Everyone knows about wasps. They are known to be aggressive and vicious. Even more so when they are in a colony. I remember a terrible incident. At that time, I was still in my teens, and I was a naughty boy.
One time, I was chased by a gang of wasps. They were angry and eager to gang up on me. Their anger was justified because I had disturbed them. I was throwing a rock at their nest. Immediately, they scattered out and chased me like a thief. Their chase only ended when I threw myself into the river.
A wasp does not behave aggressively when alone or away from its colony. This little guy is an example. Instead of being aggressive, this little guy behaved shyly and hid behind the twig of the Mimosa plant. A wasp that is supposed to be vicious instead looks like a housefly :D
