Wasp that in my tree?

@psycoskunk Said

Mud wasps are nasty bastards. I haven't gotten stung by one, but I've seen the results.

If you want a really scary wasp, here's the Tarantula Hawk Wasp.



Fun fact: They have the second most painful sting in the insect world, the first being the bullet ant.



It's how insects communicate. Every wasp, bee and ant species use different pheromones for different things, mainly to find food or to defend the nest. Yellow jackets release a pheromone when they're killed, alerting the nearby hive about a potential attacker, for instance.
