Unusual hoverfly


My partner and I visited over Spring Bank Holiday. Had an amazing time and saw some new stuff to us. For me one of the most exciting things was spotting a very localised hover fly that doesn't seem to have been recorded at the site before (at least not on NBN or GBIF). I was wondering if someone can confirm if it is a new sighting for the reserve. It is a very convincing bee mimic so it is possible that people have overlooked it as a bumblebee in the past

.Criorhina floccosa

She's called Criorhina floccosa and I was very happy to get this confirmed today by the UK Hoverfly Facebook group.,

  • Thanks for this, the only record I could find was of Criorhina asilica, so a great find of floccosa - whereabouts did you find it?
  • Thanks for this Matt - Well chuffed to find a new species for the reserve, that can't happen too often :)
    I saw her on the path that leads from the stairs to the cafe tables to the ponds and viewpoints below the sand martin nests.
  • An exciting find.
    I only have access to a copy of our species lists as of 2017 at present, and she doesn't appear on that list. Two other species of Criorhina are on that list. I know lots of species have been added since, but I don't know if this is one. I will let our ecologists know and double check with them whether it's on the reserve list. A good example of why it's important to try to take a photo of any mystery species.
  • Our ecologists have very speedily come back to me to confirm that this is the first record for the reserve. Very well done on your find
  • In reply to Ian Barthorpe:

    Excellent - many thanks Ian for confirming this,. I've never found a new species on a reserve before...
    Well chuffed!! If it helps I have also added the species on iRecord and informed the UK Hoverfly group as well.
    Off to bask in my own satisfaction for a bit!
  • It's a good feeling, isn't it. My son found a new sawfly for the reserve a few years ago, despite not having a clue what it was at the time, and our volunteers are often finding new bees and wasps, Well done, and thanks for reporting it to us
