Ancistrocerus gazella, a predatory wasp which feeds on lightbrown apple moth larvae

 

This solitary wasp (Eumenidae) builds tubular nests consisting of a series of cells in which the female lays a single egg. Each cell is stocked with late stage caterpillars as food for the hatching wasp larva. The caterpillars in each cell are often of only one or two species, although this wasp collects larvae of at least nine families. There have been exaggerated reports of the value and importance of this wasp for leafroller control. Research in Central Otago orchards has shown across a range of locations that lightbrown apple moth comprises only 1-4% of its prey.
