mimicry
Heliconius butterflies demonstrating Müllerian mimicry, a form of mimicry where one or more species exhibit closely similar warning systems. In this case, wing patterning and coloration among the species appear very similar.
Philippine cockroaches of the genus Prosoplecta utilize Batesian mimicry to resemble ladybird beetles (Coccinellidae), which are inedible and often feature prominent, spotted coloration.1
To achieve this resemblance, Prosoplecta cockroaches have undergone profound physical modifications. Most notably, they simulate the short, rounded body shape characteristic of ladybird beetles by rolling and folding their large hind wings in a manner that is unparalleled among other insects. By mimicking these well-protected beetles, the harmless cockroaches gain a survival advantage, as predators often mistake them for their noxious models and avoid attacking them.12
