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 Oxytrigona. [6] [7] Wood ants from the genus Formica can spray formic acid on their prey or to defend the nest.
The ants inject formic acid into surrounding plants, killing small trees and shrubs. Members of the formic acid producing genus Formica are known for their citrus taste. [ 2 ] The Allegheny mound ant's appearance is very striking: both its head and thorax are red-orange; its gaster is black-brown.
The poison sprayed by Formica obscuripes consists of formic acid, eight straight-chain alkanes, a branched-chain alkane and five alkenes. The major component, formic acid, has been found to vary from 8 to 96% and average 73% of the volatiles in the secretion.

Formica is the type genus of the Formicidae, and of the subfamily Formicinae. [3] The type species of genus Formica is the European red wood ant Formica rufa. [1]
However, this species can fire/shoot a formic acid spray from its abdomen when under attack by other insects or attacking other insects. When the longhorn crazy ant (Paratrechina longicornis) bends its abdomen while aiming at an enemy insect, it is typically shooting its hard-to-see acid. These ants can be touched safely, similar to the ghost ants.
