The viceroy (Limenitis archippus) is a North American butterfly. It was long thought to be a Batesian mimic of the monarch butterfly , but since the viceroy is also distasteful to predators, it is now considered a Müllerian mimic instead.
Viceroy butterflies and monarchs (types of admiral butterfly) are both poisonous Müllerian mimics, though they were long thought to be Batesian. Mitochondrial DNA analysis of admiral butterflies shows that the viceroy is the basal lineage of two western sister species in North America. The variation in wing patterns appears to have preceded ...
A last-ditch defence is for the animal's flesh itself to be toxic, as in the puffer fish, danaid butterflies and burnet moths. Many insects acquire toxins from their food plants; Danaus caterpillars accumulate toxic cardenolides from milkweeds (Asclepiadaceae). [56] Some prey animals are able to eject noxious materials to deter predators actively.
The delicate charm of a butterfly, with its fabulous fluttering wings and jewel-toned hues, is a sight to behold.Even so, you may have, at some point in your life, wondered if these colorful ...
Equivalent to Batesian mimicry within a single species, it occurs when there is a palatability spectrum within a population of harmful prey. For example, monarch (Danaus plexippus) caterpillars feed on milkweed species of varying toxicity. Some feed on more toxic plants and store these toxins within themselves.
Aggressive mimicry compared to a defensive form, Batesian mimicry.The mechanism is often called "Wolf in sheep's clothing".The model for an aggressive mimic can be a harmless species, in which case the 3 roles are separate, or the model can be the prey itself, in which case there are only 2 species involved.
Although the term "bird of prey" could theoretically be taken to include all birds that actively hunt and eat other animals, [4] ornithologists typically use the narrower definition followed in this page, [5] excluding many piscivorous predators such as storks, cranes, herons, gulls, skuas, penguins, and kingfishers, as well as many primarily ...
3) The article displays a photograph for the life stages of this butterfly, but does not provide enough text to fully elaborate on the Viceroy’s life cycle. By including this information, the article could explain how the butterfly’s behavior evolves over its lifetime as well as how it competes for resources differently upon developing over ...
