The Scariest Types of Insects in the World

List Rules
Vote up the most terrifying species of insect you hope to never encounter in the wild.

One of humanity's most primal fears is that there is something crawling up your back right now. Seriously, you might want to check that out because a fear of insects resides in just about every one of us. There's good reason for that: there are some insect species who have absolutely no problem causing us real harm and even killing us!

Humans may think themselves the dominant lifeforms on the planet, but there are millions of species of insect species in every nook and cranny of the globe. Some of the scariest types of insects, which attack humans, serve up a healthy dose of fear.

The main problem with most insects is that you don't have to worry about one insect that attacks humans, you have to worry about a swarm of nasty bugs. You might be able to swat one pesky bug, but 10,000 of them? That's a different story. Some of the scariest bug species around are rather ugly, which is one of the reasons people fear and despise them, while others are surprisingly beautiful. Despite their appearance, there are several species of insects that are dangerous to humans and should be avoided at all costs—and many are found on this list.
