Bees

Bees are insects closely related to wasps and ants, that produce pollen used in making honey.  
Bees are in the superfamily Apoidea.
There are 20, 000 species of bees, in 7 different families, though many bees are undiscovered. They can be found everywhere except polar regions and oceans, everywhere where there is flowering plants (plants with flowers). Some species such as bumblebees, honeybees, and stingless bees live in colonies. Bees have adapted to feed on nectar and pollen using a long tongue. The pollen produced by bees is used as food for larvae. 

BEETLES

 
Beetles are a group of insects from the family Coleoptera. About 25% of earth's life is beetles, and only about 40% of the beetles on earth are discovered. There are 400,000 known species, and estimated about 1,000,000 beetles in total, leaving about 60% more to discover. The distribution of beetles is basically worldwide, besides polar regions and oceans, but everywhere else you can find beetles. They often feed on plants, fungi, and dead humus (debris on forest floor), and some feed on other invertebrates. some even feed on birds and mammals. Some species of beetles are pests, feeding off crops and destroying forests. But others, such as ladybirds or ladybugs (family Coccinellidae), feed on beetles and other invertebrates that destroy crops and forests, helping control the number of dead trees or destroyed crops.
