Müllerian mimicry: butterflies — 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.

A mimicry ring is a group of unrelated species—often including insects such as butterflies, beetles, true bugs, and spider wasps—that share the same conspicuous warning coloration.1

These rings are primarily associated with Müllerian mimicry, a phenomenon where multiple noxious or inedible species evolve to resemble one another. By adopting a common appearance, these species simplify the warning signals that predators must learn to recognize, thereby reducing the overall loss to predation for all members of the group. This strategy relies on the principle of signal standardization, which suggests that maximum protection is achieved when all individuals in the ring employ the same signal.12

Mimicry rings are often found in specific geographic regions, such as South America, and may also include Batesian mimics, which are palatable species that gain protection by imitating the appearance of the unpalatable members of the ring.1
