All lady beetles eat insects, as well as nectar and pollen, making them beneficial insects. They consume a broad diversity of prey, including aphids, scale, mites, mealybugs, small caterpillars, insect eggs and pupae, white flies, mites, and psyllids. One lady beetle can eat up to 5,000 insects in its lifetime.

When it comes to the lady beetle being eaten, the beetles will secrete an oily, foul-tasting fluid from joints in their legs. They may also play dead. Birds are lady beetles’ main predators, but they also fall victim to frogs, wasps, spiders, and dragonflies.

Where can I get beneficial insects for my garden:

Researchers studying a decline in native ladybugs in the United States and Canada theorize that the population reduction may be due to the introduction of non-native species, climate change, land-use changes, disease, or shifts in the availability of prey. In an effort to track ladybug populations, entomologists at Cornell University created the Lost Ladybug Project, a citizen-based effort to spot, photograph, and report on ladybugs across North America.
