    Bumblebee Plumehorn (Volucella bombylans)

    Noticing the cuckoo flowers under the alders, was like welcoming back old friends.  There were a couple of bumblebees on them, with white tails.  I couldn’t remember whether I’d already counted the white-tailed bumblebee, so I took some photos anyway.  But wait a minute!  Look at its head!  Not furry like bees, but a big-bug-eyed fly’s head.  I didn’t notice till I looked at the photos on the big screen of the laptop!  What we have here is a bumblebee plumehorn – the best bumblebee mimic in town!  Yes, it’s a hoverfly.  There are two variations – red tailed and white tailed.  Obviously, this is the white-tailed version.

    Plumehorn refers to its antennae, which are plumed.  This hoverfly lays its eggs in the nests of bees and wasps.  Sometimes their larvae eat the host larvae.

    Early Bumblebee

    I spotted this bee on the grass in a rare patch of sunshine on Monday.  I assumed it was a buff-tailed bumblebee because of its orange bottom, but it turns out that buff-tailed bumblebees have a white tail, which I should have remembered from my white-tailed bumblebee post.  So, which bees have an orange tail?  And stripes?  The red-tailed bumblebee is black apart from its tail, so no stripes.  The bilberry bumblebee has a fiery red tail but is in decline and prefers higher altitudes. 

    The Early Bumblebee is described as the only bumblebee to have a truly orange tail.  It has two yellow stripes, which in males can be wide enough to cover a good part of its head and upper abdomen.  It lives up to its name by waking up early in the year.  In fact, new queens do not hibernate at all, but start a nest straight away.  This bee likes white clover, lavender, sage, thistles, and flowers in the daisy family. It is quite common and favours flower meadows and cultivated gardens.

    White-tailed Bumble Bee

    I’m playing catch-up for the next few days, as I have a back-log of photos to identify and log (and also sciatica, so I am not tackling the steps down to the watermeadow).  This is a white-tailed bumblebee on some toadflax.  It is similar to the garden bumblebee and the buff-tailed bumblebee, but its bands are bright yellow, like lemon curd, whereas those of the buff-tailed bumblebee are more orange-yellow, and the garden bumblebee has beige stripes.  They all have a white bottom, though the white-tailed bumblebee has the purest white. 

    They can all be found in a variety of habitats, as long as there are flowers present.
