Its wings feature an orange and black pattern, and over most of its range it is a Müllerian mimic [4] with the monarch butterfly (Danaus plexippus).The viceroy's wingspan is between 53 and 81 mm (2.1 and 3.2 in). [5]
The monarch butterfly or simply monarch (Danaus plexippus) is a milkweed butterfly (subfamily Danainae) ... A Müllerian mimic, the viceroy butterfly, ...
The viceroy butterfly (top) appears very similar to the noxious-tasting monarch butterfly (bottom). Although it was for a long time purported to be an example of Batesian mimicry, the viceroy has recently been discovered to be just as unpalatable as the monarch, making this a case of Müllerian mimicry.
In December 2024, the U.S. Fish and Wildlife Service proposed monarch butterflies, whose numbers in the West have declined by over 90% since the 1980s, be classified as “threatened”—one step ...
However, if mimics become more abundant than models, then the probability of a young predator having a first experience with a mimic increases. Batesian systems are therefore most likely to be stable where the model is more abundant than the mimic. [44] There are many Batesian mimics among butterflies and moths.
Lycorea – mimic queens; Protoploea – magpie butterfly; The fossil milkweed butterfly Archaeolycorea from the Oligocene or Miocene Tremembé Formation of Brazil is often assigned to this tribe, specifically the Euploeina. Whether this is correct is not entirely certain. Examples of butterflies from several genera in tribe Danaini
Ps. poggei Dew. is a wonderfully faithful mimic of Danaida chrysippus.Both wings red-yellow above with fine black veins, but without black streaks between the veins; the apex of the forewing is black as far as the base of vein 4, with a -white subapical band composed of three large spots in cellules 4-6; the black colour forms at the costal margin a narrow streak to the base and at the distal ...
“The western population is at greatest risk of extinction, having declined by an estimated 99.9%, from as many as 10 million to 1,914 butterflies between the 1980s and 2021.
