+Formic acid (from Latin formica 'ant'), systematically named methanoic acid, is the simplest carboxylic acid, and has the chemical formula \ch{HCOOH} and structure \ch{H-C(=O)-O-H}. It is an important intermediate in chemical synthesis and occurs naturally, most notably in some ants. Esters, salts and the anion derived from formic acid are called formates. Industrially, formic acid is produced from methanol.

+Formic acid is found naturally in insects, weeds, fruits and vegetables, and forest emissions. It appears in most ants and in stingless bees of the genus \textit{Oxytrigona}. Wood ants from the genus Formica can spray formic acid on their prey or to defend the nest. The puss moth caterpillar (\textit{Cerura vinula}) will spray it as well when threatened by predators. It is also found in the trichomes of stinging nettle (\textit{Urtica dioica}). Apart from that, this acid is incorporated in many fruits such as pineapple (0.21 mg per 100 g), apple (2 mg per 100 g) and kiwi (1 mg per 100 g), as well as in many vegetables, namely onion (45 mg per 100 g), eggplant (1.34 mg per 100 g) and, in extremely low concentrations, cucumber (0.11 mg per 100 g). Formic acid is a naturally occurring component of the atmosphere primarily due to forest emissions.
