Where do poisonous insects store their venom

In fact, how do any toxic animals survive their own secretions?The answer is that they use one of two basic strategies:securely storing these compounds or evolving resistance to them.Bombardier beetles use the first approach.They store ingredients for their poison in two separate chambers.When they’re threatened, the valve between the chambers opens and the substances combine in a violent chemical reaction that sends a corrosive spray shooting out of the glands,passing through a hardened chamber that protects the beetle’s internal tissues.
