The Cuckoo Wasps are a colourful Family of wasp, noted for their parasitic behaviours. Their irridescent patterning is achieved by their microscopely structured surface, which interferes with the visibile light to give them a rainbow patterning. There are four sub-families, of which the Chrysidinae are the largest and best known. The female lays her eggs in the nest of a host species. The hatching larvae then devour the host's eggs or larvae, as well as their food source. These wasps cannot sting, with their ovipositor being designed for the placement of the eggs. When threatened, she will curl up into a tight ball, protecting her limbs and vulnerable regions with her sturdy exoskeleton.
