Formic acid (from Latin formica 'ant'), systematically named methanoic acid, is the simplest carboxylic acid, and has the chemical formula HCOOH and structure H−C(=O)−O−H. It is an important intermediate in chemical synthesis and occurs naturally, most notably in some ants.
They have large mandibles, and like many other ant species, they are able to spray formic acid from their abdomens as a defence. [3] Formic acid was first extracted in 1671 by the English naturalist John Ray by distilling a large number of crushed ants of this species. [8] Adult wood ants primarily feed on honeydew from aphids.
Wood ants typically secrete formic acid; F. rufa can squirt the acid from its acidopore several feet if alarmed, a habit which may have given rise to the archaic term for ant, "pismire", and by analogy its American equivalent "piss-ant".
A black drongo in a typical anting posture. Anting is a maintenance behavior during which birds rub insects, usually ants, on their feathers and skin.The bird may pick up the insects in its bill and rub them on the body (active anting), or the bird may lie in an area of high density of the insects and perform dust bathing-like movements (passive anting).
The team also found simple molecules of formic acid, which causes the burning sensation associated with ant stings, as well as sulfur dioxide, methane and formaldehyde.
Uniquely, the tawny ant also uses formic acid as an antidote against the venom alkaloids of the fire ant (known as solenopsins). The venom alkaloids of fire ants have been demonstrated to be strongly paralytic against competitor species, [14] thus the tawny crazy ant may have developed a resistance by acid-immobilisation of the venom toxins.
When ants bite humans, it grabs the skin and also sprays a compound called formic acid, Frye explains. Ant bites tend to be small, swollen bumps that appear in clusters, Kassouf says.
Formica sanguinea, or blood-red ant, is a species of facultative slave-maker ant in the genus Formica characterized by the ability to secrete formic acid. It ranges from Central and Northern Europe through Russia to Japan, China, the Korean Peninsula, Africa and also the United States. [1]
