Certonotus fractinervis is a parasitic wasp found in New Zealand, one of only two species of Labeninae found in New Zealand. It preys on the elephant weevil.
Description
Certonotus fractinervis is the largest endemic wasp in New Zealand. It has three long ovipositors.
Ecology
Certonotus fractinervis lays its eggs exclusively on the larvae of the elephant weevil. It bores into trees using its ovipositor to lay its eggs on the larvae.
Occasionally, adults may feed upon water droplets that have gathered on fungus, which may be a source of sugar.
