Ants produce formic acid, also known as methanoic acid, which is the simplest carboxylic acid. It's the chemical responsible for the stinging sensation when an ant bites. The name "formic acid" originates from the Latin word "formica," meaning "ant."
Formic acid was first discovered in the 17th century by English scientist John Gray, who isolated it from the distillation of ants.
Fun fact: Formic acid is also produced by some other insects, like bees and wasps, although in lower concentrations.
