Like bees, ants organize their colonies based on social rank. It appears trap-jaw ants engage in antenna-boxing matches to dictate who guards the colony and who goes out into the world to forage.
Ants experienced life in groups, and fought wars against termites and one another, long before humans engaged in war and socialization themselves.
Formica ants, a type of ant also known as wood ants, are often conquered by certain parasitic ants. Once enslaved, they are more accepting of a more diverse colony, says a new study.
When yellow jackets sense an intruder, they emit chemical signals known as alarm pheromones that rouse colony members into defense mode and mark intrduders for attack.
An entomologist recently looked at the story behind matricide among social insects, which isn't the standard but sometimes happens. It turns out that a pretty intricate plot is behind it. Stand back, MacBeth.
