Originally native to Italy, this fascinating arachnid expanded rapidly across Europe over recent decades, becoming a common sight in towns and cities. Unlike true spiders, harvestmen produce no silk or venom, making them completely harmless to humans! Males grow up to 6 millimeters with vibrant reddish-orange bodies and miniature horn-like structures on their jaws, while larger females (up to 8 millimeters) feature a lighter orange-brown tone with a dark, saddle-shaped pattern on their backs. Using their extra-long second pair of legs like sensitive antennae, they feel their way around while searching for small insects and decaying organic matter from June all the way into December.
