Ladybugs are scientifically known as Coccinellidae, and are distinctive by their small black spots on their back along with orange, red and yellow base colours. However, many ladybugs' colour can vary depending on many factors. An example of this is the Vibidia Duodecimguttata species, which has 12 white spots on a brown base colour. Additionally, there are over 6,000 species of ladybug already known.
Although Coccinellids are known as ladybugs in the USA, other parts of the world such as Britain refer to them as ladybirds as do some other English speaking countries. Experts refer to them as beetles, as they are not technically classed as true bugs.
Ladybugs are recognised as being one of the most useful insects on the planet; as they keep aphids and other agricultural pests at bay. Ladybirds are known to make use of aphids by laying their eggs directly on their colonies, ensuring their offspring have a food source ready. However, there is one known species which is herbivorous, the Mexican bean beetle, found in tropical climates that contribute to the agricultural pest problem; although only minor.
The scientific name for ladybug, Coccinellids, is taken from the Latin word coccineus which means scarlet (red).
