Caddisworms are insects that are often seen in rivers and ponds.

Caddisworms play an important role in the river ecosystem.

I found a woodlouse in the garden.

His hobby is collecting insects.

This sand is very fine.

Ibis is my favorite character.

The pond in the park is very beautiful.

Mr. Ike is my best friend.

There is a beautiful pond in the park.

We often have picnics by the river on weekends.
