Thaumetopoein is one of the soluble proteins in the stinging hairs of caterpillars of various types of processionary moth (Thaumetopoeinae). The protein, made up of two subunits, is regarded as the nettle poison of the fine stinging hairs. If they come into contact with barbs, these can get stuck in the human skin and cause itching, swelling and occasional asthma attacks. The dermatosis caused by thaumetopoein is known as caterpillar dermatitis . In addition, allergic reactions to other stinging hair proteins are known.

In Central Europe, caterpillar dermatitis is mainly caused by oak processionary moth ( Thaumetopoea processionea ), as well as pine processionary moth ( Thaumetopoea pinivora ); the heat- loving pine processionary moth ( Thaumetopoea pityocampa ) occur mainly in the Mediterranean area. According to a study from 1986, the thaumetopoein of the pine processionary moth is a histamine- releasing protein with a molecular weight of 28 kDa , which consists of two subunits (13 and 15 kDa). A study from 2006 showed that allergic reactions to various proteins in this butterfly are possible in children.
