Summer trundling on

AS summer trundles on and the longest day passes, subtle changes can be seen; new flowers come into bloom, certain butterflies appear, bird song changes or stops completely.  Together these observations build up to a set of signs that are predictable, but also delightful.

This week one feature that I have been able to capture is the emergence of small skipper, ringlet, meadow brown and marbled white butterflies.  The excellent book "The Butterflies of Britain and Ireland", which I can't recommend highly enough, gives a helpful insight into which species to expect where and when.  The marbled white adult, for instance, which has a southern distribution, emerges in late June and the disappears in August.  Personally I associate it with the flowering of pyramidal orchids in tall upright dominated brome grassland, where yellow vetches and knapweeds add flecks of yellow and purple to the sward.

One slight obsession that I have recently acquired is trying to capture images of flying insects.  This needs to be done during the warmer part of the day, as in the evening butterflies are often stationary on grasses as they settle down for the night.  The evening does, however, enable me to photograph them closely.

Of course at this time of the year there are masses of different plant species at the height of their power, so to speak.  We visited a local nature reserve where I came across a hidden valley, full of common valerian growing on the edge of a clump of trees.  I normally associate this with woodland glades, but here it had invaded the grassland in amazing profusion.  The small skipper butterflies particularly liked the nectar on offer.

I also found this particularly fine example of a knapweed broom rape.  This is a parasitic plant which grows on knapweeds' roots, as the broomrape has no chlorophyll itself.

On an open meadow, where the grassland had been allowed to grow tall, the meadow crane's-bill is now coming into flower.  It was buzzing with bees and the flowering of this plant is strongly associated with mid-summer for me.  When the petals fall from the plant the resulting immature seed pod, and sepals left behind, do look like the head of a crane, approximately.  I suppose were we to name it nowadays we might struggle to find a suitable bird - maybe a heron's bill...doesn't quite work does it?

On another site this week where I was searching for butterflies, deer, flowers etc. I came across this local speciality in wonderful blooming brilliance - the Bath asparagus.  It has been substituted for the veg of the same name in the past.  It is a large, elegant flower that is usually found along woodland rides and hedgerows.  This one was in tall grassland.

  1. A fine set of photos. Personally I have quite enough trouble trying to photograph insects at rest let alone in flight!


Have your say...
