The seven-star ladybug has to go through four different stages of development in its life: egg, larva, pupae and adult, and the development period of each insect state is mainly affected by food and temperature. Ladybird is a migratory insect, and the foraging behavior of adults and larvae belongs to the transition between wide-area search and regional centralized search behavior. The ladybug feeds mainly on aphids, sometimes small soil particles, fungal spores, and some small insects, and often pollen from plants in autumn.
It is widely distributed in Africa, Europe, and Asia.
The lower jaw whiskers of the seven-star ladybug are its main organs of touch and smell. The seven-star ladybug often crawls and searches on the host plant of the aphid, and when the lower jaw whiskers touch the aphid, it can quickly bite with the upper jaw and swallow the aphid. If the lower jaw whiskers are not touched, it seems impossible to detect the aphid, even if it is right in front of its eyes.
Although both adults and larvae feed on aphids, the feeding methods are different due to different insect states and different mouthparts structure. When adults feed, they usually bite the aphid, and after simple chewing with their mouthparts, they swallow the aphid's body and appendages completely. Older larvae feed in much the same way as adults.
However, due to their small mouthparts and poor swallowing ability, the first instar larvae often bite a hole in the aphid's body to suck the juice, and finally leave the aphid body shell. An adult of the seven-star ladybug eats an average of 100-120 cotton aphids, 147 vegetable aphids, and 59 apricot aphids a day. The amount of aphids eaten by larvae varies according to the size of the instar, with less snacks in the instar and more in the instar period.
Ladybugs have a habit of eating eggs and preying on each other. In the case of insufficient food, the adult ladybug can easily eat the egg masses that have been laid. Even when there are plenty of aphids, they like to eat the eggs; The larvae often prey on each other.
Individuals who hatch early from the same egg mass often eat eggs that have not yet hatched. Older larvae often eat younger larvae. Pupae are also commonly eaten by adults and older larvae.
