Crematogaster mutans is a socially parasitic acrobat ant. This photo shows a winged queen.
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, ParanĂ¡, Brazil
