The largest European water insect Lethocerus patruelis, commonly known as giant water bug, can reach the impressive size of up to 8 cm in length. A recent study provides detailed information on karyotype and the reproductive system of the species. The study also presents a rare opportunity to see their vicious predatory practices, catching a giant water bug larva attacking and killing a small fish on video.
