Batesian mimicry is a form of mimicry where a harmless species has evolved to imitate the warning signals of a harmful species directed at a predator of them both. It is named after the English naturalist Henry Walter Bates , who worked on butterflies in the rainforests of Brazil.
This polymorphism is seen in Papilio dardanus, the African swallowtail butterfly, whose females have three different morphs for wing color pattern: a black-and-white pattern for Batesian mimicry, a black-and-yellow pattern that resembles the males of the species, and a pattern with orange patches that resembles the elderly males of the species ...
Comparison of Batesian and Müllerian mimicry, illustrated with a hoverfly, a wasp and a bee. In Müllerian mimicry, two or more species have similar warning or aposematic signals and both share genuine anti-predation attributes (e.g. being unpalatable), as first described in Heliconius butterflies. [53] This type of mimicry is unique in ...
Mimicry is a form of defense which describes when a species resembles another recognized by natural enemies, giving it protection against predators. [2] The resemblance among mimics does not denote common ancestry. Mimicry works if and only if predators are able to learn from eating distasteful species.
Sesiidae are characterized by their hymenopteriform [a] Batesian mimicry, frequently of identifiable species. [2]: 11, 16 Most species of Sesiidae have wings with areas where scales are nearly completely absent, resulting in partial, marked transparency. [2]: 11 Forewings are commonly elongated and narrow in the basal half.
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]
Such female-limited Batesian mimicry is not unique to this species, even in the genus Papilio. For instance Papilio memnon shows a similar case of polymorphism in females. [23] Similarly, male mimicry has been observed in another insect, a damselfly Ischnura ramburii which also appears to have evolved camouflage to avoid sexual coercion by ...
Their black body has two white spots on the abdomen and their transparent wings have a distinctive black pattern. The tiger bee fly may be mistaken for a large bee due to its coloration and size. Their bee mimicry (an example of Batesian mimicry ) helps them avoid potential predators.
