Both the adult and larvae are considered useful insects since they are major predators of aphids, scale insects, or mites which are pests in gardens, agricultural fields, orchards, and similar places. Within the colonies of such plant-eating pests, they will lay hundreds of eggs, usually underneath the leaf, well protected from the predators. The eggs are small (about 1 mm) and spindle-shaped. When the larvae hatch, they will commence feeding immediately. Additionally, female may lay 10-15 eggs around a place that the babies can find food once they hatch. Once the metamorphosis is complete, the larvae skin will split open. That is when the full grown ladybug will emerge; however, it will not look like the normal ladybug that we are used to seeing. It will look pale or soft and pink for a few hours until the actual shell hardens. While the shell is getting hard, it gains pigments, which is why the ladybug turns red. Adults can live for weeks or months, depending on the location, availability of prey, and time of year. These beetles have multiple generations per year.
