Hypolimnas misippus, the Danaid eggfly, [2] [3] mimic, [3] or diadem, is a widespread species of nymphalid butterfly. It is well known for polymorphism and mimicry . Males are in a singular form, appearing blackish with distinctive white spots that are fringed in blue.
Inter-sexual mimicry (a type of automimicry, as it is within a single species) occurs when individuals of one sex in a species mimic members of the opposite sex to facilitate sneak mating. An example is the three male forms of the marine isopod Paracerceis sculpta .
Mimicry is an adaptation by a species, called the mimic, making it resemble something else, called the model, with the effect of deceiving another species, the dupe. The three are not always all distinct, as mimicry can for example be within a species. [3] The adaptation is to the evolutionary advantage of the mimic.
Species 1 therefore gains n- a 1 n / a 1 +a 2 = a 2 n / a 1 +a 2 and species 2 similarly gains a 1 n / a 1 +a 2 in absolute numbers of individuals not killed. The proportional gain compared to the total population of species 1 is g 1 = a 2 n / a 1 (a 1 +a 2 ) and similarly for species 2 g 2 = a 1 n / a 2 (a 1 ...
The predatory species mediating indirect interactions between the mimic and the model is variously known as the [signal] receiver, dupe or operator. By parasitising the honest warning signal of the model, the Batesian mimic gains an advantage, without having to go to the expense of arming itself. The model, on the other hand, is disadvantaged ...
CA Intermediate is the second level exam, of a course in India, Chartered Accountancy. It has six subjects and over 7000 pages of study material that a student is expected to cover in the nine months study period allotted to them.
Examples include many moth, butterfly, and fish species that have "eye-spots". These are large dark markings that help prey escape by causing predators to attack a false target. For example, the gray hairstreak ( Strymon melinus ) shows the false head at its rear; it has a better chance of surviving an attack to that part than an attack to the ...
The mechanism provides a measure of protection for the mimic, as parasites and predators rarely attack their own species. The first described example of Gilbertian mimicry is the mimicking of Heliconius butterfly eggs by the leaf stipules of Passiflora plants. These are thought to protect the plant as the butterfly avoids laying eggs near eggs ...
