Several genera of myrmicine ants, including Crematogaster, attach intermediate-age larvae to the walls and ceiling of the brood chamber. These larvae have long, anchor-shaped hairs along their backs that hook into the substrate like velcro. Morretes, Paraná, Brazil
The long spines, slender waist, and exaggerated gaster render Crematogaster nigropilosa one of the most readily recognizeable acrobat ant species in South America. Morretes, Paraná, Brazil
