As I dug over my compost heap a flurry of bees flew up from inside. I felt guilty about disturbing them and gingerly put what was left of the nest into a big plant pot. Over the next few weeks my little insect friends went peacefully about their business and built a much bigger nest. I covered the entrance with soil and noticed that junior bees were sent out to rearrange the dirt. Here is a little time lapse film of their methodical efforts.
Sadly after about two months the nest died and became home to an elderly slug, a big spider, seventeen caterpillars and a newt. Not before the bees had excavated an eight inch tunnel into the surrounding soil though.
