The ladybug, or lady beetle, is considered a beneficial bug in the garden ecosystem.

The ladybug helps to control aphids, and their bright red color helps to ward off predators such as bigger insects or birds. Other beetles can be found such as rove beetles and ground beetles.

4. Bring the students back to the classroom to draw a ladybug.

5. Have them label their drawings with the parts of the ladybug specifically (abdomen, antenna, head, wings, legs).
