Compound Nesting

Sometimes two different species of insects live close together, side by side. The two insect groups might even share the same home. But the two species often are different enough that they do not have to compete for the same resources, and therefore they can avoid conflict. This is known as compound nesting. Compound nesting actually provides advantages to both species: because living closely together can result in a specific benefit to each group, benefits that increase both species‘ chances of survival

Now listen to part of a lecture in a biology class.

Professor:

Okay, so, for example, there are these two different types of ants in Africa that share space in this way, living inside a hollow tree branch.

And one of these types of ants is very small. And the other type is much bigger. So they are different. And what’s interesting is that the bigger ants collect food and bring it back to the hollow tree branch and eat it there, but some of the pieces of food end up scattered around, small bits of waste that the bigger ants don’t eat. And the tiny ants go around and eat these leftover scrapes of food. So the tiny ants get their food this way, from the scrapes left behind by the bigger ants, and they don’t have to go out to collect their own food.
