![]() Therefore, the order of the males is not as important as the amount of sperm that each one is capable of providing.ĭuring intercourse, females usually make sounds or stridulations. This is because females can copulate with multiple males, storing everyone's sperm in their reproductive system. The longer the sexual intercourse lasts, the more chanced the male will have to be a father. The introduction of the copulatory organ is repeated several times. This information is indicative, since the posture adopted during copulation varies in each species. He introduces his sperm with his copulatory organ, which is also found in the pedipalps. Then he lifts her onto him and can access her genital pore. Once the female decides that a male is suitable, he grabs her by the chelicerae using forceps on the pedipalps. Intercourse is the most important process in understanding how spiders reproduce. These sounds are usually not audible to humans. Some males bump their limbs against each other or against the ground, emitting a type of “song”. Lastly, communication through sounds or stridulations has been documented in many spiders. If the female realises that it's a trick they can decide not to mate. Sometimes they try to trick them by offering females an inedible item. For example, males of Pisaura mirabilis wrap insects in silk and offer them to females. These males raise their third pair of legs and vibrate their bodies while displaying their colorful drawings.Īnother strategy to win over females is to give them a bridal gift. This is the case of the “peacock spiders” ( Maratus spp.). In some species, the male performs a courtship dance to attract the female's attention. For this, they usually perform a series of wedding rituals. In active predators, however, females and males are similar in size, although differences in color may appear.īefore copulation, both congeners must be sure that they are the ideal partner. For spiders, females are often much larger than males. Sexual dimorphism appears in many spider species. The female tends to take care of the eggs and, sometimes, also of the young. In most of the species we can also observe parental care. After copulation, females lay tens or even thousands of eggs, depending on the species and weather conditions. This couple is only momentary, since both males and females mate with several individuals in the same reproductive season. ![]() For this reason, there are males and females that must copulate for new spiders to be born.īefore that, they must choose their sexual partner through courtship. We already know these interesting animals very well, but how do spiders reproduce? The reproduction of spiders is sexual, in other words, a female and a male must unite and form an embryo. An exception is the Uloboridae family that lacks venom glands. In this way, they are converted into liquids and subsequently sucked. In addition, the poison may contain substances that dissolve the tissues of prey. Poison: after trapping their prey, they inoculate toxic substances to paralyze or kill it.To get their food, they have very diverse hunting strategies: nets, traps, camouflage, etc. Predators: these arachnids are quite voracious predators.There is only one herbivorous species known to us (Bagheera kiplingi ). ![]() Many of them supplement their diet with nectar or other plant food sources. Carnivorous: spiders feed by sucking the internal fluids of other arthropods, especially insects.They use them to inoculate venom into their prey. Chelicerae: is the mouth part, often referred to as “jaws”.It is a very important feature to understand how spiders reproduce. They are usually larger in males, who use them during courtship and also as a copulatory device. Pedipalps: are appendages similar to the legs, although they are raised and in front of the body.Through them they emit silk threads that they use for various purposes, such as building spider webs, transporting or protecting their spawn. Rows: spiders present some structures known as rows on their abdomen.It is followed by the second segment, the abdomen. The first part, where their "head" is located, is known as a cephalothorax. Segmentation: Their body is divided into two parts. ![]() This is a characteristic that differentiates them from the rest of arthropods.
