Hey guys, I've got a question about my Lasius niger colony. This colony has been going for around five years now and have been moved into a larger formicarium last summer. Around that time last summer the queen had started laying eggs that will be over wintered as larvae, which they did. The larva cocooned a couple of days ago and are much larger than any cocoons that I have seen before in the colony's five years of existence. I assumed this is a normal thing as the more food (they were provided with more food than ever before) fed to the larvae will define what caste they will be, so I thought that these cocoons will be larger workers than the last generation. (Please tell me if this is wrong). Oddly, a cocoon hatched today and it was a male that crawled out of the cocoon. We all know that male ants are born from infertile eggs. But now I am confused. How can an fertile egg change from a fertile egg to an infertile egg? I am also assuming that the queen has laid a fertile egg as she has never produced male ants before. I hope this makes sense.
