Which insect is known for carrying large leaf fragments in rainforests?

The insect known for carrying large leaf fragments in rainforests is the leafcutter ant.

Leafcutter ants belong mainly to the genera Atta and Acromyrmex and are among the most recognizable rainforest insects. Workers cut pieces from leaves, flowers, and other plants, then carry the fragments back to their underground colonies. The leaves are not usually eaten directly; they are used to cultivate a specialised fungus that serves as the colony’s food.

A leafcutter colony contains several worker castes with different jobs. Smaller workers tend the fungus and care for the young, while larger workers cut vegetation and defend trails. Some ants also remove contaminants and produce antimicrobial substances that help protect the colony’s fungal garden.

The ants’ apparent strength is impressive: a worker may carry several times its own body weight. Their long, organised trails can strip foliage from plants, but leafcutter ants are also important ecosystem engineers because they move nutrients into the soil and influence rainforest plant growth.

They are often confused with termites, but termites feed on plant material and have a completely different social lineage.
