    Kingcup Caltha palustris

    Well, I wasn’t expecting to see the Kingcup in bloom until the spring, but the mild spell we had after the washout of late-summer, has also led to the blossoming of our Bramley Apple tree in the garden.

    The Kingcup is one of my favourite flowers in the watermeadow!  It is also known as the Marsh-marigold.  The Latin name Caltha palustris means Marsh Goblet and refers to the shape of the flower.

    It is thick-stemmed with round water-lily style leaves and flowers like supersize buttercups.  Interestingly, it has no petals.  The burst of colour comes from bright yellow sepals, which in other flowers are the leaf-like wrappers for the buds. 

    The kingcup is perennial, and flowers April to August with occasional blooms at other times.  Ours has only flowered once every spring so far.  This is the first time it has bloomed twice in a year.  It is found in wet and marshy habitats, with oxygen-rich water.

    On the Kingcup you will see a Marmalade Hoverfly, previously noted in August.  I think the other fly is an Oscinella Frit, a type of Frit or Grass Fly (Chloropidae).

  • Marmalade Hoverfly and Lesser Dung Fly

    Marmalade Hoverfly and Lesser Dung Fly

    This is a different hoverfly to the long hoverfly and the Melanostoma mellinum.  It is a Marmalade Hoverfly because of the two moustache-shaped black bands on its abdomen.  Some, but not all, have paler bands like this one, or even white bands.  It is possibly the most common hoverfly in Britain.  It can be found in gardens, parks and hedgerows and loves a sunny spot.

    This tiny fly is almost definitely a Lesser Dung Fly, as it has clearly visible dark wing spots, one on each wing.  There are many species of dung fly, and it is advisable to identify them with a microscope.  However, I didn’t have one handy, so I am relying on the dark wing spots and let’s just say it’s a dung fly that is smaller and less yellow than the Yellow Dung Fly I saw before!  They eat what you’d expect a dung fly to eat!
