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. The viceroy was named the state butterfly of Kentucky in 1990. [3]
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 ...
The hooded pitohui.The neurotoxin homobatrachotoxin on the birds' skin and feathers causes numbness and tingling on contact.. The following is a list of poisonous animals, which are animals that passively deliver toxins (called poison) to their victims upon contact such as through inhalation, absorption through the skin, or after being ingested.
In both caterpillar and butterfly forms, monarchs are aposematic, warding off predators with a bright display of contrasting colors to warn potential predators of their undesirable taste and poisonous characteristics. One monarch researcher emphasizes that predation on eggs, larvae, or adults is natural since monarchs are part of the food chain ...
Some feed on more toxic plants and store these toxins within themselves. The more palatable caterpillars thus profit from the more toxic members of the same species. [14] [16] Another important form of protective mimicry is Müllerian mimicry, discovered by and named after the naturalist Fritz Müller.
Toxic insects, primarily beetles, in the diets of these toxic birds are the most common sources for the bird’s toxicity. In the New Guinea bird species of Pitohui and Ifrita, the beetles of genus Choresine, natively known as nanisani, are pivotal food sources, and toxin sources, of these birds. [6]
The butterfly closely resembles the monarch butterfly (Danaus plexippus) of the Americas. The wingspan is 70 to 95 millimetres (2.8 to 3.7 in). Both sexes of the butterfly have tawny wings with veins marked with broad black bands. The male has a pouch on the hindwing. [4] [5] [6] The margins of the wings are black with two rows of white spots ...
Lepidoptera (/ ˌ l ɛ p ɪ ˈ d ɒ p t ər ə / LEP-ih-DOP-tər-ə) or lepidopterans is an order of winged insects which includes butterflies and moths.About 180,000 species of the Lepidoptera have been described, representing 10% of the total described species of living organisms, [1] [2] making it the second largest insect order (behind Coleoptera) with 126 families [3] and 46 superfamilies ...
