Taxon Page Images:


Adult Stigmatomma 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 in the center demonstrates- and lap up the drops of hemolymph. (Stigmatomma oregonensis) Quincy, California, USA.
