Ladybirds are known by a variety of names: ladybug, ladybird beetles, lady beetles, God's cow, ladyclock, lady cow, and lady fly. Entomologists often use the terms ladybird beetles or lady beetles as they are a type of beetle and are not actually a true bug (from the taxonomic order Hemiptera).
Ladybirds are lovely critters to have in your garden (most species anyway). They are attractive and children in particular enjoy finding them around the garden. They are also very beneficial for any garden as they feed on aphids and scale insects. Some even feed on fungi!
You can attract ladybirds to your garden by companion planting with coriander, tansy and sunflowers. Ladybirds are particularly susceptible to pesticides.
