What type of wasp eat tree leafs?

Answer 1

The type of wasp that primarily feeds on tree leaves is the leafcutter wasp, particularly species in the genera Megachile and Atta. These wasps cut and remove pieces of leaves to use as nesting material or to cultivate fungus, which serves as food for their larvae. While they don't consume the leaves directly, their activity can lead to significant defoliation of trees. Other wasps, like certain species of paper wasps, may also feed on plant material but are less associated with leaf-cutting behaviors.
