Adult Amblyopone ants cannot eat solid food and are incapable of the trophallaxis behavior that allows most other ant species to share food among nestmates. Instead, they have developed a novel way to feed themselves: consuming the hemolymph of nestmate larvae. Ants puncture vulnerable spots in the larval skin- as the ant on the left demonstrates- and lap up the drops of hemolymph. Interestingly, this odd behavior does not usually harm larvae. Many maturing larvae in a nest bear scars.
