How many baby spiders are in eggs?
That's a huge brood. According to National Geographic (opens in new tab), it is common for a single tarantula egg sac to contain anywhere from 500 to 1,000 babies.
Physical Description and Identification
Size: Like most other spider species, the adult females are larger than the males with a length between 6.5 and 20 mm (0.26 to 0.79 in), whereas the males are between 5.5 and 13 mm (0.22 to 0.51 in).
Eggs
After copulation, the females lay about 200-900 eggs in a sac that remains hung from the web. The size of the egg sac itself is nearly the same as the size of the adult garden spiders. The sac is covered in brown silk and is durable enough to protect the baby spiders from strong winds and predator attacks.
Spiderlings
The baby spiders overwinter within their eggs and hatch out to disperse only when spring arrives. The mother spiders die soon after laying the eggs, and can neither wait to protect the sac, nor the newborn offspring or assist them in finding food, and hence, the spiderlings grow up by themselves.

Prolific throughout entire continental United States, Canada, Alaska, and Hawaii.
Habitat
Anywhere with abundant prey and structures to support the web – around light fixtures used at night, or tree branches, tall grasses, and bushes.
Season
Most noticeable in late summer into fall, when webs and adults reach their largest size.
Food
Food sources vary, but typically any small insects they catch in their webs. Some of the bigger orb weavers (Argiope genus) have been observed eating small frogs and humming birds (only if ensnared within the web).
Life Cycle
Most orb weavers appear in the spring, but are not noticed until summer to fall.
Male
The adult males will wander in search of a mate, and as such, typically do not stay on a web for long, if they spin a web at all. Adult males are not observed as much as the females, since they are always on the move, looking for that “Mrs. Right”. Typically after mating, the males will die.
