Asian Lady Beetles
Asian lady beetles, sometimes known in the US as Halloween lady beetles or ladybirds, are often confused for ladybugs. The two are closely related, but Asian lady beetles are typically larger than ladybugs, at about a quarter of an inch long. Their color can vary widely from tan to orange to red, though they are predominantly orange. They have several black spots on their wing covers- 19 spots to be exact- although on some beetles, the spots may be indistinct or missing. Asian beetles eat other insects. They were originally introduced to North America as a form of control for aphids, their favorite food.
Though Asian Lady Beetle adult females are prolific egg layers, their reproduction depends on one key ingredient- prey. Without their prey, Asian lady beetles do not have the protein, and therefore energy, they need to produce eggs. Fortunately, the prey needed to reproduce is not found in your home during the winter. However, fall is a completely different story.
