Colour pattern[change | change source]
The wings are orange. They have black veins and black wing edges. There is a black band across the hind wing (bottom wing). This band can sometimes be faint or missing if the butterfly lives in the southwestern United States. In Florida, the Viceroy is dark reddish brown instead of orange. The wingspan ranges from 6.6 to 7.6 cm (2.6 to 3 in).
Its significance[change | change source]
The caterpillar feeds on trees in the willow family Salicaceae, including willows (Salix), and poplars and cottonwoods (Populus). The caterpillars store the salicylic acid in their bodies, which makes them bitter, and upsets predators' stomachs. As further protection, the caterpillars, as well as their chrysalis stage, resemble bird droppings.
The Viceroy (Limenitis archippus) is a North American butterfly with a range from the Northwest Territories along the eastern edges of the Cascade Range and Sierra Nevada mountains, southwards into central Mexico.
Its wings have an orange and black pattern, and over most of its range it is a Müllerian mimic with the Monarch butterfly (Danaus plexippus). What this means is that they are both bitter tasting, and they both use the same pattern of colours where they live in the same territory. Müllerian mimicry is a shared warning advertisement, in this case of foul taste.
Flight period[change | change source]
Adults fly in the late morning and early afternoon.
The Viceroy can be found from June to July in northern Canada. It can be found from May to October in southern Canada and the northern United States. It is found all year in southern Florida. In the southwestern United States, it is seen from April to November.
Habitat[change | change source]
This butterfly is found in a wide range of wet, open places such as water edges, wet meadows, and freshwater marshes.
Life cycle[change | change source]
The female lays her eggs singly. They are laid at the tip of the host plant leaf (the host plant is the plant that the caterpillar feeds on). The egg is pale green or pale yellow. It turns gray later. The caterpillar feeds at night. It mimics a bird dropping. It is white, brown, black, and olive green. There are two greenish bumps on the thorax. There are also two spines near the head. The chrysalis also mimics a bird dropping. It is white, brown, and black. There is a large brownish bump on the abdomen. The caterpillar hibernates in a leaf shelter. It lays one set of eggs in northern Canada, and 2-3 more groups in southern Canada and the United States.
