Types and names of spiders

Spiders include bird spider, China tarantula, new lady spider, white-fronted cancer spider, furrow scleroderma spider, cave spider, safari spider, web spider, red spider and so on. Bird-catching spiders are brown and oversized, usually about 7 cm long. China tarantula is densely covered with fine black, white and yellow hairs, with brown head, chest and back, and yellow-brown longitudinal spots in the center.

China tarantula is a burrowing tarantula in the northern cotton region of China. Most of them live in plain areas and plain cotton fields in mountainous areas, and dig holes to build houses in large depressions, plots, fields and ditches far away from villages without water.

China tarantula usually goes out for food after sunset, so it can eat a variety of agricultural and forestry pests, so it is also called "earthman" in southwest Shandong. In its caves, the remains of adults such as scarab and Noctuidae can often be dug up.

In the complex natural selection, spiders that can weave a complete network structure survive because they can get enough food, and evolve into different forms because of different environments.
