Delaware State Bug: Ladybug

Delaware State Bug - Ladybug

The ladybeetle, more commonly called ladybug or ladybird beetle, is the popular name given the Coccinella 7. This beetle was dedicated to the Virgin Mary and called "Beetle of Our Lady." They are around four-tenths of an inch long, brightly colored, round, with the popular ladybug having four black spots on each wing. Ladybugs are sold to farmers to control insect pests because they are important aphid predators. The life cycle is about four weeks as the ladybug larvae passes through four growth stages feeding on insects and insect eggs. The reddish-orange ladybug has distinctive black spots on each wing cover.

It helps farmers by controlling insect pests, especially aphids. In folk medicine, ladybugs were believed to cure various diseases such as colic and measles. In folk medicine ladybug beetles were used to cure various diseases including colic and the measles.

Some Facts About Ladybugs:

  1. Ladybugs are the most popular and widely used beneficial insects for commercial and home use. Ladybugs are capable of consuming up to 50 to 60 aphids per day but will also eat a variety of other insects and larvae including scales, mealy bugs, leaf hoppers, mites, and various types of soft-bodied insects, and are one of the most active predators, searching from dawn to dusk for food.
  2. Ladybugs will consume over 5,000 aphids each in their lifetime. Pollen and nectar are necessary for maturation of newly emerged ladybug adults, particularly before a winter hibernation season. Adults can survive on pollen and nectar for limited periods, but a supply of aphids or other prey is necessary for egg production.
  3. Ladybugs become active at about 59 degrees Fahrenheit.
  4. Ladybugs are cold-blooded and hibernate in cold weather.
  5. There are nearly 5,000 different kinds of ladybugs worldwide - 400 of which live in North America.
  6. A ladybug's top flying speed is about fifteen miles per hour.
  7. Ladybugs lay their eggs where aphids are present. Both lady bugs and their larvae eat aphids. The eggs of ladybugs are not visible to the naked eye.
  8. A female ladybug will lay more than 1000 eggs in her lifetime.
  9. Ladybugs are a type of beetle. All species of ladybugs have short legs. This separates them from other beetles.
  10. Ladybugs chew from side to side and not up and down like people do.
  11. The Ladybug is the Official State Insect of six states; New York, North Dakota, Ohio, Massachusetts, New Hampshire and Tennessee. The Lady Bug is the Official State "Bug" of Delaware.
  12. A ladybug excretes a yellowish liquid when it is threatened. The liquid has a terrible smell to its predators.
