30 Days Wild – Day 14 – Garden Safari

I spent almost all of the day in the garden, working in bursts until I got too hot, then just sitting back and watching. There was a lot to see, twice groups of crossbill flew over, these birds breed very early in the year and then the families set out to look for ripening cones from which to prize the seeds. In some years, when the breeding season has been good but the cone crop is poor, birds will fly very long distances, hundreds or even thousands of miles. These are known as irruptions and are characteristic of species that exploit locally abundant, but unreliable food sources.

The main interest was the insects though, the pond continues to draw in dragonflies and this fine male broad-bodied chaser spent most of the day nearby.

Whilst looking in the flower border at something else this recently emerged emperor dragonfly was spotted, not by me, although I was looking at something about 15cm away!

As it was so close I got a few closer shots of the head and eyes. They have almost all-round vision with thousands of tiny facets to the eyes, which also have different coloured zones.

It was not just dragonflies though, there were meadow browns in the mini-meadow and a red admiral on privet flowers, a small white attempting to lay eggs on the cabbages was less welcome though. The wild carrot is now coming into bloom and attracts quite a few species, including a second garden record of the mottled bee-fly, first seen a few days ago.

Beetle included a Welsh chafer on a pink bistort flowerhead.

Lots of bees mostly evaded my camera, but I did get this male leaf-cutter bee resting on the side of the bee hotel, I confess I totally failed to identify this and had to be put onto the right course, I still find bees difficult!

However prize of the day goes to an especially brilliant bug. I was working near the house when I was called to see “A red and black shieldbug” an exciting prospect as there is a recently colonising species spreading at present. However I was in the middle of  a task so had to wait a couple of minutes before going over, luckily the bug was still there and it was an ornate shieldbug.

A species which is slowly colonising the south coast, something to look out for on plants of the cabbage family, this one was on rocket in our salad patch. Unlike some other species people ask us to look out for this one is pretty much unmistakable and really stands out, although it does come in various colour forms, so they don’t all look like this one.

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 16 – Dealing with Uncertainty

After writing yesterday’s blog I was out at dusk surveying nightjar again. I did find some nightjar, I heard at least four churring males, but the highlights were actually a roding woodcock and drumming snipe. The churring of nightjar is an extraordinary sound, much more reminiscent of machinery than a bird. Woodcock make a strange squeaking call as they fly around their territory and, if they fly right overhead you will also hear a short croak between the toy-like squeaking. Snipe are closely related to woodcock and also fly around at night on display flights, they make a weird sound called “drumming”, this is not a call but a noise made by the bird diving at speed so that the air causes the outer tail-fathers to vibrate. A walk on a New Forest heath at night is a fabulous experience filled with strange sounds.

Day 16 started with a look at the moth trap, there were 2 privet hawk-moth, but the only new species for the year was an uncertain, or was it? It might have been a rustic, because these two species cannot reliably be distinguished and are best recorded as an aggregate.

perhaps an uncertain and not certainly a rustic

What’s in My Meadow Today?

There are several dandelion like yellow flowers in my meadow, but a lot of them are not dandelion. The Jack-go-to-bed-at-noon is one as are the hawk’s-beards. The smallest is smooth hawk’s-beard.

They are very attractive to nectaring bees and these small bees, which I have not identified so far, like them all and often move from the smooth hawk’s-beard to the other common species, beaked hawk’s-beard.

Looking into the meadow is always worth a second and a third look. As though to confirm its status as a meadow I spotted two meadow bug Leptopterna dolbrata.

I think these are a pair, although the females typically have short wings and both of these are fully winged. I also found a brilliant green beetle on the wild carrot flower head, it was a rose chafer. This was at about five in the afternoon on Day 16, as I write this now, at just after seven in the morning on Day 17, looking out of the window I can see the beetle still on the same flower head.

Chalk downland extravaganza!

On Sunday twelve Young Naturalists joined us for a trip to Martin Down National Nature Reserve, one of the largest areas of uninterrupted chalk downland in Britain. Jointly owned and managed by Natural England and Hampshire Country Council, the reserve is home to a fantastic variety of plants and animals associated with chalk downland and scrub habitats.

Regular readers of the blog will know that part of Martin Down National Nature Reserve, Kitts Grave, belongs to Hampshire & Isle of Wight Wildlife Trust. This site is managed as part of the wider reserve by Natural England, but our volunteers do a couple of tasks there each winter – we did not visit this part of the reserve so as to avoid a busy road crossing and the car park height barrier, parking instead at the end of Sillens Lane and exploring the Down between here and the Second World War rifle range.

Martin Down

The weather was in our favour and we got off to a great start, spotting brown hare in a field close to where we had parked the minibus. We headed off in the direction of the rifle range, keeping our eyes peeled for butterflies and listening out for the distinctive purring of turtle dove. This stretch kept us busy with our cameras and binoculars as we saw yellowhammer, skylark, red-legged partridge, jackdaw and chiff chaff.

The butterflies also didn’t disappoint, with specked wood, common blue and large skipper settling close by for photos. We also spotted a red and black froghopper and a fabulous caterpillar, later identified as that of a drinker moth.

As we left the edge of the tree line and headed into more open downland, we saw small blue, orange-tip, small heath, brimstone, large white and Adonis blue butterflies, along with a cinnabar moth. We also spotted a number of stunning golden bloomed grey longhorn beetles, with their fantastic long and stripy antennae.

The butterfly highlight of the day though was possibly this beautiful Marsh fritillary, which was in no hurry to fly away:

Geoff took a photo of this caterpillar, which we think is that of a six-spot burnet moth.

We also stumbled across lots of tent caterpillars, so grouped because of their ability to build conspicuous silk tents in the branches of host trees. They are sociable, with many grouping together in one spot and we believe most of those we saw are larvae of the small eggar moth – the second photo may show a different species or an older instar, I’m not completely sure!

We also scoured the tops of small trees and bushes in the hope of spotting a Corn bunting amongst all the signing skylarks, a bird I’d been hoping to see! We were in luck, watching one for some time before it flew off to perch further away on another bush.

We paused for lunch at the rifle range, an excellent spot as it turned out as whilst sat on the top we watched a female cuckoo fly from bush to bush below us, sitting on the top of one for a few moments before flying back into the scrub and out of sight.

We then followed the Neolithic Bokerley Ditch which snakes along the western edge of Martin Down, defining the Dorset and Hampshire border. Possibly built as a boundary in the Iron Age, it was fortified in the 5th or 6th centuries AD against invading Saxons. We were now in search of orchids, spotting plenty of common spotted orchids and finding the beautiful burnt tip orchids.

Orchid hunting

The other wild flowers did not disappoint either and we identified yellow rattle, kidney vetch, horseshoe vetch, meadowsweet and wild or yellow mignonette amongst others. We also saw and heard stonechat, more yellowhammer, a roe doe and two brown argus butterflies.

We decided we had just enough energy and time left for one last slope in the sunshine so headed uphill, in search of a greater butterfly orchid. At the top of the slope we found these along with fragrant orchid and also spotted a five spot burnet moth.

It was then time to head back to the minibus before the showers started and we almost made it! We had unfortunately run out of time to linger for long by any of the scrub for the sound of turtle doves and the rain shower although very refreshing began to get heavier, but Geoff who was walking at the back of the group did manage to pick out their distinctive call.

We had a brilliant day, it was definitely hotter and sunnier than we had been expecting which bought out a great variety of butterflies including Adonis blue, brown argus and the beautiful marsh fritillary. We also had great views of brown hare, corn bunting, yellowhammer and cuckoo. Martin Down is a brilliant site for downland species and definitely worth a visit on a sunny day!

Back at Blashford, the two oystercatcher chicks were again showing nicely in front of Tern Hide with both adult birds also present and continuing to be very attentive. The light trap has been revealing more moth species now the nights are warmer, with highlights on Sunday including a chocolate-tip (sadly no photo as my camera seems to have momentarily malfunctioned!) and scorched wing and yesterday we had lots of light emeralds and a lovely privet hawk-moth.

Our Young Naturalists group is supported by the Cameron Bespolka Trust. Thank you to volunteers Nigel, Geoff, Emily, Kate and Roma for your help on Sunday!

A Trip To Kitt’s

At last the weather has turned to spring and, although I should perhaps have been working in my garden, I took the opportunity to go up to Kitt’s Grave. I have never really had a look round there at this time of year, like most people I go up to Martin Down in the summer to see the butterflies. The opening up of the habitat on Kitt’s grave has continued this winter and it is beginning to look more like grassland with scrub rather than scrubland with trees.

The area above should develop into grassland over the next couple of seasons and if we are able to graze it as well it should stay that way, providing a lot more habitat for the plants and insects the site is so famous for. There will still be large blocks of dense scrub, valuable as shelter and for nesting turtle dove and other birds.

We did not see a lot of wildlife, several bullfinch were nice and the sun had brought out a few common lizard.

We also found a blood-nosed beetle, I confess that until I looked it up when I got home I had not appreciated that these can be found as adults at any time of the year.

They the largest species of a group known as “Leaf-beetles” and eat bedstraws growing in open habitats, so it is easy to see why downland is a favourite area to find them in. They have particularly wonderful feet and a very deliberate way of walking. The elytra are fused along the midline so unlike most beetles they cannot fly. The elytra are the two halves of the “back” and are actually modified fore-wings, the wings other beetles use to fly with are the other of their two pairs.

Many Eyes

I was over at Blashford this afternoon, although I was mostly confined to the office, luckily there were people who were not. There was a school group in and they made a couple of good finds. Whilst pond dipping they found a downy emerald dragonfly that had fallen back into the water, they rescued it and put it to dry on plants beside the pond.

I took the opportunity to get a few really close up shots as well, like this head-shot, it really is “downy” and “emerald”!

The dragonfly was not their only find though, they also found a very fine ground beetle, Carabus granulatus.

Not only is it also a rather splendid metallic sheened insect but it also has wonderful sculpturing on the elytra (wing cases).

As I was outside to take the pictures and the sun was out I had a quick look around the pond area and found two Rhingia campestris, a common hoverfly with and extraordinary long “snout”.

The female was very fat, presumably full of eggs.

Birds reported today were at least 10 swift over Ibsley Water, 3 common sandpiper, over 30 common tern and 2 Arctic tern also on Ibsley Water.
