Are There Green Ladybugs?
There are no true green ladybugs. However, certain species of spotted cucumber beetles resemble ladybugs, and there are vivid yellow ladybug beetles that may appear green under certain lighting conditions.
Ladybugs, or ladybirds, are small beetles belonging to the family Coccinellidae. These beetles are often vivid shades of red, orange or yellow and most have two or more black spots. There are also white ladybugs and ladybugs with orange spots on a black background. The vibrant colors of ladybugs serve as a warning to predators that these beetles have a particularly unpleasant taste. There are, however, no truly green ladybug beetles.
Small, green black-spotted beetles do exist. One such beetle is the spotted cucumber beetle. These colorful beetles belong to the family Chrysomelidae. While many ladybug species are often helpful predators of garden pests, such as aphids, cucumber beetles are themselves pests. Adult beetles damage the leaves of crop plants like cucumbers and soybeans. The larval form, the corn rootworm, burrows into and damages young plant roots. Cucumber beetles are greenish yellow with six black spots on each wing cover. The body is a more distinct oval than most ladybug species and the antennae are more noticeable. Like the cucumber beetle, some ladybug species are actually pests, feeding on plants rather than nuisance insects.
