges of forests.

Diet

Caterpillar: Primarily feeds on nettles, but they also consume elm, hackberry, and false nettle. Butterfly: Adult butterflies prefer rotting fruit, tree sap, dung, and carrion. However, they will also nectar on flowers, especially when other food sources are not available. They are particularly drawn to flowers like milkweed, asters, and sweet pepperbush.

Lifecycle

Adhering to the general butterfly progression, its lifecycle comprises: egg → caterpillar (larva) → chrysalis (pupa) → adult butterfly.

Defense Mechanisms

Caterpillar: Their coloration allows them to blend into their surroundings, providing camouflage from potential predators. Butterfly: The cryptic underwing coloration allows the butterfly to blend in when it’s resting, making it resemble a dried leaf. This camouflaging technique is crucial for its survival, especially during hibernation. The bright upperwing coloration can also serve as a warning or distraction to potential predators.

Ecological Importance

Beyond their role as pollinators when they nectar on flowers, they are a part of the food chain, serving as prey for various birds and other predators. Their larvae also play a role in controlling the growth of their host plants.

Conservation Status

The Question Mark butterfly is not considered endangered or threatened. It is relatively common within its range.
