Activities at night and at night, feeding on insects. Spiders secrete a viscous liquid, which is secreted into filaments through the spinneret protruding from the foot. And then woven into a net. Spiders catch trapped insects with pincers that grow at the front end of their bodies, secrete a poisonous juice from pincers, paralyze insects, and then spit digestive juice into insects to dissolve protein, dilute internal organs, and turn insects into juice food and suck it into digestive tract. Because the worm's shell is not protein, it can't be dissolved by digestive juice, so it stays intact on the spider's web, and sometimes the prey it catches will be eaten alive immediately. Spiders are warm-blooded animals. Generally, you can't eat or move below 2℃ and enter hibernation. After the females and males mature and mate, females lay eggs every night from the end of August to 10. After the fertilized egg is produced, it is wrapped with spider silk to form an egg bag. Each egg bag contains 50 ~ 1000 yellow-brown spherical fertilized eggs, and the female spider carries the egg bag with her for protection. Different kinds of spiders spawn at different times. They hatched on the warm ground that year and were stored in oocysts the next day. When the temperature rises in the next spring, the eggs will become young spiders. The young spider just hatched from the egg crawls on the back of the mother spider and lives independently after 3-5 days.
