This predatory behavior is very effective against the relatively large prey that the ants consume. Dejean and other researchers (2001) tested the limits of its effectiveness by exposing the ants to termites and grasshoppers, which are about 40 and 142.2 times the size of the worker ants, respectively. So a single "Allomerus decemarticulatus" worker restraining a grasshopper is about the equivalence of a 175-pound person holding down a struggling 25,000 pound object that is actively trying to escape. When the termites were exposed, each was captured by the ants; none got away. However, with grasshoppers, all were seized by at least one leg, but out of the 20 introduced, five were captured completely, 12 escaped but lost their leg that was clasped on to by the worker, and seven jumped away.
