North America is home to multiple black and blue butterflies. These colorful butterflies are seen in all sizes and all types of color combinations.
Some are only black and blue while others also show orange, white, green, tan, and brown colors.
Additional coloring on black and blue butterflies is specific to dots, marks, and stripes.
Many blue butterflies have dark visible veins across the wings.
These species of butterflies live in all parts of the US. Many are found in the Southern parts, especially those also native to Central and South America.
However, black and blue butterflies are also common in Northern states such as Ohio and even live in Alaska. The following species are considered the most common.
1. Red-spotted Admiral
The Red-spotted Admiral (Limenitis arthemis) is a common black and blue butterfly in North America. The species has black wings with blue margins and red spots.
The wingspan of the species can reach a maximum of 2-3 inches.
Butterflies of this genus are common in forests across the Eastern United States.
Birch and other evergreen forests are among their favorite habitats.
This butterfly can be seen in many other environments at higher altitudes.
Red-spotted Admirals are versatile when it comes to feeding. They feed on sap but they also eat carrion and even dung.
Red-spotted Admirals don’t primarily feed on plant nectar. They might only consider plant nectar as an alternative to planting sap.
2. Pipevine Swallowtail
Pipevine Swallowtails (Battus philenor) are mostly black butterflies with vivid blue coloring on the hindwings.
They also have light blue marginal spots.
Color differences are seen between males and females as the female has more iridescent blue coloring.
Pipevine Swallowtails are known to feed on the nectar of a few flower species. They’re a common sight on a thistle.
These butterflies also sink on pink flowers rich in nectar.
Pipevine Swallowtail caterpillars have a lower pupation rate due to their habits of establishing themselves on potentially toxic plants.
Caterpillars of the species are often seen on toxic Aristolochia plants which eventually kill them.
3. Summer Azure
Summer Azures (Celastrina neglecta) have a long flight season in Eastern and Central US. The species remains active until October.
Summer Azures have a light blue color with black margins. The light blue nuance of the wings can appear closer to white in females.
This species feeds on the nectar of various flower while its larvae feed on various types of dogwood.
Summer Azures are some of the common small blue butterflies as they have a wingspan slightly longer than 1 inch.
The caterpillar of the species doesn’t resemble the black and blue adults. It has a light green uniform color.
Atala (Eumaeus atala) is a common black and blue species in Florida’s subtropical climate.
This butterfly has black wings with blue spots and a red abdomen.
Its wingspan measures at least 1.5 inches and can sometimes reach 2 inches.
This species feeds on many subtropical flowers for their nectar. This includes feeding on the nectar of wild coffee.
Atala’s very specific habitat requirements mean this species has very specific needs in terms of food.
Its status is endangered even if it has been reported in small numbers in neighboring states.
5. Mangrove Skipper
Both Atala and Mangrove Skippers (Phocides pigmalion) are present in Southern Florida.
The difference in coloring is that the Mangrove Skipper is darker.
It has a dark violet-blue color with a black body and black veins.
