doodlebug

Doodlebug is a term used to describe a type of insect that is part of the family Coccinellidae, commonly known as ladybugs. The term "doodlebug" is often used in North America to refer to the seven-spotted ladybug, Adalia septempunctata, which is native to the region. The name "doodlebug" is believed to have originated from the sound made by the insect when it is disturbed, which is described as a "doodle" or "doodle-doodle" sound.

Doodlebugs are known for their distinctive appearance, with a round, convex body and a pattern of black spots on a red or orange background. They are beneficial insects as they feed on a variety of pests, including aphids, mites, and other soft-bodied insects. This makes them important in integrated pest management strategies for agriculture and horticulture.

The seven-spotted ladybug is one of the most common and well-known species of doodlebug. It is found in a wide range of habitats, including gardens, forests, and agricultural fields. Other species of doodlebugs include the two-spotted ladybug, Harmonia axyridis, which is also known as the Asian lady beetle and has become invasive in some regions.

Doodlebugs play a crucial role in ecosystems by controlling pest populations and contributing to the decomposition of organic matter. Their presence is often seen as a sign of a healthy environment. However, some species of doodlebugs, such as the Asian lady beetle, can become invasive and cause harm to native ecosystems by outcompeting native species for resources.
