Blackbottle - Protophormia terraenovae

    Alt Name
    Northern Blowfly

    This is a fairly large, dark blue blowfly. It will often fold its wings tightly over the abdomen at rest which can lead to confusion with the similar Protocalliphora azurea. However P. terraenovae can be separated by its much darker colour and the absence of any dusting on the thorax.

    Identification difficulty

    Seems to prefer exposed habitats such as dunes and moors.

    When to see it

    Throughout the year but peaking May-August.

    Life History

    The larvae normally develop in carrion but may also feed within the tissues of living mammals.

    UK Status

    Frequent in Wales and Scotland but scarce in the Midlands and South.

    VC55 Status

    Believed to be scarce in Leicestershire and Rutland. Prior to the Spearwort Fields record there had been just one other sighting in our counties at Grace Dieu Wood in 2011.
