The growth environment of bees

The geographical distribution of bees depends on the distribution of nectar plants. It is distributed all over the world and has many tropical and subtropical species. The distribution of different subfamilies or genera has certain limitations For example, bumblebees in the bee family are mainly distributed in the north temperate zone and can extend to the Arctic, but there is no record of distribution in the tropics. Short-tongued bees are distributed in Australia; Trichogramma subgenus of Trichogramma of Meliaceae is only distributed in central Asia. Aphidae are distributed in tropical areas. Bees are distributed in different landscapes, and most of them live in grasslands, forests, valleys, mountains and deserts. Each landscape belt has a representative genus or species. For example, the ground bumblebee is a forest grassland species, the ground bumblebee is a typical grassland genus, and the quasi-bees are mostly grassland species.

Definition of bee: bee/bee belongs to Hymenoptera and Apidae. Body length is 8-20 mm, tan or dark brown, with thick hair. The head is almost as wide as the chest, the tentacles are knee-shaped, the compound eyes are oval and hairy, chewing in the mouth and carrying powder on the hind feet. Two pairs of membrane wings; The front wing is big, the rear wing is small, and the front and rear wings are connected by wing hooks. The abdomen is nearly oval, with less body hair than the chest and thorns at the end of the abdomen. Life goes through four stages: egg, larva, pupa and adult.

Feeding: bees feed on plant pollen and nectar. Eating habits can be divided into three categories.

1, eat more. That is, pollen and nectar. Ruyi bees and Chinese bees feed on plants of different families or flowers of a certain color (not limited to plant species).

2, oligopoly. That is to eat the flowers of related families and genera, such as alfalfa quasi-bees.

3. partial eclipse. In other words, it only feeds on certain plants or related species, such as cornflower bees. The flowers interviewed by various bees are closely related to the length of mouthparts: for example, species with short mouthparts such as Labiatae, Aphidae and Aphidae interview the open flowers of Rosaceae, Cruciferae, Umbelliferae and Ranunculaceae; However, due to the long mouthparts, sawflies, honeybees and other species use deep flower tubes to interview flowers, such as Leguminosae and Labiatae.
