10 most terrifying insects in the world (With Pictures)

4. Hornet

Hornets are the largest eusocial wasps; some species can reach up to 5.6 cm in length. The true hornets make up the genus Vespa and are distinguished from other vespines by the width of the vertex, which is proportionally larger in Vespa and by the anteriorly rounded gasters. Hornet stings are more painful to humans than typical wasp stings because hornet venom contains a large amount (5%) of acetylcholine. Individual hornets can sting multiple times; unlike typical bees, hornets and wasps do not die after stinging because their stingers are not barbed and are not pulled out of their bodies.
