When will it hatch? How many mantids?

I have a Ghost Mantis Ootheca.
It was laid 20 days ago.
It is 3.15cm long (approx)
I have had it for 9 days now and it has been kept at 22-24 degrees C during the day, and down to 18-20 degrees C at night.
It gets a light mist twice a day.

1. WHEN WILL IT HATCH?

2. HOW MANY WILL HATCH?

The closest guess to each gets one of the nymphs when they moult to 2i.
If someone guesses both correctly they get 3 of the nymphs.

No double guessing (you cant guess the same as someone else).

please put your guesses in the format of:
_scorpio_ - 1. 11/11/1945 2. 1,000.000
*~BEX~* - 1. 34/56/7890 2. 1
etc...

If you are going to keep it at that temperature all the way i'd say:
Scorpeace - 1. 27th october 2011. Will give 21 nymphs

Could you post a pic of the cocoon and let me look at it and maybe change my answer? If I cant change my answer when you post it, dont post it

nah, you'll have to guess from the length, no pic

Looks like I will win no matter what I say xD Comon people! Guess!

I know nothing of these and I'm not interested in nymphs. The person who guesses closest to the number I'm thinking of can have my nymphs if I win!

Annababe- 1. 10/21/11 17 nymphs

Bedlam predicts:
Oct. 23 with 18 Nymphs.

What happened to the ootheca?
