Caterpillars mimic one another for survival
Date:12/16/2011

tageous since they attract predators, but advantageous for attracting mates. Once established, bright colors might then be modified by natural selection for mimicry, another possible reason why mimicry seems to evolve much more frequently in adults than in caterpillars."

However, Sourakov believes mimicry is more common in caterpillars than scientists realize, but may receive less attention because larvae must be raised to adulthood to identify mimicry complexes, a process that takes weeks of lab work. Also, few collections of immature stages are maintained, and colors are not as well preserved in caterpillars.

"We know mimicry is an important ecological process for several species of animals, and I hope this study will give people incentive to further research immature stages of insects," said Andre Victor Lucci Freitas, a professor in the Instituto de Biologia at Universidade Estadual de Campinas. "We need to remember in most insects, immature stages are the most abundant."
