The Asian lady beetle (Harmonia axyridis) belongs to the Coccinellidae family. They originated in East Asia and were introduced to countries of North America and Europe. The species vary in color and are hence commonly referred to as multicolored Asian lady beetles (Harmonia axyridis). They are found in meadows and open fields. They are considered to be beneficial insects as they eat pests that damage crops. Thus, they control the growth of pests in agricultural fields. Their life cycle undergoes four stages, namely eggs, larvae, pupae, and adults. These lady beetles have an average lifespan of 30 to 90 days.

Their breeding season usually occurs at the beginning of spring. They secrete pheromones to attract mates on the breeding ground. Fertilization is internal, and after mating, females lay around 20 to 30 eggs. The eggs are usually yellow in color and hatch after three days. The larvae undergo five developmental stages or instars. They often feed on unhatched eggs. The conservation status of the Asian lady beetle has been marked as Not Evaluated by the Internation Union for Conservation of Nature or IUCN Red List.

Asian lady beetles vary in their coloration from one species to another. Hence they are also called multicolored Asian lady beetles. Mostly they have red or orange bodies with distinct black spots. There can be as many as 19 to 22 black spots present all over the body of lady beetles. Some species have orange spots instead of black. The pronotum present behind the head has a white area with black spots. This black spot forms an M-shaped structure which helps in their identification. These lady beetles are usually darker in color in their native countries, while lighter shades are observed in other areas. They also have square-shaped shoulders. The larvae are usually black, with two distinct orange lines on the dorsal area. They have a body length of 0.2-0.4 in (7.5 to 10.7 mm).

How do they communicate?

Asian lady beetles usually communicate through sensory signals. They secrete various pheromones to communicate with other species. During the breeding season, they release pheromones to attract mates. These chemicals also help to detect other members during hibernation. A particular pheromone, known as Harmonine, is released when they are threatened. They also have good vision along with olfactory sensation, which helps them in hunting for prey.

Yes, Asian lady beetles are considered to be harmful. They often grow uncontrollably on agricultural fields and damage crops. They are known to cause a lot of damage to the grape industry and other native species. They use a mechanism known as reflex bleeding, where they eject a toxic chemical into fruits and other crops. This toxin causes staining and has a bad odor. They are also known to bite humans if provoked. Their bites can be dangerous, forming blisters on the skin and other allergic reactions.

Some individuals are known to be allergic to these insects, and their bites can be dangerous.

Did you know...

Asian lady beetles were named after the farmers who worked in the agricultural fields back in the middle ages. The crops present in the fields were infested by aphids. The farmers sought help through prayers from the Virgin Mary. Following this, the lady beetles appeared and ate the aphids. Thus, the crops were saved from damage. The farmers regarded these insects as 'Our Lady's beetles', and hence, their origin can be traced back to the middle ages.

They hibernate during the winter months for about nine months. The species living in colder regions usually go into a period of hibernation instead of migrating to warmer regions. During this time, they thrive on the fat stored inside their body.

Getting rid of Asian Lady Beetles

Asian lady beetles are introduced to agricultural fields or gardens to control the growth of pests like aphids, but they often cluster in large numbers in houses. Firstly, windows, doors, or other openings should be closed to prevent their entry. They can be removed with vacuum cleaners. Sweeping should be avoided as it can trigger their reflex bleeding mechanism. This can create stains on light-colored surfaces. It is recommended to use gloves while handling them as they can bite. Insecticides can also be sprayed on them. It should be sprayed repeatedly on the places they had previously infested to prevent their re-entry.

Why are Asian Lady Beetles bad?

These insects cause serious damage to crops and form clusters inside the household. They contain a pheromone known as Harmonine, which is released as a form of defense to escape predators. They also carry a chemical called isopropyl methoxy pyrazine. This is released when they are threatened. Lady beetles are also known to bite humans and cause allergic reactions.
