What is the processionary moth

The processionary moth is a very common moth that can be easily encountered during the spring period , especially in the presence of young specimens of pines and oaks , trees on which the processionary nests. 

There are about forty species of processionary moth and, among these, the most widespread is the Thaumetopoea pityocampa , or pine processionary moth.
In Italy the processionary is present from north to south, not only on pines and oaks but also in beech woods or where there are birch , chestnut and other trees , especially exposed to the sun. Unfortunately, it is not uncommon to meet the processionary moth even in inhabited centers , in gardens and parks.

The common name derives from the habit these insects have to move in orderly rows when they are on the ground or on the trunks of trees , as in a sort of procession.

The adult processionary moth turns into a harmless moth , but in the larval stage it is a caterpillar that can be very dangerous for trees and especially for dogs, cats and small children.

The caterpillar of the processionary moth is easily recognizable , not only due to the habit of moving in procession, but above all because its body – about four centimeters long – is covered with a thick hair that serves to defend the larva from any predators.

The danger is represented precisely by the presence of stinging hairs that can cause even very serious reactions to the skin , eyes , mucous membranes and respiratory tract of those who come into contact with them. 

The risk of encountering the processionary moth is greater in spring , when the larvae leave the host plant to bury and mature, and then emerge in the summer in the form of moths. 

Processionary: the risks for dogs

We know that dogs usually explore the area by smelling the ground and, for this reason, they can easily come into contact with the processionary moth during the spring months during walks in the pine forest and in the woods, but also in their own garden.

If a dog comes into contact with the stinging hairs of the processionary moth, it can show more or less severe symptoms depending on the type of exposure . Among the first signs is increased salivation, followed by vomiting and an enlarged tongue. The parts that have been in contact with the processionary may go into necrosis and cause the loss of tissue at the level of the tongue or nose. In the most serious cases , when the contact has been prolonged or if the processionary moth is swallowed, it can unfortunately lead to the death of the animal. 

In order not to make the animal run unnecessary risks, it is therefore essential to avoid the places where you could meet the processionary and pay the utmost attention to its behavior. When accompanying him for a walk, it is always advisable to keep him on a leash .

If, on the other hand, you have a garden or land, you must make sure that there are no processionary nests and, if you should observe the presence of caterpillars, contact specialists who can safely disinfect the area .

If, despite the precautions, the dog nevertheless comes into contact with the processionary moth, you should immediately contact your veterinarian .

Processionary: the risks for children

The processionary moth also poses a danger to humans , not just dogs. Clearly, children are more at risk : by playing they can come into contact with the processionary moth, touch it and then perhaps bring their hands to their mouths. 

Contact with the stinging hairs of the processionary moth can lead to allergic reactions, irritation and inflammation affecting the skin, mucous membranes, eyes and airways. 

If a child comes into contact with the hair of the processionary moth, it is advisable to wash the affected areas with plenty of water and consult the pediatrician .
