Tarantulas Mating and Reproduction

Tarantulas mating and reproduction is a fascinating process. The male tarantula will approach the female from behind and begin to tap her abdomen with his legs. If she is receptive, the male will then spin a web around her and wrap her in it. This web helps to protect the male from the female’s sharp fangs during copulation. Once the female is secure, the male will move back around to the front and insert his pedipalps, the modified front legs found on male tarantulas, into the female’s genital opening. The pedipalps then release sperm which is stored in the female’s spermathecae or sperm receptacles.

After mating, the female tarantula will then lay her eggs in a large cocoon which she builds from silk. She will often add leaves or other debris to the cocoon for protection. Once they lay the eggs, the female will guard the cocoon until the spiderlings hatch, which can take anywhere from two weeks to two months depending on the species of tarantula. When the spiderlings hatch, they will climb on their mother’s back and ride around with her until they are big enough to venture out on their own.

Tarantula Mating Behavior

Tarantula mating behavior is a fascinating subject. A tarantula will typically adopt a courtship ritual before mating. This usually involves the male tapping the female with his front legs in an effort to attract her attention and entice her to mate. After successful contact, the male will then move around the female and position himself to attempt to insert his pedipalps into her genital opening. 

Pre-Mating Behaviors 

Pre-mating behaviors of tarantulas consist of a number of different activities. Courtship rituals are a common pre-mating behavior in tarantulas. This can involve the male tapping the female with his front legs, as mentioned above. Additionally, the male may also create a web or scent trail to help him find the female. During courtship, the male will also often vibrate his body or stridulate, producing a sound like a cricket. 

Mating Techniques

Mating techniques of tarantulas are relatively simple. When the male has successfully identified the female and has performed his courtship rituals, he will then position himself close to the female and attempt to insert his pedipalps into her genital opening. The male will then release sperm from his pedipalps into the female’s genital opening. After mating, the female will usually lay her eggs and guard.

Reproduction of Tarantulas

Tarantulas reproduce by internal fertilization, where the male tarantula transfers sperm to the female using a special organ called the pedipalps, which are located near the tarantula’s mouthparts. The process begins when the male and female tarantula meets for the mating ritual. The male will use his pedipalps to transfer the sperm to the female’s reproductive tract. After fertilization, the female will lay her eggs in an egg sac, which she will store in a burrow or hide until the eggs are ready to hatch.

Egg Laying

After the mating ritual, the female tarantula will lay her eggs in an egg sac. Tarantulas lay anywhere from 50 to 500 eggs at a time and the eggs will hatch anywhere from two to twelve weeks after the female has laid them. The egg sac is usually composed of silk and is often hidden away in a burrow or crevice that the female tarantula has made.

Egg Incubation

After the female tarantula has laid her eggs, they will need to be incubated until they are ready to hatch. The incubation time can vary depending on the species and the environment in which the eggs were laid. The eggs must be kept in a warm and humid environment in order to ensure the eggs develop properly. 

Spiderling Care

Once the eggs have hatched, the mother tarantula will often remain with the spiderlings for several weeks until they are able to fend for themselves. During this time, the mother will protect her offspring and help them find food. Once the spiderlings have reached a certain age, they will disperse and start to live independently.

Potential Benefits and Challenges of Breeding Tarantulas

The potential benefits of breeding tarantulas are numerous. Most notably, they are incredibly easy to breed, requiring little to no care or specialized knowledge. This makes them ideal for novice breeders who may not have the skills or resources required for other species of arachnids. Additionally, breeding tarantulas can be a profitable venture as well, with certain species fetching high prices. 

Furthermore, these spiders are low maintenance, living off of a diet of easily sourced insects, and require little space, making them an ideal pet for those with limited resources. However, there are also potential challenges associated with breeding tarantulas. For starters, tarantula breeding is a time-consuming activity that requires patience and dedication. Furthermore, some species can be difficult to breed, particularly in captivity, due to their challenging environmental needs. Additionally, these spiders can be temperamental, and some species can become defensive and even aggressive if disturbed or handled improperly. 

Lastly, improper handling of tarantulas can result in injury to both the breeder and the tarantulas. Despite these potential challenges, tarantulas can be a rewarding pet to breed. With the right knowledge, dedication, and care, breeders can enjoy the benefits of successfully raising these fascinating animals. Additionally, with proper research, breeders can select species that are suitable for their experience level and manage potential risks associated with breeding. Ultimately, tarantula breeding can be a gratifying activity for those willing to put in the effort and educate themselves.


Tarantulas are fascinating creatures with a unique mating and reproduction process. While it may seem intimidating, successful mating and reproduction of tarantulas can be achieved with attention to detail and knowledge of the species. To ensure healthy and successful mating, it is important to keep tarantulas in the proper environment, provide them with the correct food, and observe their behavior. In addition, proper handling of the tarantulas should be observed to avoid any injuries. With the right knowledge and care, tarantulas can be successfully mated and reproduced in captivity.
