European Harvestman
Phalangium opilioAlso known as Daddy Longlegs, European Daddy Longlegs
European harvestmen move across garden foliage and soil on eight delicate, thread-like legs, using their long second pair of legs as sensory antennae to probe their surroundings. Unlike true spiders, their fused body segments lack a narrow waist, and males feature prominent horn-like projections on their jaws used during courtship combat. They act as beneficial generalist predators in farmland and backyards, consuming soft-bodied pests like aphids, mites, and small caterpillars.
