What Do Japanese Ladybugs Eat In The Winter?

Japanese ladybugs (Harmonia axyridis) are one of the most common species found around the world.

In the winter months, these ladybugs will enter a state of hibernation, meaning they are not actively feeding.

When the temperatures begin to warm up in the spring, the ladybugs will wake up and start looking for food.

Ladybugs feed on a variety of insects and pests, such as aphids, mites, and other small insects, consuming hundreds of them per day.

During the summer, ladybugs have many food sources available, like flowers, fruit, and nectar, to ensure they stay healthy.

However, in the winter, food sources can become scarce.

Ladybugs will search for any food they can find, such as huddling together for warmth, or seeking out hibernating insects.

Additionally, they feed on the honeydew produced by aphids to stay nourished during the winter.

To summarize, Japanese ladybugs do not feed actively in the winter, but look for food sources, such as huddling together for warmth or honeydew from aphids.

Do Asian Lady Beetles Eat Plants?

Asian Lady Beetles (Harmonia axyridis) are beneficial to plants because they feed on aphids, which are a common pest of many plants.

However, they can also cause damage to the plants if they feed in large numbers.

Lady beetles usually feed on the surface of the leaves, using their strong mandibles to break through the tough surface and sucking the sap out of the plant.
