Most males get away, though many may be wounded in the process. She stores the sperm alive in a special organ until it is time to lay her eggs. A Male Burrowing Spider entices the female to emerge from her burrow by drumming with his feet. The eggs are wrapped in a silk cocoon, some mothers add a good amount of urticating hairs in the cocoon to protect her eggs. They hatch in about 1-2 months.
Some mothers guard their egg cocoons in their silk-lined burrows.
Newly hatched spiderlings can be very large and usually stay in the mother's burrow for a while before dispersing. Females are among the longest lived spiders, living for 20 years, some even 30 years. Females can take 8-10 years to reach maturity, and they moult every year or so. Females can replace lost appendages as they moult. The mygalomorphs seldom put up a fight and passively await their fate as the wasp creeps up and stings them in their soft abdomen.
