Mimicry

Mimicry of ants is a fairly common and widespread phenomenon involving a large number of ant and non-ant species. These include a range of insects from at least 10 orders as well as spiders from at least 9 families. Mimics can be found world-wide in all habitats where ants occur.

Mimicry can take two forms: myrmecomorphy and myrmecophily. Myrmecomorphy is a subset of ant mimicry which includes all species that resemble ants through convergence in morphological, behavioral, chemical, or textural characters. Myrmecophiles are those arthropods that associate closely with ants but do not necessarily resemble them (Kistner, 1982). Unlike most myrmecomorphic species, myrmecophiles are typically convergent in chemical and/or textural characters that facilitate a close relationship with their ant models (Holldobler, 1971). Some myrmecophiles are also myrmecomorphic, and these have been named Wasmannian mimics (Rettenmeyer, 1970) after the pioneering work of Wasmann (e.g. Wasmann, 1925).

Ants Mimicking other Ants
Within Madagascar, there are four species of Camponotus, Camponotus imitator, Camponotus jodina, Camponotus karaha and Camponotus longicollis, that mimic the general form and behavior of the Aphaenogaster swammerdami group, specifically Aphaenogaster bressleri, Aphaenogaster gonacantha, Aphaenogaster makay, Aphaenogaster sahafina and Aphaenogaster swammerdami. These Camponotus mimics are often seen foraging with workers of Aphaenogaster, but potential benefits for Camponotus have not been studied (Csosz et al., 2021).
