Nowadays, more and more people are keeping alternative pets, many of them are young people. How to distinguish between male and female spiders? The most common way to identify is to observe the skin shed by the spider, compare the spider's growth rate, check the sperm fist, etc.
After the spider usually sheds its skin, turn it over and look at the inside. If there is a small piece between the 4 white spots, it means it is female. On the contrary, if it is very smooth and has only an inconspicuous thin line, it is male. Examination under a microscope will make it clearer and applies to all spiders of all sizes. To accurately identify the female of a spider, you may also want to examine the ratio of legs and teeth. In the 3rd and 4th quarters of the spider's 2nd and 3rd opponents, which are the longest from the end, there will be obvious differences between males and females. The difference in the ratio between the 3rd and 4th segments of a male spider is relatively large, and the 4th segment is obviously much longer and thinner than the 3rd segment, and there is a significant change at the intersection of the 2 segments, just like the joints of bamboo, with straight lines. Straight structure. In female spiders, the ratio difference between these two segments is relatively small, and the junction is smoother and fuller.
In the same situation, the root of the female's teeth is thicker, and the difference between the width of the head and the width of the head is smaller; while the opposite is true for the male. In addition, the spiders have a stripe on their belly, while the female has only one white stripe, and the male has black stripes in the white. In addition, adult male spiders have sperm fists, but female spiders do not.
