Spiders are terrestrial ecosystems.
The most abundant predatory natural enemies play an important role in maintaining the stability of agricultural and forestry ecosystems. The body is 1 90 mm long, and the body is divided into two parts: cephalothorax (anterior) and abdominal (posterior), and the cephalothorax is covered with dorsal armor and chest plate.
Feeding habits. Spiders feed on insects, other spiders, myriapods, and some spiders also feed on small animals. Jumping spiders.

Spider Habits:Because spiders are highly sensitive to changes in environmental factors including habitat structure, habitat type, wind, humidity and temperature, they can be used as indicator groups to monitor changes in habitat and biodiversity.
The changes in species composition and abundance have become important indicators for environmental monitoring, which can well reflect the process of environmental change and its impact on biodiversity.

Yes, spiders that can "fly" are called wind spiders.
Although the wind spider is common, when the wind rises, it climbs to a high place, cocks its tail upwards, and spews out a few strands of silk that become entangled and wound into a parachute.

There are more than 35,000 species of spiders in the world, and the common species are round spiders, bulbous spiders, Lashi spiders, fly tigers, wall lines, funnel web spiders, etc. The largest spider in the world is the Latin American birdcatcher spider, which weaves a sturdy web that can hold small birds weighing up to 300 grams.
