Ladybugs are small insects, that are commonly yellow, orange, or scarlet with small black spots on their wing covers, with black legs, head and antennae. A very large number of species are mostly or entirely black, gray, or brown, however, and may be difficult for non-entomologists to recognize as coccinellids (and, conversely, there are many small beetles that are easily mistaken as such, like tortoise beetles).
They are considered useful insects as many species feed on aphids or scale insects, which are pests in gardens, agricultural fields, orchards, and similar places. Because they are useful, colourful, and harmless to humans, coccinellids are typically considered appealing even by people who hate most insects, though a few species are pests in North America and Europe. Some people consider seeing them or having them land on one’s body to be a sign of good luck to come, and that killing them means bad luck.
