Blue and white

It was Wednesday morning.  I'd taken the dogs for their first walk of the day and noticed some small tortoiseshell caterpillars feeding on nettles.  A good subject to add to the portfolio so, dogs well exercised, fed and happy to sleep the morning away, I went out again.  The small tortoiseshell butterfly caterpillars were one objective but I also wanted to photograph the southern marsh orchids that have gradually been colonising a local field that is being managed as a flowering meadow by Plymouth City Council.

Of course you get sidetracked.  I'd got my shots of the caterpillars and was walking down to the orchids when I saw a white bluebell in the hedgerow.  Alongside was the normal blue version.  An opportunity not to be missed.  Here's the landscape view.

I'm talking about the English bluebell.  Hyacinthoides non-scriptus.  Honey scented, endemic to North West Europe, with 60% of the population in England and Wales, white sports occur occasionally in nature.  They've been collected and brought into cultivation (not a good idea unless you have a large garden - sheets of bluebells gives a good indication of their invasive tendencies) but it's still nice to see a wild white flower.  Especially when contrasted with the typical blue.  Here's the portrait view.

I remember as a child in the 50's going to a local wood in Grimsby and picking bluebells with my parents.  They weren't as common in the drier East as they are in the wetter South West of England.  Here they're everywhere.  In woods, hedgerows, fields, clifftops - anywhere the black seed can germinate and produce the white bulbs that store energy for their late spring flowering.

Did I get the shots I wanted of the small tortoiseshell caterpillars and the orchids?  Yes.  Here's a sample.

The young caterpillars are communal, clustering together after emerging from the web at the base of the shot as a protection against predators.  For some reason the adults have been in decline in recent years - I rarely saw any - but the last couple of years have shown a local expansion.  May it continue.

As for the orchids it's been a pleasure to watch them multiply over the last 4-5 years as a patch of a field has been left unmown till late summer.  There are hundreds in there now.
