Studies show that invasive species are one of the main drivers of biodiversity loss and declination of different species. The Harlequin Ladybug has mostly impacted the 2-spotted Ladybug by taking away shared resource, aphids. Aphids are types of plant lice and the most known are the green, black, and white flies. They are herbivores, thus they feed on plants obviously.
The effects the Harlequins can bring are by depleting a resource (aphids) that eats certain plants to keep the ecosystem in balance. The Harlequin's fierce competition is also a very strong factor leading to high reproduction rates. These imbalances cause researchers to investigate any decline in any species by this invasion and hope no devastation will occur.
