Formicidae Checklist: Ants

on
6 May 2020

Ants are eusocial insects belonging to the family Formicidae, and have been recorded on every continent on earth except Antarctica. Ants thrive so well in most environments that they may form up to 25% of terrestrial animal biomass[1].

Ants have distinctively elbowed antennae, and have slender waists formed by nodular structures. They form colonies ranging in size from dozens to millions of individuals. Each colony would typically consist of at least one fertile queen, mostly workers, soldiers, and various other castes.

Most identifications here were made with reference to keys and photographs on AntWiki, as well as help from kind folks from the Myrmecologists Facebook group.

All photos are of live subjects shot in the field. Click on individual photos for larger views and views from other angles. As specimens were not collected, identifications were done based purely on photographs and may not be 100% accurate.

This page will be updated regularly, please let me know if you spot any mistakes.

Trophobiosis

Trophobiosis is common with ants where they exhibit a symbiotic relationship with other invertebrates such as sugar-excreting insects. The insects supply food in the form of their sugary excrement, while the ants offer protection from predators.

Cordyceps Fungus

Ophiocordyceps is an insect-pathogenic fungus, also known as cordyceps fungus, that infects ants and controls their brains. Infected ants would climb to the tallest point, often the tip of tall grass or leaves, and die there. This aids the fungus in dispersal and self-propagation when the fungus grows its fruiting body out to disperse spores.

Ant Predators

Many invertebrates are specialist ant predators. Here are some examples.

Ant Mimicry

Several invertebrates mimic ants. Batesian mimicry is the form where mimicking an ant reduces the risk of predation, as ants are typically unpalatable and aggressive to potential predators.
