No one can help me on the bulb forum. I think this was a calla lily bulb, it was big and healthy. I dug it up by accident and found it swarming with white insects that looked like termites, but they do not have big heads. It was not like a grub, they move very fast and there were like a thousands of them. I did discard it, but I want to know what it was. Has anyone found something like this? I would have taken a photo, but it so disgusting, and I was afraid it would spread to other plants.
