Paederus dermatitis, medically known as dermatitis linearis, is a skin irritation resulting from contact with the hemolymph of certain rove beetles, a group that belongs to the insect order Coleoptera and the genus Paederus.

Other local names given to Paederus dermatitis include spider-lick, whiplash dermatitis, and Nairobi fly dermatitis.

Rove beetles do not bite or sting but cause skin irritations and blisters when accidentally brushed or crushed against the skin provoking them to release their coelemic fluid which contains a strong blistering chemical. The active agent in the coelemic fluid is commonly referred to as pederin, although depending on the beetle species it may be one of several similar molecules including pederone and pseudopederin.

"Blister beetle dermatitis," a term more properly used for the different dermatitis caused by cantharidin from blister beetles, is also sometimes used to describe paederus dermatitis caused by rove beetles.
