They are referred to as predators or parasites. Generally, they will consume a variety of pests, providing general insect population control. They are important natural enemies and can have a significant impact on pest populations. Although the bite of a few spiders can cause a reaction in humans, they are usually harmless if not provoked. There are other types of lady beetle adults that are solid black, solid orange, or black with red spots.
Some species are quite tiny.
Lady beetle eggs are orange or yellow, spindle-shaped, and laid in groups. Ladybug larvae look somewhat like tiny black and orange alligators, totally different from the adults. They are usually found on plant foliage, near colonies of pest insects. They are often seen around foliage, but are also attracted to lights at night. The larvae are shaped somewhat like lady beetle larvae, but they usually are less brightly colored.
