Does this grow into a stink bug?

The Common green stinkbug or Palomena prasina is a common bug. You can find it in large parts of Europe, North Africa and the temperate parts of Asia. The bug has adapted to all kinds of biotopes such as forests, grasslands with suitable shrubs, marshes, gardens and parks, as long as food plants grow.


The bugs locate each other by creating vibrations with the help of muscles that make the body vibrate. These vibrations are transmitted by the plant, so that other bugs on the plant know that a partner is being sought. Pairing is done by linking the abdomen together. In this way they keep walking around for a while. In June, eggs are laid on the underside of leaves. Palomena prasina is going through a metamorphosis. With every shed, five in total, it looks more and more like the imago. It is amazing to see that during shedding, the animal even leaves the outer layer of the eyes behind. When the adult insect or imago is fully developed, it can again focus on reproduction. When the winter starts, the bug will hibernate. During the hibernation, its green color changes to a brown to red-brown protective color.

All bugs of this kind have a proboscis. They live on vegetable juices and gather this by sucking out plant leaves such as nettle, feather thistle, rose family bush, hazel and black alder as well as fruit such as apple, blackberry, raspberry and pear, with blackberry being preferred.


For fruit and hazelnut growers, the presence of the bug is undesirable. They are also called stinkbug for good reason. When eating, the animals leave behind a nasty weary smell that does not benefit the taste of the plant parts visited. This repellant comes from glands on the side of the chest piece. The substance that they excrete is not only intended to keep away enemies such as carnivorous predators, blackbirds, flies and larvae from other insects, but also to protect the body against bacteria and fungi.

With thanks to my wife Geertje who found the material for the video in our garden at the bottom of a rose leaf.
