Coloured scanning electron micrograph (SEM) of a jewel, or emerald cockroach, wasp (Ampulex compressa) larva. The female of this wasp stings a cockroach and disables it before taking it to her burrow and laying one or two eggs on it. When hatched the larva feeds on the cockroach for 4 to 5 days before chewing its way into its abdomen. The larva feeds on the cockroach's internal organs, eventually killing it after about 8 days. It then forms a cocoon in the cockroach's body as it enters the pupal stage. Magnification: x80 when printed at 15cm wide.
