What plants do beetles eat and what food do beetles eat?

There are many classifications of beetles, including saprophyrcus, dung-eating, corpse-eating, herbivorous, predatory, and parasitic, and different species of beetles have very different feeding habits. Some beetles eat crop leaves, while others eat animal carcasses and feces. Herbivorous beetles are mostly pests, and predatory beetles such as seven-star ladybugs are mostly beneficial insects.

Crop leaves and animal carcasses are what beetles like to eat, but there are many species of beetles, and different species of beetles have very different eating habits.

The feeding habits of beetles can be divided into saprophagous, fecal-eating, corpse-eating, herbivorous, predatory and parasitic, etc., some beetles need to parasitize in insects, mammals or bird nests, and some beetles mainly live in animal feces, corpses, litter or soil.

The vast majority of herbivorous species of beetles are important pests of agriculture and forestry, and many of the predatory species of beetles are beneficial to humans, such as the seven-star ladybug in the ladybugidae family.

Carnivorous beetles like ladybugs feed mainly on small insects and some pests, such as wheat aphids, cotton aphids, locust aphids, peach aphids, scale insects, ticks, etc.

The feeding habits of adults and larvae are complex, including saprophagous (Yanjia) and dung-eating (dung beetles.

Cadaverous (burial armor), herbivorous (various leaf beetles, flower beetles), predatory (foot beetles.

tiger carapace) and parasitism, etc. There are many herbivorous species that are important pests of agricultural and forestry crops, and some live in the soil to damage seeds, roots and seedlings, such as the larvae of the kowtow family (needleworm) and the larvae of the family Turtle beetle (grub).

Wait. Some of them are bored or bored to damage forest trees, fruit trees and cash crops such as sugarcane.

Such as larvae of the family Longhornidae and Giddingaceae, etc.; Some feed on leaves, such as leaf beetles and adults of many beetles; Some are important stored grain pests, such as most species of the Legumaceae family, which exclusively eat legumes.

Mongolian gray weevil, two-leaf beetle, leek leaf beetle.

1. Mongolian gray weevil: it is Coleoptera, weevilaceae. It is distributed in Northeast China, North China, Jiangsu, Inner Mongolia, Northwest China and other places. It mainly harms cotton, hemp, millet, cabbage, sugar beet, melon, corn, peanut, soybean, sunflower, sorghum, tobacco, fruit tree seedlings, etc.

2. Two leaf beetles: insect name, for Coleoptera, leaf beetle. It is distributed in various soybean producing areas in China, Japan, North Korea, Russia, southeastern Siberia, etc. The body is small, oval to oblong-ovate, yellowish-brown.

3. Leek leaf beetle: belongs to Coleoptera, leaf beetle. It is distributed in Liaoning, Inner Mongolia, Gansu, Xinjiang, Hebei, Shanxi, Shandong, Sichuan and other provinces. Host leeks, onions, garlic, cabbage. Adults eat leaves, and larvae eat roots and bulbs in the soil.

Beetles are the oldest type of insects, and they flourished in the Upper Jurassic or Lower White Quay periods. At that time, higher plants had not yet appeared, nor did hymenoptera and lepidopteran insects, and beetles were the earliest pollinators in geological history.

The primitive type of beetle has a positive neckline, which is suitable for pollinating some plants with larger, flattened flowers (butterfly or bowl-shaped) than primitive types, and they have a strong smell to attract beetles.

There are many species of common beetles, the largest of which is Coleoptera. The eating habits of each of these families vary greatly.

1. The common longhorn beetle eats leaves or tender bark, 2. Goldenrod insects eat leaves, 3. Dung beetles (dung shells) eat putrefactive substances in human and animal feces, and 4. Bujia feeds on earthworms and snails.

5. Ladybugs feed on aphids (some species feed on sucking plant juice and are pests) 6. There is also an aquatic beetle, which feeds on plankton as its main food.

Therefore, the beetle species are different, and the feeding habits are also different.

Aphids, sprouts of fruit trees, and young shoots of trees, etc.

Vegetables from the field are generally fine.

Beetles eat a wide range of food, but need to be treated differently according to its species, in general, divided into corpse carrion-eating, feeding, parasitic, fecal-eating, herbivorous predators, these are widespread and very common.

The carrion-eating habit is to eat some rotten food, and the feeding habit is mainly to eat the leaves of some plants, which is very common for this type of beetle, like some ladybugs. Parasitic beetles, on the other hand, live on the bodies of certain animals and feed on their blood. Like dung-eating, it feeds on animal feces, such as dung shells.

The herbivorous predatory beetle will live on predation, such as the seven-star ladybug, which belongs to the category of beetles, but it is beneficial to crops and also specializes in preying on pests.
