Kilpikirroksen

Kilpikirroksen is a Finnish term that translates to "shield bug" or "stink bug" in English. It refers to a group of insects belonging to the order Hemiptera, specifically the suborder Heteroptera. These insects are characterized by their hardened forewings, which are typically shaped like a shield and cover the membranous hindwings when at rest.

The most distinguishing feature of many kilpikirroksen is their ability to produce a foul-smelling liquid as a defense mechanism. This liquid, often referred to as "stink," is secreted from glands located in their thorax. The odor can deter predators and is a characteristic trait of the group, though the intensity and specific smell can vary between species.

Kilpikirroksen are found worldwide, inhabiting a wide range of environments, from forests and grasslands to agricultural fields and even urban areas. Their diet varies depending on the species, with some feeding on plant juices, while others are predatory and feed on smaller insects. Many species have a life cycle that includes egg, nymph, and adult stages. In some regions, certain species of kilpikirroksen can be considered agricultural pests due to their feeding habits on crops. However, many are harmless to humans and play a role in the ecosystem as both prey and predators.
