Butterfly: Wingspan: 2 1/2-3 inches (6.4-7.6 cm). Above, wings are orange with black veins. Outer margins are black with white spots. Both forewing and hindwing have a thin black band. Below, wings are similar but not as dark.
ID Tip: Strongly resembles the Monarch but has a thin black line across the hind wings that Monarchs lack.
Egg: Gray-green. Typically laid singly on the tip of host plant leaf.
Caterpillar: Resembles bird droppings in all stages. May be mottled brown or green; has creamy blotches and two knobby horns on thorax. Partially grown caterpillars from the third brood spend the winter in a specially rolled leaf called a hibernaculum that they silk to a branch. Feeding and development resumes that following spring. Note: To distinguish Viceroy caterpillars from Red-Spotted Purple caterpillars, look for clubbed rather than unclubbed projections behind the head.
Chrysalis: Shiny brown and white. Abdomen is paler. Thorax has a a large, knob-like projection.Also resembles a bird dropping.
Viceroys are consummate mimics. Although they strongly resemble Monarchs, they are actually closely related to Red-Spotted Purples, also incredible mimics. The two species are drastically different in coloration, but their shapes are almost identical. The family ties are also evident in early developmental stages, where egg, caterpillar, and chrysalis are almost indistinguishable.
Much of the classic and well-known literature about Monarch/Viceroy mimicry suggested that palatable Viceroys mimic unpalatable Monarchs in order to gain some protection from predators. However, both butterfly species are at least somewhat distasteful, so each benefits from looking like the other. Viceroy caterpillars taste bad because their bodies hold on to the salicylic acid contained in their willow hosts, which makes them bitter.
Viceroys fly with a distinctive flap and glide pattern that helps to distinguish them from Monarchs. They are found throughout Alabama, wherever willows grow.
A dot on the county map indicates that there is at least one documented record of the species within that county. In some cases, a species may be common throughout the county, in others it may be found in only a specific habitat.
The sightings bar graphs depict the timing of flight(s) within each of three geographic regions. Place your cursor on a bar within the graph to see the number of individuals recorded during that period.
The abundance calendar displays the total number of individuals recorded within each week of the month. Both the graphs and the calendar are on based data collection that began in 2000.
The records analyzed here are only a beginning. As more data is collected, these maps and graphs will paint a more accurate picture of distribution and abundance in Alabama. Submit your sightings to email@example.com.

If your landscape includes a pond, lake, or stream, allowing willows to grow may encourage Viceroys as well as Mourning Cloaks and Red-Spotted Purples to take up residency.
