yes, I know there are lots of topics like this, but in my case we're talking about a 4th instar G. pulchra that hasn't eaten since 11/24/10 and I don't see any pre-molt signs.
I have it since 10/31, I've fed him 4 times since i have it 11/3, 11/9, 11/15, 11/24. Since then he hasn't accepted any prey (tried with dubia, laterallis and mealworms). I thought he's gonna molt soon, but nothing. I keep him at around 22-24 Celsius.
