2 or 3 weeks.
one day
I brought a female Praying Mantis indoors and three weeks later she laid her egg case. So it can take a few weeks to a month for them to lay eggs after mating.
Praying Mantises or Praying Manti. Or praying mantids :)
since the Cretacious period
For what i know praying mantises are not deadly at all. They would not need venom to kill because they catch there prey in an iron grip so they can't get away. Then they kill them. From what i know is praying mantises are not deadly not deadly to large things such as a human, unless its 6 foot long, which is impossible.
It takes 2 to 3 days for the eggs to hatch.
Monarch eggs taker about 4-5 days to hatch.
They are green with very long legs, and a small head. They are known for rubbing their 2 front legs together; making them seem to be praying (hence the name).
Cockatiel`s eggs normally hatch after about 19 days.
They don't lay eggs.
ten if long enough the only exception is bad eggs the do not hatch and will crash your game
10-12 days to hatch
