Stenodema vicinum is a species of insect commonly known as the pale green stink bug or the green shield bug. Belonging to the family Pentatomidae, this species can be found in various regions of Europe, including the Mediterranean and parts of Asia.
The pale green stink bug is typically small in size, measuring around 8 to 10 millimeters in length. It possesses a flattened shape with a distinctive shield-like appearance, characteristic of many stink bug species. Its body is primarily green in color, though it may exhibit slight variations such as pale yellow or brown markings. The wings are well-developed and cover most of the abdomen.
Like other stink bugs, S. vicinum possesses a specialized glandular system that produces a foul-smelling secretion. This defense mechanism serves to deter potential predators and is released when the bug feels threatened or disturbed. The odor, often described as pungent and unpleasant, acts as a deterrent to predators.
The pale green stink bug primarily feeds on a wide range of plant materials, including leaves, stems, fruits, and seeds. It uses its mouthparts to pierce plant tissues and extract sap or juices. While it can occasionally cause damage to crops and garden plants, it is generally not considered a significant agricultural pest.
Due to its widespread distribution, the pale green stink bug serves as an important component of local ecosystems, participating in nutrient cycling and contributing to biodiversity.
