Mating and Reproduction of Psalmopoeus cambridgei tarantula

One of the fascinating aspects of the mating process of the Trinidad Chevron Tarantula is the fact that females don’t lay eggs. They inject a mix of sperm into the male’s penile spines. Mating of tarantula depends on season. Females choose their mates based on the length and size of their spines. A more extended spine means a better quality male. After mating, the female spins a cocoon around the male and lays between 20 to 50 eggs. Once the eggs hatch, the young spiderlings feed on the male’s sperm for several weeks before they start to spin their cocoons and develop into adults. When the young hatch, the first thing they do is eat all of the yolks from the egg sac, and only then will the baby tarantulas begin their metamorphosis into adult form.
