Adalia bipunctata

The Latvian national insect is the two-spot ladybird (Adalia bipunctata). The two-spot ladybird is familiar as a useful insect that protects plants from parasites. Although rather slow by nature, it can defend itself well. Due to its appearance and behaviour it is widely known and liked throughout Latvia. The insect's Latvian name - marite - is a synonym for the ancient Latvian goddess Mara, who embodies the power of the earth. The two-spot ladybird was designated the national insect of Latvia by the Entomological Society of Latvia.

There are about 5,000 different species of ladybugs in the world. These much loved critters are also known as lady beetles or ladybird beetles. They come in many different colors and patterns, but the most familiar in North America is the seven-spotted ladybug, with its shiny, red-and-black body. In many cultures, ladybugs are considered good luck.

Most people like ladybugs because they are pretty, graceful, and harmless to humans. But farmers love them because they eat aphids and other plant-eating pests. One ladybug can eat up to 5,000 insects in its lifetime! Most ladybugs have oval, dome-shaped bodies with six short legs. Depending on the species, they can have spots, stripes, or no markings at all. Seven-spotted ladybugs are red or orange with three spots on each side and one in the middle. They have a black head with white patches on either side.

Ladybugs are colorful for a reason. Their markings tell predators: "Eat something else! I taste terrible." When threatened, the bugs will secrete an oily, foul-tasting fluid from joints in their legs. They may also play dead. Birds are ladybugs' main predators, but they also fall victim to frogs, wasps, spiders, and dragonflies. Ladybugs lay their eggs in clusters or rows on the underside of a leaf, usually where aphids have gathered. Larvae, which vary in shape and color based on species, emerge in a few days. Seven-spotted ladybug larvae are long, black, and spiky-looking with orange or yellow spots. Some say they look like tiny alligators. Larvae grow quickly and shed their skin several times. When they reach full size, they attach to a leaf by their tail, and a pupa is formed. Within a week or two, the pupa becomes an adult ladybug.
