Cobalt Blue Tarantula Sexual Reproduction
Cobalt blue tarantulas are capable of reproduction after they have undergone a final molt, emerging as adults. As spiderlings, these tarantulas are greyish blue in color. Adults are primarily solitary, with males and females only socializing for reproductive purposes.
Vibrating their bodies, males carefully approach the burrows of female specimens. They perform tapping rituals in order to entice females. Receptive females will either exit their burrows or invite males inside to mate. Following fertilization, females lay eggs in egg sacs. The eggs hatch into spiderlings within a few weeks.
The success of cobalt blue tarantula sexual reproduction depends upon a variety of factors. As is true some other spider species, females may attack and consume male specimens either prior to or immediately following insemination. Temperature fluctuations may upset timing and parasites can also destroy egg sacs.
