The green stink bug is a species commonly found throughout the country. It usually feeds in parks and gardens, but sometimes, it might visit us at home. Do not try to catch it with your bare hands. As the name suggests, when threatened, it releases a very unpleasant, irritating smell.

The green stink bug is commonly found in Europe and Asia. It can be spotted in forests, parks, gardens, and even balconies and terraces where its food sources grow. This insect prefers moist and shaded areas.

What does the green stink bug look like?

The green stink bug, Palomena prasina, grows about 1.5 centimetres long. Its body is oval and slightly flattened, and its intense green colour provides perfect camouflage among leaves. Interestingly, this insect can change colour depending on the season, turning brown in the fall. This makes the green stink bug a true master of camouflage.

The stink bug perfectly blends into the leaves of trees and shrubs, often making it difficult to locate. Thanks to its camouflage, the insect can feed on fruits such as raspberries, cherries, or berries. The green stink bug doesn't consume them entirely but sucks the juices from the inside, making their taste unpleasant.

The green stink bug feeds on plant juices, which can damage crops. However, its primary food sources are wild plants, so the damage it causes is usually minimal. Moreover, the green stink bug is a natural enemy of some plant pests like aphids and caterpillars, making it an ally to gardeners.

An odour that deters

We have already touched on the issue of colour, but it's also important to note the first part of this bug's name. It's not called the green stink bug without reason. When threatened, it secretes a substance with an intense, unpleasant smell designed to deter potential attackers. It's important to remember that it shouldn't emit a foul odour if not attacked, but the sharp smell can trigger an allergic reaction.

The insect can detect the smell of danger several meters away, and its intense odour persists even after death. Interestingly, the green stink bug is a master of not only camouflage and deterrence but also communication.

It can "talk" to other members of its species by transmitting vibrations through leaves. These extraordinary "messages" can serve as warnings against rivals or invitations to mate. Moreover, green stink bugs can carry out such conversations even in larger groups.

It’s worth remembering, however, that this bug can fly and may accidentally end up in our home. In such a case, it’s better to help it find its way out, as it may feel threatened, which would be unpleasant for our noses. However, it should not be touched as the smell will transfer to us.
