1. How to distinguish between male and female earthworms?

Differentiate according to the body shape of the turtle

Female turtle body shape:

The adult body of the Chinese earthworm is about 3.4 cm long and 2 cm wide. The body is oval, gray-brown, flat above and below, and the chest and abdomen are brown-red.

The head is small and hidden in the prothorax, with a pair of antennae, a pair of well-developed compound eyes, a chewing mouthpart, horizontal segments on the back arranged in a shingle-like manner, and three pairs of well-developed feet on the chest.

Male turtle body shape:

The male earthworm is 2.8 cm long, 1.5 cm wide, light brown, and light in body. Its head is slightly smaller than that of the female, with 3 pairs of legs and 2 pairs of wings, which are relatively well developed.

The forewings are leathery, the hindwings are membranous and translucent, folded on the back, and have the ability to fly short distances, up to 5-6 meters from top to bottom, and have a pair of tail whiskers.

Additional information:

The female is shiny black, while the male is light brown and dull. It has an oval body shape, about 35 mm long, a small head hidden on the ventral side of the prothorax, and a pair of antennae about 20 mm long on its head. The compound eyes are large, surrounding the outer side of the antennae. The female is wingless, while the male has wings. It often moves in the soil at the base of residential walls.

The dried female insects are medicinal materials that can treat injuries and trauma. Some studies have found that they can also treat cancer, so they are beginning to be artificially bred in large quantities.

The one with a flat bottom and a short tail is a female; the one with a concave tail and a long tail is a male.

Female turtle body shape:

The adult female earthworm is about 3.4 cm long and 2 cm wide. The body is oval, gray-brown, flat above and below, with a brown-red chest and abdomen, a small head hidden in the prothorax, a pair of antennae, a pair of well-developed compound eyes, a chewing mouthpart, horizontal sections on the back arranged in a shingle-like manner, and three pairs of well-developed legs on the chest.

Male turtle body shape:

The male earthworm is 2.8 cm long and 1.5 cm wide, light brown, light in body, with a slightly smaller head than the female, 3 pairs of legs, 2 pairs of wings, which are relatively well developed. The forewings are leathery, and the hindwings are membranous and translucent, folded on the back. It has the ability to fly short distances, and can fly up to 5-6 meters from top to bottom. It has a pair of cerci.

The one with a flat bottom plate is female, and the one with a concave bottom plate is male.

The one with a short tail is female, and the one with a long tail is male.

Did you know that when turtles mate, the male is on top and the female is on the bottom? To prevent the male from slipping off the female's shell during mating, the male's plastron is slightly concave, just enough to fit the protruding back shell of the female. However, the female does not need this structure, so the plastron is flat. Now you can understand that you can quickly tell the difference between male and female by turning the turtle over and touching the plastron with your finger.

The patterns on the belly of the male turtle are sparse, while the patterns on the belly of the female turtle are dense.

Female turtle: The carapace is short and wide, the plastron is flat with no depression in the center, the tail is thin and short, the base of the tail is thin, the cloaca is close to the posterior edge of the plastron, and the notch formed by the two anal shields of the plastron is shallow and the angle of the notch is large.

Male turtle: The carapace is long and narrow, the center of the plastron is slightly sunken inward, the tail is thick and long, the base of the tail is thick, the cloaca is far from the posterior edge of the plastron, the notch formed by the two anal shields of the plastron is deep, and the angle of the notch is small.

Note that male turtles turn black as they mature, while female turtles remain their original tan color.

Because the reproductive organs of turtles are all wrapped inside their bodies and they look the same, it is difficult to distinguish their gender without certain skills. But as long as you understand the mating posture of turtles, you can tell them apart. When turtles mate, they adopt the posture of male on top and female on bottom. In order to avoid slipping off the female turtle's shell during mating, the male turtle's plastron is slightly concave, which can just fit the protruding back shell of the female turtle; but the female turtle does not need this structure, so the plastron is flat. Just turn the turtle over and touch the width of the plastron with your fingers, and you can quickly tell the gender. Follow-up question: I'm asking a country bumpkin! ! ! What are you talking about turtles? Answer: Although they have different names, the methods of distinguishing them are similar.
