Introduction of ladybug septempunctata

Coccinella septempunctata is a predatory insect of Coccinellidae. Adults can prey on pests such as wheat aphids, locust aphids and ticks. It can greatly reduce the harm of pests to trees, melons and various crops, and is called live pesticide, which is widely distributed in all parts of China.

Feeding characteristics of ladybug septempunctata

The chin of ladybird must be its main sense of touch and smell. Ladybug septempunctata often crawls and searches on the host plants of aphids. When the lower jaw touches the aphid, it can quickly bite the aphid with the upper jaw and swallow it.

If you don't touch your chin, even if the aphid is in front of it, it seems that you can't find it. Although both adults and larvae of ladybug septempunctata feed on aphids, their feeding patterns are different due to different insect states, different mouthparts and structures.

When adults feed, they usually bite aphids and swallow their bodies and appendages completely after simple chewing of their mouthparts. Older larvae basically eat like adults. However, early larvae often bite a hole in the aphid to suck juice because of their small mouthparts and poor swallowing ability, and finally leave the aphid shell.
