Subject: I think these are eggs….

Your letter to the bugman: Hello, I have a vivarium for Poison Dart Frogs and found some small white nodules growing under a piece of wood. My hope is that this is some sort of fungus or mold. But my concern is that these are the eggs of some bug that could do harm to my frogs or their eggs.
The piece of wood was harvested many years ago from a forest in Ontario. I included a picture of the wood with suspicious object, as well as a picture of my cute frog!

These do not appear to be eggs, and we believe your suspicion that they might be fungus or mold is probably correct. Friends of ours in the Los Angeles area formerly bred Poison Dart Frogs. They had several pairs that bred in bromeliads, but alas, the vivariums were discovered by invasive Argentine Ants that killed the frogs.
