Insectivora

The hedgerows and the edges of country paths are home to an immense variety of small creatures, especially those which aren’t in the firing line for agricultural chemical spraying, and it can be easy to overlook them.

Last weekend I spent a morning chasing insects around and I followed a red admiral butterfly into a thicket of nettles where it sat tight with it’s wings closed. Over the next twenty minutes it very briefly opened its wings, but only partially, but enough to enable me to see that its colours were pristine:

And then it opened them fully, and the colours really were sumptuous:


…well worth half an hour stood in a nettle bed!

But I thought the half hour definitely wasn’t wasted when I looked down at my feet and saw this cluster of peacock caterpillars eating nettle leaves:

I moved to one side to get some pictures of the caterpillars, and fortunately after I’d spent some time doing that the red admiral was still in situ.

Peacocks are hardy butterflies which can be found over most of the UK including the Shetland Isles and can be found hibernating in garden sheds. They emerge from hibernation at any time of year if the weather is warm enough, they mate in March and lay eggs then the caterpillars can be seen from the middle of May into July.

Not only are they hardy, they are quit beautiful too. A close look at their wings reveals a fabulous array of brightly coloured detail:

Male peacocks hold fort in their territory and wait for passing females to pass by when they fly up to greet them and attempt to mate. Male and female peacocks are very difficult to tell apart and watching the males performing this courtship behaviour is one way to differentiate the genders.

And close to the same spot I was looking at the flowers and I spotted this hoverfly cleaning his eyes:

…and this beetle wandering over a convulvulus flower, I don’t know what it is but it has gorgeous colours:

The brambles in the hedgerows were also full of bees in the sunshine, many species of honey bees and bumble bees were harvesting nectar from the flowers:

And than this marvellous creature was hunting in my kitchen last week:


Violet ground beetle, isn’t he magnificent!

Violet ground beetles are carnivorous, as are their larvae. They hunt at night and hide up during the day under log piles or other cool dark places. They eat a variety of insects, including a number of species that gardeners would be glad to be rid of. They’re big beetles, around 3cm long, and they have irridescent blue or violet edges to the thorax and wing cases. So don’t use chemicals in your garden – let these guys get rid of your pests!

And now I’m looking forward to some warm sunny July days when the surrounding fields are full of butterflies. I’ll share some more insect photographs with you then.

Orange tip

I am of course referring to the butterfly, not an unsightly medical condition. I’ve spent plenty of time chasing them along hedgerows waiting for one to settle on a flower, but in vain, and you may recall that in a previous post I said that the orange tip was extremely difficult to photograph because they rarely settled.

That was until last weekend when, the weather was sunny, warm and calm so I went for a walk on Guns Lane to the north of Histon. I was rewarded fairly soon into my walk by a male orange tip settling on a plant on the edge of the pathway and allowing me to encroach within just a few inches:


Male orange tip. I think his underwings are exquisite, and it’s perfect camouflage when he’s perched on a cow parsley flower head.

This fellow was a good omen. Several hundred metres further along the path where the dense hedgerow thinned out into more open territory lined with cow parsley there were many male and female orange tips and they were all intent on mating on this particular morning.



Another male orange tip, this time with his wings open. And the colours on top are gorgeous too.

The female of the species doesn’t have the orange tips but is still distinctive from the other white butterflies:

Female orange tip. She is aware of the presence of males and is pointing her tail in the air in preparation for mating…

…and a few seconds later a male flew within a few centimetres and her reproductive organs are clearly visible opening up here in response to his presence.

The female above didn’t mate in this instance, but:

This pair were mating on the ground close by

I promised some pictures a few weeks ago of orange tips in the post ‘Local Lepidoptera’ so I was very pleased to capture this series of the mating behaviour so soon after.

Local Lepidoptera

The class of insects known as the ‘Lepidoptera‘ is the one that encompassses moths and butterflies. Many species of both have emerged from hibernation and can be seen aplenty in gardens, parks and in the countryside.

Speckled wood (Pararge aegeria) and orange tip (Anthocharis cardamines) are abundant in scrub and hedgerows.

The speckled wood is an interesting butterfly for a couple of reasons. It has a north/south colour variation where  more northerly individuals have  whitish spots and more southerly ones have orange spots. The other unique feature of this species is that it can overwinter as both a larva and a pupa resulting in adults emerging all the way through from Spring to Autumn.

I don’t have a good picture of an orange tip as they are very difficult to catch stationary. I watched one sat on a cow parsley flowerhead for several minutes last weekend, but of course I’d left my camera at home. The males have a 40-50mm wingspan, creamy white upper parts with big orange patches on the wingtips which alaso have a black margin. Underneath they have wonderfully intricate green lacework which makes highly effective camouflage. The females don’t have the orange tip, which is thought to be a warning to predators that they are unpalatable, but they are easier to see on food plants as they are not busy looking for mates in the same way the males are. Photographs to follow, hopefully!

A few red admirals (Vanessa atalanta) have been spotted by me in Histon so far this year, although not more than two or three, but in the last two weeks large numbers of small tortoiseshells (Aglais urticae) and holly blues (Celastrina argiolus) are flying around in the hot sunny weather.

I haven’t seen many interesting moths yet this year, but late one evening last week, whilst quietly watching TV, this beauty emerged from behind the sofa, to the general consternatiion of all in the room, fluttered around very rapidly for several seconds before homing in on a lamp and alighting inside the shade:

As you can imagine, her choice of resting place gave an additional challenge to the photography but I like this picture. The male is even more colourful with orange hindwings and believe it or not the emperor moth, Saturnia pavonia, is native to the UK, not an import from the rainforests! Emperor moths are big with a wingspan over 7cm, and they live on moors and in open countryside where they feed on brambles. The males are out and about in daytime looking for mates in April and May and the females are abroad at night, I guesss looking for safe places to lay eggs. It is the UK’s only resident member of the Saturnidae family.
