Neolarra is a genus of cuckoo bees in the family Apidae.
Smaller than a grain of rice, these bees lay eggs in the nests of Perdita bees; the Neolarra egg hatches and the larva eats the egg and food store (of pollen[5]) intended for a Perdita larva.
[6] It is likely that, in order to hide them from the returning Perdita bee, the eggs are inserted into the walls of brood cells (underground chambers).
[5] In order to overpowers and kill the young Perdita egg or larva the Neolarra larva develops and uses a hard, sickle-shaped tooth.
