A few years ago, I was extremely disappointed to find out that there are parasitic bees. Every year, I had Solitary Mining Bees returning to the garden and I used to watch them diligently dig their holes. They would spend each day flying to and from their hole with bags of coloured pollen on their legs. One day, I saw a red insect also go in and out of the holes and I retrieved the computer. Unfortunately, the insect was a parasitic, female Sweat Bee – they do not collect pollen and they lay their eggs in the nests of other bees (their larvae eats the larvae of the other bee!)
To make the story worse, the following day I found an injured black and white Bumblebee. Once again, I retrieved the computer and found out that this too was a parasitic species of bee. I left it to its natural fate. These types of bees are called Cuckoo bees after their nest-stealing nature.
