Last week we learned about mimicry. You may need to check a science book or on the web. Batesian mimicry and Mullerian mimicry are the two types of mimicry insects like to use. Batesian mimicry is when there are two insects that look the same and only one is not appealing to predators. An example would be a robber fly that looks like a wasp.
Mullerian mimicry is when two insects that are BOTH unappealing to predators look the same.
So if a bird eats one these insects and finds that it is bad tasting it will never eat either of the Mullerian mimics again. An example of this is the Monarch and the Viceroy butterflies. A lot of BugClub members knew this one. It works like a strong perfume that they can smell. Ants and termites use pheromone trails to show others the way to food, water, or back to the colony.
