2017 in Butterflies

Like the bees in my last post – butterflies are summer’s companions. Whilst the bees add movement and sound, their gentle buzz providing the background to many a summer’s day, the butterflies are all about the flair and colour.

Below are a few of my favourite encounters as we moved through 2017.

Green hairstreak – Callophrys rubi

This is a species I have only ever seen briefly before, flitting in the low grasses as we walked The Ridgeway through Oxfordshire a few years ago. A hunt around Barnack Hills and Holes in May soon turned up a hawthorn shrub with several males standing guard over their patches of territory. This one was settled on an unopened flower bud, poised and ready to spring into the air as soon as another flew past and questioned his ownership of this space. You can read more about this encounter in this blog post!

Green-veined white – Pieris napi

With the exception of a couple of rarer species, it is easy to overlook our white butterflies as most people view them as pests in the garden. But like almost anything – they’re beautiful when viewed in their own right and on their own merits. My favourite part of this photograph is those chequered blue eyes as this butterfly feeds on forget-me-not flowers at Treswell Wood.

Small pearl-bordered fritillary – Boloria selene

We were walking through the dunes and forest at Newborough in Anglesey in May and spotted this static shape at the side of a path – a small pearl-bordered fritillary resting on the seedhead of a plantain. It’s rough brown textures gave it excellent camouflage. This species is widespread across the UK but only occurs in discreet colonies, commonly in the clearings in deciduous woodland but also marshland and moorland further north.

Ringlet – Aphantopus hyperantus

This is a common species of grassland and woodland habitats, but one which always delights me. The veins in the soft-brown wings are such good parodies of those found on the leaves it settles amongst, and the five eye spots are striking. This photo was taken at the Hills and Hollows behind Grantham, the butterfly sheltering amongst the grass on a windy afternoon.

Marbled white – Melanargia galathea

This white is actually more closely related to the browns than the other whites, despite name and appearance. It is a species I usually associate with the counties of Warwickshire and Oxfordshire as these are where I have encountered them most often on walks and surveys, so it was lovely to find a healthy population down the road in Bedford Purleius. This was taken in the meadow close to the carpark, along with the silver-washed fritillary pictured below.

Burnet moth – Zygaena sp.

Technically not a butterfly but a dayflying moth, I felt I had to include this photograph. This was taken at Lolly Moor – a Norfolk Wildlife Trust reserve – when I called by this year. The marsh helleborines were my main aim but there were many other orchids and these burnet moths were bouncing between them. This is one of the five-spot burnet moths, but I am unsure whether the ‘regular’ or the narrow-bordered. Any tips welcomed!

Small copper – Lycaena phlaeas

Some years I see this delicate little butterfly everywhere but others it is a real treat to encounter. Sadly 2017 was the latter – the only time I came across this species was whilst walking on a path above the Thames in Oxfordshire. The set-aside margins in the fields were particularly species-rich, drawn from the local wildflower meadows, and this was one of several species of butterfly enjoying the flowers on the day we were there.

Silver-washed fritillary – Argynnis paphia

This was a rather ragged specimen but its grace and presence was un-diminished – they stood out a mile flying alongside the marbled whites in the meadow at Bedford Purleius. This is our largest fritillary species in the UK and gets its name from the streaks of silver on the underside of the wings.

Wall brown – Lasiommata megera

A walk from Cheddar up the gorge to the quarry at the top rewarded me with this butterfly. The wall used to be much more common across the UK but suffered severe declines and now has a much smaller distribution. This is certainly the first time in a number of years I have come across this butterfly.

Common blue – Polyommatus icarus

Taken at sunrise in Muston Meadows, this common blue had spent the night roosting on the seedhead of a black knapweed and was waiting for the morning rays to warm it before taking to the wing. These little blue butterflies are abundant within the grasses, feeding particularly on the bird’s foot trefoils and other meadow wildflowers.

Red admiral – Vanessa atalanta

The last butterflies I saw in 2017 were those set to see out the winter in their adult form – the red admirals, small tortoiseshells and peacocks. Ivy flowers provide an abundant source of nectar for these late-flying species and they joined the bees and hoverflies on the flowers beside Grantham Cemetery.

2016 in Butterflies

I thought I had probably seen my last butterfly of 2016 when I started to put together this collection for 2016 – only to see a peacock flitting around on my lunchtime walk yesterday. Sunny weather or disturbance can bring out some of our hibernating species during the winter so the ‘season’ never truly ends!

This green-veined white butterfly was feeding on the greater stitchwort flowers in the Nottinghamshire Wildlife Trust reserve Treswell Woods earlier this year. A closer view reveals the yellow pollen from the anthers on the legs of this butterfly which will likely be transferred to the next stitchwort flower on which the butterfly alights. This act of pollination is the reward which the flowers get in return for their nectar they provide.

This is a close-up photo of a orange-tip butterfly – I love the chequer-board green eyes. This individual was resting with folded wings on a white flower and their camouflage really is superb in this pose – until their open their wings and reveal those gaudy orange wing-tips from which they derive their name.

This year was a good one for dingy skippers – I was lucky enough to see them at a number of different sites.This was at a Warwickshire Wildlife Site – Harbury Spoilbank – where grizzled skippers and green hairstreaks are also to be found. This is a male and a female pre-mating in the low vegetation.

Another skipper from another Warwickshire Wildlife Site – this time at Ufton Fields. This is the grizzled skipper, a tiny little butterfly which could easily be mistaken for a moth at first glance as it zips past. This one is feeding on a speedwell flower.

This is one of the UK’s rarest species – the wood white taken at Ryton Woods in Warwickshire. I took a walk around the rides hoping to spot this species and was just about to give up hope when this one appeared, bouncing along the edge of the rides. Their flight is slow and delicate and the males spend much of their time patrolling in search of females on the vegetation. I followed this one a while and got just one or two photos before he fluttered on over some dense scrub away from the path and out of sight.

This is a common blue butterfly perched on one of their favourite food plants – the bird’s foot trefoil. I like this photo as you can see the curled tongue protruding. This long tongue straightens when they feed, allowing them to reach nectar from deep within the flowers and to access resources that many insects cannot.

This photograph of a common blue was taken at sunset at Muston Meadows NNR in Leicestershire. The butterflies settle on vegetation such as this, always seemingly adopting this downwards-facing pose, at the end of the day. This one tried several locations before finding a position it was happy with. The butterflies spend the night roosting like this, ready to awaken when the temperatures rise again in the morning.

This orange tip was displaying the colouration which gives the species its name, although it is only in fact the male butterflies which have orange tips – the female butterflies have black tips. Orange tip butterflies favour flowers of the cabbage family and this individual alighted and then departed several non-cabbage flowers before settling and drinking deep from these dame’s violets growing along The Drift SSSI.

I think it’s only fair to include a raggedy painted lady butterfly in this collection, considering the journey these butterflies make to get here. This was taken feeding on hogweed along the Grantham Canal – many miles inland from the sea across which this butterfly had flown to get here. This species does not breed in the UK which means that every individual you see will have migrated from the continent.

I rather liked the angularity of this photograph of a marbled white in a slightly unusual pose. I do not know of a site local to me where these butterflies are found, but they occur in good numbers in many grassland sites in Warwickshire where I have spent some time this summer. These butterflies seem to favour thistles – newly emerged individuals will alight temporarily on all sorts of purple flowers – from ragged robin to orchids – until they get their eye in for the thistle flowers they are seeking.

2016 wasn’t a good year for the small tortoiseshell with low numbers recorded through much of the summer. I saw a few more in the later months, such as this one feeding with several others on a patch of thistles in a pasture field. Nettle and thistle often come to dominate patches of higher nutrient ground within pasture fields. The imago – adult butterflies – love the thistle flowers, and their caterpillars feed on nettle, so this combination of species is ideal habitat for small tortoiseshells.

A red admiral to finish – these are one of our few species which hibernate along with small tortoiseshell, comma, peacock, speckled wood, clouded yellow and brimstone butterflies. This individual had found the patch of naturalised Michaelmas daisy in the grassland above Grantham in October, along with a range of bees and hoverflies – and was taking advantage of the nectar source and autumnal sunshine before finding somewhere dark and stable to fold its wings and await the spring.
