Euglossa bazinga is a Brazilian bee species. It has the longest tongue in proportion to its body size. It is named after Dr Sheldon Cooper's 'tricked you' catchphrase in The Big Ban Theory because it tricked the scientists into thinking it was a different bee species.

Tree bumblebee, aka bombus hypnorum, has only been in the UK since 2001. It's ginger and black with a snow-white tail. Though it sounds like a sleepy bee, the name might derive in a roundabout way from the use of moss to stuff pillows: the tree bee loves an old mossy bird's nest.
