What food does the lady beetle eat?

Lady beetle is a herbivorous insect. Adults and larvae peel off the mesophyll on the back of the leaf, leaving only the epidermis, forming many irregular and translucent fine concave lines, shaped like the bottom of a basket, and can also eat the leaves into holes or with only veins left. Brown, the whole plant died. Eggplant fruit and melon strips are often broken where they are eaten, and the tissue becomes rigid, rough, and bitter, making them unbearable to eat.

Are ladybugs beneficial or pests?

Ladybugs are both pests and beneficial. There are many kinds of ladybugs, which can be divided into carnivorous ladybugs and herbivorous ladybugs in terms of feeding habits. Adult carnivorous ladybugs will prey on any insects with tender flesh, and they like to eat aphids the most, such as the seven-star ladybug. Most species of phytophagous ladybugs feed on Solanaceae, Cucurbitaceae, and Compositae plants, such as Potato Ladybug and Solanum coccinella, which collectively eat the leaves of eggplant and potato and are regarded as pests.
