TED-Ed: The bizarre world of parasitic wasps | Miles Zhang

The video explores the fascinating and gruesome world of parasitoid wasps, showcasing their unique evolutionary strategy of using other animals as hosts for their offspring. It details how different wasps parasitize cockroaches, ladybugs, gall wasps, and caterpillars, often leading to the host's demise. The video highlights the diversity and complexity of parasitoid wasps, including their ability to manipulate host behavior and engage in polyembryony. Despite their small size, these wasps play a significant role in ecosystems and are a subject of ongoing scientific research.
