Close-up of a Caligo wing. The underwing pattern is highly cryptic. It is conceivable that the eye pattern is a generalized form of mimicry. It is known that many small animals hesitate to go near patterns resembling eyes with a light-colored iris and a large pupil, which matches the appearance of the eyes of many predators that hunt by sight. [5]
Butterfly eyespot morphology appears to be the result of the evolution of an altered version of the regulatory circuit which patterns the wings of other insects. This rogue regulatory circuit is able to pattern both the anterior and posterior eyespots independent of the usual anterior/posterior wing compartmentalization restrictions seen in the ...
Limenitis arthemis, the red-spotted purple or white admiral, is a North American butterfly species in the cosmopolitan genus Limenitis.It has been studied for its evolution of mimicry, and for the several stable hybrid wing patterns within this nominal species; it is one of the most dramatic examples of hybridization between non-mimetic and mimetic populations.
Piedra Herrada, Mexico. The monarch butterfly or simply monarch ( Danaus plexippus) is a milkweed butterfly ( subfamily Danainae) in the family Nymphalidae. [ 6] Other common names, depending on region, include milkweed, common tiger, wanderer, and black-veined brown. [ 7] It is among the most familiar of North American butterflies and an ...
The colourful patterns on many butterfly wings tell potential predators that they are toxic. Hence, the genetic basis of wing pattern formation can illuminate both the evolution of butterflies as well as their developmental biology. The colour of butterfly wings is derived from tiny structures called scales, each of which have their own pigments.
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 ]
Caterpillar of the subfamily Arctiinae. Eggs of the buff-tip ( Phalera bucephala ), a notodontid moth. The external morphology of Lepidoptera is the physiological structure of the bodies of insects belonging to the order Lepidoptera, also known as butterflies and moths. Lepidoptera are distinguished from other orders by the presence of scales ...
Zerene eurydice, the California dogface butterfly, belongs to the family Pieridae and is a sister genus to Colias. [2] The Zerene eurydice and the Colias both share the "characteristic of having yellow-orange and black wing coordination." [3] Additionally the,"Colias and Zerene eurydice males have bright UV patterns on their wings."
