The wasp species Dinocampus coccinellae. When the female is ready to lay an egg, she injects her stinger into a ladybug and injects an egg and chemicals into it. When the larva hatches, it feeds on the chemicals inside the ladybug and grows. Then it squirms out of a chink in the ladybug's exoskeleton and forms a cocoon between the ladybug's legs. Hypnotized, the ladybug will protect the pupa by thrashing its legs at predators until the pupa uses its mandible to open the cocoon and fly away, killing the ladybug along the way.
