Hutchinson's Bank

As you walk onto Hutchinson's Bank from a convenient parking spot, the sides of the path are lined with wild strawberries.  These should be fruitful later on.  The fruits are small, but tasty.  However, I am wary of eating fruits which are positioned where dogs can be walked.

In the chalk cutting, there is what looks like a discarded piece of concrete, though it might have some purpose; this is a well-cared-for spot and rubbish would have been removed.  This Beefly was basking on it.  It might look a bit like a bee, but closer up it can be seen to have a fly's antennae and only two wings.

Beeflies lay their eggs in the holes made by solitary bees, and their larvae eat the bee larvae when the eggs hatch.   That long proboscis is not a sting.  It is used by the fly to eat pollen while hovering above a flower.

Horseshoe Vetch, Hippocrepis comosa.  Hutchinson's Bank, 24 May 2016.

Horseshoe Vetch and the rather similar Kidney Vetch grow here.  These are the larval food plants for Chalkhill Blue and Small Blue butterflies.  The butterflies are only found in association with these chalk-loving plants.

Along the top path is a stretch rich in Sainfoin, a plant in the pea family that looks similar to a Lupin. 

Woodruff, Galium odoratum.  Hutchinson's Bank, 24 May 2016.

A triangle of woodland at one end of the bank has several ancient woodland indicator species, including lots of Woodruff, its white flowers making light patches in the shadier spots.

Wood Sanicle, Sanicula europaea. Chapel Bank, 24 May 2016.
Across the road is another special site, Chapel Bank.  The path leads through an area rich in Sanicle, another ancient woodland indicator species.

Grizzled Skipper, Pyrgus malvae.  Chapel Bank, 24 May 2016.

On a chalk slope on Chapel Bank I photographed this Grizzled Skipper, another butterfly with a limited distribution. 

An unusual feature of Chapel Bank is a swathe of Marsh Thistles on one of the slopes.  When mature they can overtop me, and en masse they can be quite imposing.  At the moment they are still quite immature.  There is a much smaller stand of these plants in Beacon Wood, and even they were impressive.
