Extensive Field Observations Throw Light on the Evolution of Mimicry in Camponotus lateralis (Hymenoptera: Formicidae)

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
Camponotus lateralis (C, D) mimics regional color morphs of Crematogaster (A, B). Field trips brought insights into ecology, trail sharing, sexual reproduction, colony foundation, nest defense, and predation pressure of this mimetic ant. We found that the mimicry is Batesian and suggest several preadaptations for its evolution.
