Orchesella villosa
Shaggy Springtail, Slender Springtail
Orchesella villosa is a species of springtail in the family Orchesellidae, characterized by its slender body and shaggy appearance. Native to Europe and the Mediterranean region, it has been introduced to North America where it is considered invasive. The species has become a model organism for studying urban evolution, with research demonstrating microgeographic divergence in physiological traits among populations separated by less than one kilometer within cities.
