''Crematogaster scutellaris'' is a species of ants belonging to the family Formicidae subfamily Myrmicinae. ==Description== ''Crematogaster scutellaris'' can reach a length of about 8 mm in the queen, while the workers rarely exceed 5 mm. These ants have reddish head and black thorax and abdomen. The shape of the abdomen is characteristic, as it gradually narrows toward the apex. They raise menacingly their pointed abdomen when they are feeling attacked, emitting a small drop of pheromones from the rear end. The smell of the pheromone causes a general mobilization in the nest and any intruder is soon surrounded by a mass of aggressive ants.
