Insect Life Cycle and Metamorphosis

The video explores the life cycle of insects, focusing on the transformation from egg to adult. It explains the four-stage life cycle of butterflies and moths, including egg, caterpillar, pupa, and adult stages, and contrasts it with the three-stage life cycle of insects like cockroaches and grasshoppers, which lack a pupa stage. The concept of metamorphosis is introduced, highlighting the complete transformation in four-stage cycles and the incomplete transformation in three-stage cycles. Students are encouraged to study and document insect life cycles around them.
