While it's tempting to lump all hornets together under "the absolute worst" insect category, there is one species that stands above the rest -- the giant Japanese hornet. These things are massive, merciless killing machines. <br /> <br />They primarily prey on colonies of docile Japanese bees, eating their honey and larvae. Incredibly enough, it only takes a handful of these suckers to wipe out an entire honey bee colony -- a sad fact that beekeeper Sakamoto Ryouta learned back in 2014. Luckily, he had already set a trap for the giant hornets, but it still wasn't enough to stop the attack. <br />Considering that without honey bees, we could lose "70 of the around 100 crop species that feed 90% of the world," these hornets are effectively killing our food source. Can't we all just get along?!
