The Striped Bug, scientifically known as Graphosoma lineatum, is a species of shield bug belonging to the family Pentatomidae. It is also commonly referred to as the Italian Striped-Bug or Minstrel Bug. These bugs are easily identifiable by their striking red and black striped markings on their shield-shaped bodies, which serve as a warning to predators of their foul taste and defensive capabilities.
Here are some key features and characteristics of Graphosoma lineatum:
- Coloration: The most distinctive feature of Graphosoma lineatum is its bold red and black stripes running longitudinally on its body. These stripes serve as a form of aposematic coloration, warning potential predators of their toxicity.
- Body Shape: Like other shield bugs, Graphosoma lineatum has a shield-shaped body, which is typical of insects in the order Hemiptera.
- Size: They are relatively small insects, typically ranging from around 9 to 12 millimeters in length as adults.
- Habitat: These bugs are commonly found in various habitats across Europe, particularly in areas with abundant vegetation and suitable conditions for their preferred host plants.
- Diet: Graphosoma lineatum primarily feeds on the sap of plants belonging to the family Apiaceae (formerly known as Umbelliferae), which includes species like wild carrot, fennel, and parsley.
- Lifecycle: Like other shield bugs, Graphosoma lineatum undergoes incomplete metamorphosis, with three life stages: egg, nymph, and adult. They lay their eggs on the host plants, and the nymphs resemble smaller versions of the adults but lack fully developed wings.
Graphosoma lineatum is not considered a significant pest and is generally harmless to humans. In fact, they can even be beneficial in controlling certa
