30 Days Wild – Day 21

I contrived to have the longest day off this year, the first day of my weekend, so I suppose it will also be the longest weekend, at least for daylight. Remarkably it was not raining so I took the opportunity to visit Broughton Down again, a gem of a site and for most of the time we had it to ourselves. It is proper downland as you imaging it should be, or at least some sections are, some still suffer from scrub encroachment, but a long term program of control is taking effect.

The top of the Down is especially good for fragrant orchid, of which there are literally thousands.

They come in varying shades.

Usually as single flowering spikes, but sometimes in groups.

And to cap it all they are really fragrant too.

There were some other orchids, in the hollows especially, there were common spotted orchid.

And thinly scattered through the fragrant orchid were pyramidal orchid.

There were good numbers of butterflies, perhaps commonest were small heath, impressive as they are seriously reduced in numbers at most sites. Perhaps next most frequent was dark green fritillary, then brimstone, meadow brown, marbled white and common blue. None of which I got pictures of, although as I staked out a group of large scabious flowers I did get a Conopid fly, probably Sicus ferrugineus.

My other insect highlight remains unidentified, but is very smart, if anyone recognises it I would love to know.

Back home in the garden I did manage to get a picture of a meadow brown, one of at least three in our mini-meadow.

I also got a shot of a leafcutter bee on a geranium.

30 Days Wild – Day 14 – Concrete to Orchids

Blashford’s brilliant volunteers were working hard again, this time on a project to produce a grassland on the former concrete block plant entrance. This is a project with a lot of difficulties, the site was abandoned fro three years and much of it got overgrown with bramble. The old hard standings and buildings were broken up leaving a mix of rubble, gavel and a very little soil. This might sound a bad start for a grassland, but it actually has potential, the most diverse grassland habitats are those with very poor soils and this area has a very, very poor soil. From this poor beginning we are making real progress, the old tarmac entrance now has flowering ox-eye daisy and bird’s-foot-trefoil and this is in just the second season since seeding. Perhaps most remarkably as we headed back for a cup of tea we found a flowering bee orchid!

I suspect it may have come not as a seed but as a small plant along when some of the soil was being moved around, but clearly it is doing well. When I returned in the afternoon to do some more mowing of bramble regrowth I came across a pyramidal orchid on the bank that used to edge the road. The soil there was not so disturbed, so I would guess it had arrived some time ago.

Although the day had started drizzly it dried up, as it always does on a Thursday morning, famously it never rains during our Thursday volunteer sessions, whatever the forecast might say.

By afternoon it was hot in the sunshine and as I ate lunch I saw lots of insects. On bramble flower behind the Education Centre I found a yellow-and-black longhorn beetle.

I also saw several dark bush cricket nymphs.

What’s in My Meadow Today?

The wild carrot that I featured before the flowers open a while back is now in full flower and attracting insects.

There are several species of dronefly, all named for their similarity to male honey-bees. I think this one is Eristalis pertinax, but actually might be E. nemorum as it looks a little bright to be pertinax.

The reason for my late post of this time is that I was out again last night surveying nightjar. I heard possibly one that moved about or up to three, unfortunately I could never hear two at the same time, so I cannot say with certainty that there was more than one.

30 Days Wild – Day 29: A Grave Day

Luckily not as bad as it sounds, in fact actually a “Jolly”. Each year the volunteer team have a day out at Kitt’s Grave, it is part of the Martin Down National Nature Reserve but belongs to the Wildlife Trust. Although it is managed by Natural England we usually go up top do a couple of tasks each winter, although we did not make it last season. We have been assisting in the clearance of scrub to open up glades and ultimately restore areas of chalk grassland. As we have been doing this for some years it is interesting to see how the habitat has been developing, I am pleased to say that the answer is well so far.

Our visits are usually a great chance to see lots of butterflies, but as we left the car park this morning we were wondering if we would see any at all. Luckily we had a good start in other ways, with a turtle dove purring away in the thorns. Crossing the road to Kitt’s Grave we heard a lesser whitethroat and heard and saw yellowhammer and corn bunting. Then a surprise, a ringlet, then more and marbled white, small skipper, meadow brown, small heath and even dark green fritillary. Although it was overcast it was warm enough for insects to be active, but not so warm that they were too flighty, this allowed a great chance to get really good views as they basked in an attempt to get warm.

Some of the butterflies were warm enough to get on with life.

The marbled white were especially numerous and lots of the females were egg-laying.

I noticed one small skipper below a pyramidal orchid flower spike, at first I thought it was sheltering, but it did not look right, then I realised that it was actually in the jaws of a crab spider, ambushed as it was trying to get warm, or maybe feeding. Luckily not all of them had fallen victim to predators.

We also saw silver-washed fritillary, but the most surprising butterfly seen was a purple hairstreak, picked up off the path, but which flew off before a picture could be taken. Although we never saw the sun we did see a common lizard, sitting out in the hope of catching a few rays. As we always do and despite unpromising conditions we had a great time and saw a lot of wildlife. Martin Down is a magical place to go and a reminder of what large parts of the southern chalk must once have been like.

 

30 Days Wild – Day 25

Day 25 and I was in Portsmouth at the Lakeside North Harbour site doing a public event for National Insect Week. Looking at the pictures I have posted during 30 Days Wild it would seem I have been more or less doing 30 Days of Insects, but as they form so much of our wildlife I will make no apologies for doing so. The other reason is that I only have one decent lens for my camera and that is a macro lens! You can find out more about National Insect week at http://www.nationalinsectweek.co.uk. It is run every two years by the Royal Entomological Society with the assistance of lots of other organisations including the Wildlife Trusts.

The Lakeside site lies just beside the A27 and is a large area of offices in several blocks, perhaps it does not sound that promising for wildlife? But think again, it is constructed on chalk which was dumped onto marshes left isolated north of the road, so far so disastrous for wildlife, but the habitat that has developed is chalk grassland with lots of flowers including thousands of orchids. There is also some wetland and scrub, in short a varied and generally nutrient poor landscape, with a wide range of species, something of a biodiversity hotspot! The management has been enlightened enough not to “garden” too much of it, although the corporate love of grass like a carpet, lollipop trees and gob-stopper bushes is evident in parts. Anyone who visits a corporate HQ or similar office cannot help but be struck by how much they really baulk at the intrusion of the natural world, few tolerate any native flora and fauna and obviously spend lots of money keeping the areas around their buildings that way. An odd approach when most would say they are efficient and environmentally aware.

As I said lakeside is actually a very good wildlife site and shows what can be done, in addition the more natural areas are very popular with the staff, many of whom will walk around the grounds in their lunch break. A “Green break” is something that I am sure is good for their wellbeing and probably afternoon productivity.

The weather was not the best, my plan to run a moth trap overnight had failed as the trap had not turned on and half the people booked onto the walk did not show up, so not the best of starts. However the insects did not let us down and we were joined by as many people who had not booked as were on the original list, so we actually had more participants than  expected. Highlights were six-spot burnet, both as larvae and adult, with this one posing on a pyramidal orchid for photos.

We also saw several species of hoverflies, two soldierflies, robberflies, damselflies, lots and lots of true bugs, beetles and even a few butterflies. The weather was against us though and just as we were coming to the end of the event we all had to run for shelter  as the heavens opened and the thunder and lightening swept in.

rain and lost of it!

In the afternoon I was back at Blashford, where the weather was much better, although I passed through some of the heaviest rain I have encountered in many years on the way. When you see the full force of a really torrential downpour like that it is interesting to imagine what the impact must be on creatures as small as insects, it must be significant.

Storms are local events so even if they could be devastating they should not impact whole populations. Spiders however are everywhere and the recent mass emergence of damselflies has given them more food that they can cope with, one web by the Centre pond contained three such victims. Shear numbers are what keep insects going, even if thousands die, enough can go on and each survivor can produce many offspring.

As I locked up it was pleasing to see that there were still lapwing chicks on view near the Tern hide and that at least two of the little ringed plover chicks have fledged. I also spotted that the female common scoter I found with the tufted duck flock on Thursday was still there diving for food out in the middle of the lake.

Monday Catch-up

Not much news from today, apart from tha fact that it was warm, dry and mostly sunny, so quite unusual for this summer! I was leading a walk this morning and the sun had brought out a few butterflies, including red admiral, painted lady, meadow brown and speckled wood, there were also 2 emperor dragonflies egg-laying in the Centre pond. The sun did allow me to get a few insect pictures and I post these along with some from Saturday, which never got posted.
