Red Admiral Vanessa atalanta butterflies are found in ALL 50 US states. They are also found in England, Europe, Canada, and other areas of the world.
The name originally wasn’t ‘Admiral’ but ‘admirable’.
Their host plants include nettles (Uritca species), pellitory (Parietoria sp), and false nettle (Boehmeria cylindrica).
Red Admiral adult butterflies enjoy fruit and flower nectar. Fruit can be added to a garden to help attract Red Admirals as well as other fruit loving butterflies.
They are more readily found in moist environments, where nettle and pellitory grow wild.
Caterpillars fold leaves and stay inside the folded leaf when they are not eating. As they grow, they make nests by sewing two or more leaves together.
Male Red Admiral butterflies are territorial. They will choose a spot as their own territory. A male will sit or perch on a leaf or other item that gives it a clear view of his territory. Anything that enters his territory is often investigated. If it is a female Red Admiral, he will court her. If it is anything else, he will try to chase it away from his area.
