Opilio canestrinii is a species of harvestman. Males reach a body length of up to 6 mm, females up to 8 mm. While males are yellowish brown to reddish, the color is lighter in females. Males have dark legs, but yellow coxae and "knees"; the legs of females show alternatingly light and dark rings. The back of females sports a dark saddle-like pattern with a light longitudinal stripe in the middle. Adults can be found from June up to December. O. canestrinii probably originates from Italy, but has invaded central Europe since the late 1970 and has since almost everywhere replaced the similar O. parietinus. It is most often found on house walls. Order: Opiliones, Family: Phalangiidae.
