How to Get Rid of Lady Bugs
The Asian lady beetle, also known as Harmonia axyridis, is a type of lady beetle that is native to Asia but has been introduced to many parts of the world, including North America. Here’s some information about its appearance, habitat, and reproduction:
Appearance: The Asian lady beetle is similar in appearance to the native ladybug, with a round, dome-shaped body and distinct spots on its wings. However, it can be distinguished by its coloration, which can range from yellow orange to dark red, and the presence of a distinctive “M” or “W” shape on its head. They are approximately 6-8 mm in length.
Habitat: The Asian lady beetle is commonly found in gardens, fields, and other areas with plants that they feed on. They are attracted to aphids and other small insects and can be beneficial as a natural pest control. However, they can also become a nuisance when they enter homes and buildings in large numbers to overwinter.
Reproduction: Female Asian lady beetles lay their eggs on plants, and the larvae hatch and feed on aphids and other small insects. The pupal stage lasts for about a week before the adult beetle emerges. The entire life cycle can take anywhere from 3-4 weeks.
Destructiveness: The Asian lady beetle is not generally considered destructive and can even be beneficial as a natural predator of aphids and other small insects. However, they can become a nuisance when they enter homes and buildings in large numbers in the fall to overwinter. They are known to release a foul-smelling chemical when threatened or disturbed, which can be unpleasant for humans.
In conclusion, the Asian lady beetle is a common type of lady beetle that can be found in gardens and fields. While they are not generally considered destructive, they can become a nuisance when they enter homes and buildings in large numbers. They are known for their distinctive coloration and the “M” or “W” shape on their head.
