ARMADILLIDIUM VULGARE Meaning and
Definition
-
Armadillidium vulgare, commonly known as the common pillbug or woodlouse, is a species of terrestrial crustacean found in many parts of the world. It belongs to the family Armadillidiidae, which consists of approximately 40 species of pillbugs.
Armadillidium vulgare typically measures around 12 to 18 millimeters in length and has a distinctive segmented body that is broadly oval in shape. It is characterized by its ability to roll itself into a tight ball when threatened, offering protection with its hard exoskeleton. The coloration of Armadillidium vulgare is variable, ranging from grayish to brownish tones, often with mottled patterns.
These crustaceans are commonly found in damp and dark environments, especially under decaying organic matter such as fallen leaves, logs, rocks, or in soil. They feed on decomposed plant material, small insects, fungi, and algae. Armadillidium vulgare prefers environments with high humidity levels to prevent desiccation, but can also tolerate drier conditions for a certain period.
The species has a broad distribution across Europe, North America, and other parts of the world, often introduced accidentally through human activities. Armadillidium vulgare plays a vital role in the ecosystem by contributing to nutrient cycling through their feeding habits and aiding in the decomposition process. In addition, they serve as a source of food for other organisms, including birds, reptiles, amphibians, and small mammals.
Etymology of ARMADILLIDIUM VULGARE
The word "Armadillidium vulgare" is the scientific name for a common species of pillbug or woodlouse. Its etymology can be broken down as follows:
1. Armadillo: The name "armadillidium" is derived from the Spanish word "armadillo", which means "little armored one". This term is used due to the pillbug's resemblance to an armadillo with its rigid exoskeleton.
2. Vulgare: The term "vulgare" comes from the Latin word "vulgaris", meaning "common" or "ordinary". It is added to indicate that this particular species of pillbug is widely distributed and frequently encountered.
Therefore, "Armadillidium vulgare" suggests a common woodlouse with armadillo-like features.
