Coccinellidae beetles are commonly called what in North America?

Coccinellidae beetles are commonly called ladybugs in North America.

The family includes the familiar small, rounded beetles often marked with red, orange or yellow and contrasting spots. “Ladybug” is the usual North American term; “ladybird” is more common in Britain and many other regions. Both names refer to the same beetle family, not to a separate insect group. The “lady” traditionally alludes to the Virgin Mary, whose red cloak was associated with these beetles in European folk naming.

Many adult and larval coccinellids eat aphids, scale insects and other plant-sucking pests, which has made them valuable in agriculture and biological control. However, not every species is beneficial: some feed on plants, fungi or other insects, and the multicolored Asian lady beetle can become a household nuisance. Their bright colors often advertise chemical defenses, and threatened beetles may release yellowish, foul-tasting fluid from their leg joints.
