We all know how ants forage for food. A bunch of workers are sent out randomly, then, upon finding some delicious munchie, each worker lays a chemical trail back to her nest in the hopes that other workers will follow suit. Whether or not nest mates do in fact reinforce a given trail is dictated largely by an emergent, semi-random selection process involving factors like the evaporation rate of trail pheromones, distance of a food source from the nest, and the size of the food source. So, that’s how all ants forage for food. Except it’s NOT!
Sometimes, The New York Times is depressingly anti-ant. Other times, it produces excellent ant-friendly content such as this video […]
Ants are all kinds of smelly, and a recent study in PNAS advances our understanding of the molecular and […]
The reproductive system of most ants is pretty freaky, by human standards. Unlike in our species, where all individuals have a diploid set of chromosomes, nearly all ant species utilize a “haplodiploid” system in which females are diploid and males are haploid, with only one chromosome for each chromosomal site. So, in order to produce males, a queen lays unfertilized eggs, while in order to produce females, the eggs must be fertilized.
This is an extrafloral nectary: Extrafloral nectaries, or “EFNs”, are little sources of sugar and nitrogen produced to […]

Polydomy. It’s a thing. It’s a thing where a single ant colony occupies completely separate nesting chambers rather than a single nest site. Polydomy, in creating a more distributed nest structure, has been theorized to increase foraging efficiency and enhance acquisition of a more diverse set of resources. Yet, despite the prevalence of hypotheses and theoretical work relating to polydomy, little work to date has experimentally tested the impact of polydomy on foraging efficiency.
Fungus-farming ants (the “attines”) are one of the most widely recognized groups of ants, particularly in the form of leaf-cutter ants. They even feature prominently at the beginning of the best classic Disney movie,
