Small, body length is generally only 1-3 mm. There are 8 ocelli on each side, but some species have no ocelli. The antennae have 4 segments; the legs have no tarsal segments. If the abdomen is composed of 6 segments, it is called Collembola (general springtails); if the 6 abdominal segments heal into a spherical shape, it is called Collembola (round springtails).
There are about 6,000 known species in the world, and there are 193 species in my country. Springtails are found throughout the world, living in soil, among weeds, in humus, under tree bark, and in ant and termite nests. The density of springtails is astonishing. According to reports, 230 million springtails were found in a range of 1 acre of grass from the surface to a depth of 9 inches underground.
