Tarantulas of this genus are long-lived, with males reaching maturity at seven to eight years, females at nine to ten. While males only live up to a year after their final moult, females may live for a further ten years. Sub-adults and adults moult at the end of the dry season (November to June), after which males begin their search for mating females. The egg-sac is laid after the female moults, and hatches three to four weeks before the rainy season begins (4). Mexican rustleg tarantulas tend to be active after dark, but can also be active during daylight, particularly in the morning and evening (2).
