One day last week I decided to go out and see if I could find one of the UK’s rarer butterflies…the WOOD WHITE (Leptidea sinapis)..a UK priority species, as this extract taken from the UK Butterflies website explains.
Despite relatively short-term increases, the long-term view is that this butterfly is in decline and is therefore a priority species for conservation efforts. This butterfly has suffered due to a change in woodland management and, in particular, the reduction in coppicing that allows new woodland clearings to develop that provides the conditions suitable for this species. Even improvements in habitat management will not guarantee that the species will reappear from areas where it has been lost, since it is not a very mobile species and may not, therefore, be able to recolonise naturally.
I knew that some had been seen in a wood in the south of Northamptonshire, about an hours drive from home.

A weak sun in a hazy blue sky was doing it’s best to live up to the weather forecasters promise of a sunny and warm day as I set of from home at just after 7am. I was a little worried that my journey was going to be in vain as when I arrived the sun had been replaced by grey clouds and a decidedly chilly breeze, not good conditions for butterfly hunting!

As I’d made the effort I decided to have a wonder anyway and see what I could find and, to my amazement, less than 200yards from the car park I saw my first butterfly…and it was a Wood White!

After taking a few photographs, and feeling rather chuffed at finding my target species in such a short time, I decided to carry on along the track, it looked like good bug hunting territory!, to see what I could find. After about a mile and 2 hours of slow progress (lots of bug photos!) I saw two more of my target butterflies.

Nearly 4 hours had elapsed by the time I arrived back at the car and by now the clouds had disappeared and it was a sunny and warm 20°. After a drink and a quick bite to eat I went ‘exploring’ along another track that led off in the opposite direction and within minutes I’d hit a Wood White hotspot, I walked along the track for about 3/4 of a mile and stopped counting them when I got to 30, they seemed to be everywhere, slowly flitting along the track edge and occasionally having a little aerobatic tussle with a rival, or two!
I was also lucky to see a pair start to engage in a courtship display, unfortunately they where ‘bombed’ by another rival and all three flew off in different directions.
Again taken from the UK Butterflies website…The courtship of this butterfly is an amazing spectacle. Male and female face each other with wings closed and intermittently flash open their wings. At the same time, the male waves his proboscis and white-tipped antennae either side of the female's head. If the female is receptive to these signals, the female bends her abdomen toward the male and the pair mate, staying coupled for around 30 minutes.

Despite missing out on the full courtship display it turned out to be a very successful day, the ironic thing is that about thirteen years ago I actually lived about ten minutes walk from this site and during my regular walks and mountain bike rides around the area I never knowingly saw one of these butterflies!

A couple of days later I went in search of my second target species, this time a day flying moth called the CHIMNEY SWEEPER (Odezia atrata). It was dull, overcast and windy for most of the day  but at around 2.30pm the clouds parted and the sun began to shine and I made a spur of the moment decision to go out and see if I could find any. It was a thirty minute drive to the site where I’d seen them last year and when I arrived it was sunny and 19°.  Again my luck was in as I soon spotted a couple perched low down in the grass, unfortunately it was still quite windy and they were staying well down and only occasionally making short, low flights. After a few failed attempts  I managed to get a few decent images…

It turned out to be not a bad week in the end!

It’s been a while since I inflicted the last lot of ‘bugs’ onto you, so I’m hoping that you’re sufficiently recovered by now and are ready for another dose?

The more that I get into insects the more fascinating I’m finding them…the vast array of bodily variations and adaptations, the patterning and colourings…a beautiful miniature world that the majority of people pass by without even noticing…….until they’re unfortunate enough to get stung or bitten, that is!…thankfully there’s not too many insects that have a viscous streak…there’s got to be a downside to everything I suppose?

Anyway, here’s some bugs, I promise that you won’t get stung or bitten!…

2 Bugs 1 Thick-leg
Thick Legged Flower Beetle (Oedemera nobilis)    Up to 10mm long.  Two things distinguish this green/gold coloured beetle from other similar looking beetles, the ‘swollen’ hind legs (only the male has these) and the ‘ill fitting’ narrow elytra (the hardened wing cases). It’s a common beetle, but restricted to the southern half of the UK, and can be found feeding on the pollen of many wild flowers from April to August.

2 Bugs 3 G-L Sawfly
Green-legged Sawfly (Tenthredo mesomelas)  Up to 15mm long.  This is one of a few very similar looking Sawflies and is very abundant throughout the UK from May to July. Sawflies are so named because most females have a saw-like ovipositor which they use to ‘inject’ their eggs into the plant tissue.

2 Bugs 10  R-h Card
Red-Headed Cardinal Beetle (Pyrochroa serraticornis)  Up to 18mm long.  As it’s name suggests this beetles red head is it’s distinguishing feature, the very similar Cardinal Beetle (P. coccinea) has a black head. Both are found in the same sort of habitat, on the flowers and trees, along hedgerows and woodland margins from May to July. They are confined to England and Southern Ireland.

2 Bugs 7  Malachite
Malachite Beetle (Malachius bipustulatus)  Up to 8mm long.  The large red spot on the rear end of this beetle set it apart from other similar beetles. Found over most of the UK from April to July in the grassy areas within woodlands where the adults feed on grass pollen while the larvae feed on the insects found under loose bark.

2 Bugs 11  Click
Click Beetle (Athous haemorrhoidalis)  Up to 15mm long.  This is the commonest of the UK’s click beetles and is distinguished by the elytra being covered in dense brown hairs. It is found in most wild and cultivated habitats throughout the UK from May to July. The larvae are classed as serious agricultural pests.
Click beetles get their name from having the ability to right themselves by springing into the air, this action is accompanied by a loud click.

2 Bugs 6  G-b Grey Longhorn
Golden-bloomed Grey Longhorn Beetle (Agapanthia villosoviridescens)  Up to 25mm long.  The yellow stripe on the back of the thorax and the yellow hairs on the elytra set this beetle apart from other large British beetles. It can be found in the Midlands and East Anglia in damp vegetation from May to July.

2 Bugs 2 Sloe
Sloe Bug (Dolycoris baccarum)  Up to 12mm long.  I caught this shield bug egg laying out in the open in a very exposed position, I doubt that the eggs survived!  Found throughout the UK along hedges and herbaceous margins where it feeds on the flowers and fruits of many plants. Contrary to it’s name it is not confined solely to Sloe bushes.

2 Bugs 12  Black-Red Squash
Black and Red Squash Bug (Corizus hyosciami) A member of the Shield Bug family this strikingly colourful bug frequents a large variety of plants, originally only found in sandy coastal areas of southern Britain it is increasingly being recorded inland throughout England and Wales and as far north as Yorkshire. Careful identification is required as it can be easily confused with the red and black ground bugs.

2 Bugs 4 G-L Phantom Cranefly
Phantom Cranefly (Ptychoptera contaminata)  Outwardly similar to Craneflies but with some subtle diagnostic features, one of them being the long tibial spurs that are just visible on the hind legs in the photograph. It can be found from late Spring through to Autumn in any vegetated and damp water margins (the larvae are aquatic).

2 Bugs 8  Fly
(Muscid) Fly (Graphomya maculata) This female (males have an orangey brown pattern on the abdomen) is a member of the large fly family that also includes the House Fly and the Stable Fly. They are very abundant and can be found in most vegetated areas throughout Europe where they nectar on various flowers..especially on Umbellifers.

2 Bugs 9  Dance Fly
Dance Fly (Empis tessellata)  Up to 12mm long.  This is a predator fly, it uses it’s rigid downward-pointing proboscis to spear it’s prey, mostly other flies. Found from April to August in most open habitats where it frequents the larger flower heads. It is very similar to and is often confused with Robber-flies.

2 Bugs 5  Mayfly
Mayfly (ephemera vulgata)  Mayflies are aquatic insects, the ‘nymphs’ live in fresh water, but in early Spring the fully winged adults emerge, sometimes in large numbers…and not always in May! with the sole aim of finding a mate as quickly as possible, the life span of an adult is only around one to two days. The first part of it’s binomial name comes from the Greek ephemerus which means short lived or literally ‘lasting a day’.

That’s all folks! (for now anyway!!) I hope you found something of interest and didn’t get too bored?

As always any comments or observations will be greatly appreciated.
