I will check the temperatures tomorrow. The cages are low-lying, with large gauge screen covers, so I did not anticipate this being a problem. However, it could be something like this. As far as food goes, I will try to get some moths this evening and offer them in the morning, and I am expecting more crickets tomorrow. Could it be that overnight temperatures are too low? I believe it was 59F last night. Anyhow, thanks for the help and let me know if you have any other ideas...
