Hi! I would just like some clarification please! We noticed today that we had what appear to be bees flying in and out of a hole in the wall on our flat. We’ve lived here for years & it’s the first year we’ve noticed it. We’ve done googling and suspect them (it?) to be Masonry Bees but would love clarification as we’re both wimps when it comes to flying stinging things and would love to know where we stand for our own sakes but also that of the cats who seem to think the hole provides them with flying toys! And we obviously don’t want either to get hurt. It doesn’t look quite right for a masonry bee but doesn’t look like honey bees / bumble bees / hornets etc so we turn to your expertise! Thank you!

Dear Tofu K,
This is a harmless Drone Fly,
Eristalis tenax, and we were puzzled by your observations that is was “flying in and out of a hole in the wall,” and we learned something very interesting on Nature Spot where it states they can be observed:  “Virtually all year round. The female hibernates in buildings and crevices but will emerge on warm days in late winter, leading to it being seen in virtually every month of the year.”  Larval Drone Flies are known as Rat-Tailed Maggots.  More information is available on UK Safari.

Thank you for your prompt reply! I was expecting to wait a little while as the websites state you may have to.
Thank you for putting our minds at ease! I was concerned it was some beastly giant buzzing bee we were going to have to live with! And very “pleased” that they sometimes mimic bees – it means we’re not going completely crazy!
Glad you learnt something new about them too!
