Most people are familiar with honey bees and bumblebees, but look closely and there are smaller furry bees moving from flower to flower. There are around 20,000 described bee species worldwide. Most of these bees are known as solitary bees with only 250 bumblebee species, 9 honey bee species and a number of social stingless bees worldwide. In Britain we have around 270 species of bee, just under 250 of which are solitary bees. These bees can be amazingly effective pollinators and as the name suggests tend not to live in colonies like bumblebees and honey bees.
