What are the three differences between scarab beetles and ladybugs

The first time I learned about scarab beetles was because a host on "Da Feng Che" had the same name. Later I learned that scarab beetles actually belong to the class Insecta. Many people say scarab beetles are just seven-spot ladybugs? Actually they are not, they are two kinds of insects in the class Insecta, so, what are the differences between scarab beetles and ladybugs?

1. Different social behavior

The scarab beetle is recognized at home and abroad as a soil-dwelling pest that is difficult to control. It mainly bites and feeds on forest trees, fruit trees, crops, etc. It damages pear, peach, plum, grape, apple, citrus and many other forest trees

The seven-spot ladybug is a predatory insect and a beneficial insect. It can prey on many pests, and many people call it a “living pesticide”. Predatory natural enemy, host insects: cotton aphid, wheat aphid, bean aphid, cabbage aphid, corn aphid, sorghum aphid. Host crops damaged by the seven-spot ladybug: cotton, wheat, cowpea, Chinese cabbage, corn, sorghum

2. Differences in outward appearance

The adult scarab beetle is mostly oval or elliptical in body shape, with gill-like antennae made up of 9 to 11 segments, and each segment can open and close freely. The seven-spot ladybug is likewise oval, shaped like a water ladle. It has 7 black spots on its two sides, which is its very obvious distinguishing feature, and its belly and legs are black.

3. Differences in living habits

Scarab beetle larvae mostly feed at depths of more than 10 cm, usually crawling up from deep layers to the surface in the early morning and at dusk in summer, biting and feeding on the stems near the ground, main roots and lateral roots of bamboo and willow. Adults vary in feeding habits; some feed on plant roots, stems and leaves, some feed on decaying organic matter, and some feed on feces. The larvae are mainly in the soil and feed mainly on organic matter in the soil.

This species of seven-spot ladybug is very widely distributed, but the seven-spot ladybug is still a symbol of organic agriculture! It rarely gathers in groups. However, adults looking for food are often seen in aphid clusters outdoors. It overwinters as an adult and emerges from dormancy in April of the following year. Both adults and larvae feed on many kinds of aphids, jumping plant lice, etc. It is a beneficial insect and should be protected.

The scarab beetle belongs to the class Insecta and is also a pest. Dialect “gv gn ”. It bites and feeds on forest trees, fruit trees, crops, etc. There are very many varieties.
