Identifying Butterfly Species Based on Color: Yellow and Black Butterflies
Swallowtails are a group of butterflies belonging in the family Papilionidae. They are identifiable by their predominantly black and sometimes yellow colored wings and are found almost everywhere in the world except in Antarctica. All in all, there are around 600 species of swallowtails in the world. However, you can only find 30 of them in the United States.
Aside from their coloring, these butterflies are also known for having tails located in their hindwings and for being relatively larger in size. In fact, Swallowtails are the largest kind of butterflies that are found in Great Britain.
Some swallowtails have blue and orange markings mixed in with their usual yellow and black colors with some having more blue pigment than yellow. Anyway, here are some swallowtail butterflies which have prominent yellow and black colors in their wings.

The Zebra Longwing Butterfly
If none of the swallowtail butterflies we mentioned above matched the yellow, black butterfly you’re trying to identify, our last (and best) bet is that it’s a zebra longwing butterfly that you’re looking for.
As its name implies, this butterfly is characterized by its pale yellow and black striped wings. The zebra longwing butterfly (which scientific name is Heliconius charitonia) also has some rows of small yellow spots found on the rear end of its wings.
They are usually found in Florida and some areas in the state of Texas but can also be seen fluttering around in central states during warmer seasons.
Despite being easily startled, zebra longwing butterflies are quite easy to observe because they have a habit of returning to the same spots every day.
Didn’t find what you’re looking for?
Maybe you confused the color of the butterfly you saw? You see, butterfly wings are interesting because they are covered in multiple layers of thousands of really small scales. With light hitting these layers in different ways, some colors may appear as another. Often, what we see is already the combination of the various colors on a butterfly’s wings which may lead to some misidentification.
However, we’d also like to note that predominantly yellow and black-colored butterflies are easier to identify because these two colors are pigment colors instead of structural. This means that the surface colors you see when you spot them out in your garden are the actual colors of their wings regardless of the way the light hits them. Butterflies with blue, purple and white wings can easily appear to have different colored wings.
