Detached hairs can also be inhaled and the upper respiratory tract can be affected producing dyspnoea or laboured breathing. Injuries to the eye have been recorded, resulting in conditions such as nodular conjunctivitis and, less commonly, permanent damage to the cornea. In the case of a mistletoe browntail caterpillar infestation, large numbers of school age children have been known to become affected after sitting under infested Eucalyptus trees, or as a result of disturbing leaf litter and bark at the base of the trees where the caterpillars have rested or pupated.

Laboratory Diagnosis. Accurate identification is essential in treating and controlling caterpillar infestations. This should be undertaken by experienced staff, with the use of light microscopy and taxonomic keys. Treatment and Control. To treat irritations as a result of urticating caterpillars, remove all affected clothing and apply a piece of adhesive tape to each of the affected areas, then pull the tape off immediately. This will remove some of the hairs and irritants and reduce the full impact of the irritation.

The use of analgesics, creams, antihistamines and lotions with steroids will also assist in relieving the symptoms. Avoid handling any hairy caterpillars or material with which they have been in contact. Suitable protective clothing, including eyewear and gloves should always be worn when handling these insects.

Many infestations will die out either through predation or when all food sources are exhausted. Caterpillars change into new skins as they grow Investing a bigger chunk of your resources into all that hair-growing comes with tradeoffs more hair-boosting resources equals fewer resources for other bodily needs.

That's why Sugiura and his colleagues are investigating whether hairy caterpillars develop at a slower pace than their smoother cousins. But it's not as if hairiness is the caterpillar world's only defensive measure. Caterpillars use camouflage, they lurk in hideouts, they mask their smells, escape down silk threads, emit foul chemicals — the list goes on.
