ALBs are able to thrive in agricultural fields, woodlands, and even urban areas.
This is because they have an extremely diverse range of food sources.
They can feed on a variety of pests, including aphids, caterpillars, and scale insects.
In addition, they can feed on pollen, nectar, and other plant matter.
This adaptation has allowed the ALBs to expand their range and become an invasive species in many parts of the United States.
However, it is not only their dietary needs that have allowed ALBs to become so successful.
They have also adapted to different climates and temperatures, allowing them to survive in both cold and warm climates.
Additionally, they have adapted to different lighting conditions, allowing them to be active both during the day and at night.
Finally, ALBs are also highly adaptable when it comes to their living environment.
They can live in a variety of places, from agricultural fields to urban areas and even inside homes.
This is why ALBs have become a nuisance in many homes, where they congregate in large numbers.
In conclusion, Asian Lady Beetles are highly adaptable insects, capable of thriving in a variety of habitats.
This has allowed them to spread throughout the United States and beyond, becoming an invasive species in many parts of the country.
They can feed on a wide range of food sources, survive in different climates and temperatures, and live in a variety of places.
As such, understanding the adaptability of ALBs is key to understanding their success as an invasive species.
