Crickets that have eaten moldy grain can cause something like this. If that is the case supportive care hand feed and watering or force feeding is called for and something you would get from your vet. Don't feed any more crickets if you think they have eaten moldy food.

From the looks of the little guy and by what you're saying...I'm not sure waiting until tomorrow is going to help. In fact...it almost seems like he may not make it through the night. I hope he makes it...I hope he makes a full recovery, and yes please keep us posted. Poor lil dude!
