Most butterflies lay their eggs on plants: on the top or bottom of leaves, on the flowers, on twigs, in the chinks of bark, or on the plant stalk. Some butterflies lay their eggs near the plant: on dry grass stems, dead leaves, or on soil. By laying their eggs on or near plants, the newly hatched caterpillars will have something to eat.

Butterflies lay eggs that turn into caterpillars that turn into butterflies.
Most butterflies don't lay their eggs in garbage. They typically lay their eggs on the plant that their caterpillars will feed on. Monarchs butterflies lay their eggs on milkweed plants.
