Want to know what are the identification methods of north and south species of scarab?

Here are some ways to identify the northern and southern stone turtles:

First, look at the color of the shell.

The shell color of southern species turtles is generally yellow or black or bronze, while that of northern species turtles is generally cyan or green or yellow-green. ?

Second, look at the color.

The head color of southern species of stone turtles is generally gray-black, yellow or bronze, and some southern species of stone turtles may also have some black broken spots, commonly known as "plum blossom spots" (but not all southern species of stone turtles have "plum blossom spots"). The head color of the northern stone turtle is cyan or green, and there are no black spots on the head.

Third, look at the side shield.

Generally, southern species of turtles can see the edge shield in the middle of the carapace from top to bottom, while northern species of turtles can't see the edge shield in the middle of the carapace from top to bottom.

Fourth, look at the black spots.

The black spots on the carapace of southern species are generally large and clear, while the black spots on the carapace of northern species are generally small (even absent) and fuzzy.

Fifth, look at the eyeliner

There is usually a black line (long or short, thick or light) in the center of the eyeball of the southern species of stone turtles, while there is generally no black line in the center of the eyeball of the northern species of stone turtles.

The above "five views" are some simple and basic standards for analyzing and identifying the northern and southern species of stone turtles, but these standards can not be used simply and unilaterally, and should be combined to improve the identification quality. For example, for the use of the "look at the eyeliner" standard, we should not only determine whether the eyeliner of the tortoise is long or short, thick or light, but also analyze it in combination with other "four look" standards. If the eyeliner of a turtle is not obvious enough, but the shell color is yellow or black, the head color is grayish black or yellow or bronze, and the side shield and black spots basically meet the standards of southern turtles, it can be determined that this turtle is a southern turtle rather than a northern turtle. If you do it again, a stone turtle's head is a little blue (such as yellow with blue), and the eyeliner is not obvious enough, but the shell color, side shield and black spots are not the characteristics of the northern stone turtle mentioned above, it can be determined that this stone turtle is not a northern stone turtle, but a southern stone turtle.
