Ladybug
Ladybug is the common name for beetles in the family Coccinellidae, also called ladybird beetles or lady beetles.
Ladybugs are small beetles from the family Coccinellidae, known for their bright colours and appetite for plant pests. They are widely considered beneficial insects in gardens and agriculture.
What it is
Ladybugs are beetles, not true bugs, and belong to the family Coccinellidae. They have rounded, often brightly coloured bodies and short legs. The common name dates back to medieval Europe, where they were called 'beetle of Our Lady' in reference to the Virgin Mary. About 5,000 species are found worldwide, ranging in colour and spot patterns.
Why it matters
Most ladybug species prey on soft-bodied pests like aphids, mites, scale insects, and whiteflies. This makes them valuable allies in Canadian gardens and agriculture, reducing the need for chemical pest control. They are harmless to humans and widely regarded as beneficial insects.
Key details
Ladybugs lay eggs on leaves; larvae develop through a pupal stage before becoming adults. They live about 2–3 years and inhabit gardens, forests, grasslands, and urban areas. Many adults overwinter in sheltered groups. Their size varies, with many species reaching 8–10 mm.

- Many species eat aphids and other plant pests.
- They are harmless and beneficial in gardens.
- Over 5,000 species exist worldwide.
