Jumping Spider Instar Size Guide
Molting Process in Phidippus regius
Early Instars: The spiderlings emerge from the egg sac in their first instar. In these early stages, the spiderlings are very small and vulnerable. They undergo several molts to grow larger and develop more defined features.
Middle Instars: As they continue to molt, the spiderlings gradually develop the characteristic colors and patterns of Phidippus regius, including the distinctive iridescent chelicerae (mouthparts) and the vibrant body markings. During these instars, they become more independent and start hunting for small prey.
Final Instar: The final molt, usually the sixth to eighth, is when the spider reaches adulthood. At this stage, the spider's sexual characteristics become fully developed, and the spider is capable of reproduction.
