Experiments of this type have shown the selective advantage of resting on a background where the insect is cryptic in the peppared moth (Biston betularia), caterpillars of the pine ...
Many types of polymorphism can be seen in the insect order Lepidoptera. Polymorphism is appearance of forms or "morphs" differing in colour and number of attributes within a single species. In Lepidoptera, polymorphism can be seen not only between individuals in a population, but also between the sexes … See more Genetic polymorphism occurs when the morphs are a result of genetic determination only. The extreme case of genetic polymorphism is that of the papilionid great Mormon (Papilio memnon), where four male … See more Geographical polymorphism is where geographical isolation causes a divergence of a species into different morphs. A good … See more Batesian and Müllerian mimicry complexes are commonly found in Lepidoptera. Genetic polymorphism and natural selection give rise to otherwise edible species (the mimic) … See more Sexual dimorphism is the occurrence of differences between males and females in a species.

WebA distinguishing feature of insects is their capacity for flight. Indeed, the evolution of flight is thought to be a key factor responsible for their enormous evolutionary success (Roff 1990). However, many insects have secondarily evolved flightlessness and many species are polymorphic for this trait. tactless peopleWebIn wing-polymorphic insects, wing morphs differ not only in dispersal capability but also in life history traits because of trade-offs between flight capability and reproduction. When the fitness benefits and costs of producing wings differ between males and females, sex-specific trade-offs can result in sex differences in the frequency of long-winged individuals. tactless vs diplomaticWebApr 10, 2024 · We measured mitochondrial function of fat body tissue across early adulthood of long-winged and short-winged crickets from two species of wing … tactless significatoWebSep 8, 2024 · The extraordinary success of social insects is partially based on division of labour, ...
