Larval hemolymph feeding is a behaviour trait found in the queens of some species of ant.
In colonies of the Amblyopone silvestrii the queens feed on the hemolymph (or insect blood, also spelt haemolymph) of their larvae when food is not available.
In one species, Myopopone castanea, worker ants consume larval hemolymph.
On the other hand, the foundresses suppress larval hemolymph feeding (LHF) when prey is available, allowing them to rear the first workers more swiftly.
The nondestructive form of cannibalism can be regarded as a nutritive adaptation related to: (1) the lack of social food transfer in this species, and (2) its specialized predation on large sporadic prey (centipedes).
