Bombus lucorum
Bumble Bees are known to everyone and the various species' make up one of the most familiar group of insects. Whilst some bees are solitary, Bumble Bees are social insects, forming small colonies during the Spring and Summer months. After pairing in the late Summer/Autumn, only the young Queens survive through the Winter to start new colonies the following Spring. But there is a seemingly increasing trend for new colonies to be started by some species, later the same Autumn after pairing and if conditions are favourable. Both Queens and workers are now sometimes recorded during mild Winter days in the south-west UK.

B. lucorum is very similar to B. terrestis and best distinguished by it's more lemon yellow banding, than the typical darker yellow banding of B. terrestis . The end of the abdomen of B. lucorum is also pure white, but it can still be confused with a B. terrestis which has little buff colouration at the end of the abdomen. However, the buff colouration is often distinct enough to make identification failry easy.
