30 Days Wild – Day 8

A morning walk at Fishlake Meadows with a Wildlife Trust group got the day off to a good start, although rather windy and eventually curtailed by rain. We were looking at insects and flowers in Ashley Meadow, a part of the reserve that is not normally open to visitors. It has lush wet meadow and fen vegetation including a good population of southern marsh orchid.

Insects were rather few, but we did find larvae of the fleabane tortoise beetle, a few snail-killing flies and hoverflies, before the rain put an end to things. The canal was a little higher after the rain but the yellow water lily were keeping their heads above water well enough.

Back at home by lunchtime today as the walk was a morning only event, th esun came out and a quick check soon found the silver-studded blue just about a metre from where I left it yesterday.

Something hopped onto the grass close by, a grasshopper nymph, the first I have seen in the garden this year, although it is already well grown, so I must have just missed it until now.

As it was World Oceans Day I thought I should go down to the sea, so made a quick trip to Lepe. A steady passage of common tern carrying fish suggests that breeding to the west is going well, so far, I just hope the storm has not flooded out too many nests.

Even though it is June the last twenty-four hours have been decidedly wild, in not such a good way, with unseasonable wind and a fair bit of rain.

A different sort of wild tomorrow as it is the Wood Fair at Roydon Woods and I will be there doing some mini-beats walks and generally enjoying this fabulous site and of course all the exhibits and stalls.

30 Days Wild – Day 7 – Blue out of the Grey

Not perhaps the best day to be wild, but after a long dry spell much of our wildlife will be welcoming the rain. Birds like song thrush and blackbird need worms to rear their young. The snails will welcome some rain as it will deflect the thrush from eating them and enable them to get out and eat my vegetable plants!

However it did not rain all day and in a brief sunny interlude I found a blue butterfly in my mini-meadow and not just any blue, but a male silver-studded blue.

To record an odd individual might not seem a great surprise, but I have seen them every year and sometimes several individuals of both sexes. This is a heathland species, renowned for having colonies that are very localised. In fact research has shown that most travel no more than 50m from where they hatch and many only up to 20m. Their flight is quite weak and usually low to the ground, in short they don’t get out much!

When I see them in the garden they are in the mini-meadow, a tiny grassland about 4m x 5m, otherwise the garden has a small lawn and flower borders with a small vegetable patch, no heath at all. What is more I live in the midst of ordinary suburban gardens, across two roads there is the New Forest, but even then it is short turf and conifer plantation. The nearest silver-studded blue colony is relatively close at 750m away, but it seems that this is something like 15 times as far as even an fairly intrepid silver-studded blue would go in a lifetime. To cover this distance would also involve not crossing open heath, but a large conifer plantation, two roads with hedges and a further line of trees. Even stranger the butterflies I see are, like today’s, not well travelled, worn, veterans but freshly emerged and pristine.

Silver-studded blue have remarkable lifestyles, their association with ants is only matched by the large blue. The newly hatched larvae are taken into the nests of one of two species of black ant and only venture out at night to feed on a variety of plants, but on heaths, usually heather or gorse seedlings. The caterpillars secrete a sweet substance beloved by ants, in fact it seems they suffer when it is not removed by ants.

The mystery of why I see them regularly in my garden remains, maybe they do breed in my meadow, but if so they are feeding on bird’s foot trefoil, something the heathland variety does not usually do, although they do so in limestone areas such as on the Great Ormes Head. It would also need there to be the right ants present, something I cannot confirm and it would be in a very atypical habitat, so seems very unlikely.

Settling before the next rain shower.

If anyone can shed any light on this mystery I would be delighted to hear, I am at a loss to explain why they appear so often so far from their nearest colony.

30 Days Wild – Day 29 – One More Time Out with the Blues

Just two days to go before another 30 Days are over. I spent part of Day 29 in my garden mostly looking at the meadow.

What’s in My Meadow Today?

There continue to be a good few small skipper and today also one large skipper, although in the heat it was so active that, try as I might, I could not get a picture of it. The hot weather suits most insects very well, allowing them to be more active for longer periods of the day. This may well mean that many species will be around for a shorter period than we are used to as they will have managed to fulfil their destiny and breed successfully in less time than usual. So I anticipate that lots of butterflies will be recorded in high numbers but for a short season if this weather continues.

Many people will know the common chafer beetle, sometimes called a “May bug” which flies mainly in May, but the smaller summer chafer is less well known, although still common. It seems to be having a good season as I am seeing more than I can remember this year. I got a picture of one on top of a wild carrot flower head.

I have featured a number of species of bee in this blog but honey-bee does not often get  a look in. The honey-bee Apis mellifera also known as the western honey-bee is our familiar bee species for most people. Its population in the UK is probably dependent upon domestic, artificial hive based colonies and it is speculated that it arrived here with humans at some time in the distant past. That said the honey-bees in more northern areas are darker and better able to maintain colonies in cooler conditions and it has been suggested these are native populations, they certainly seem to be genetically distinct from the more familiar paler bees found in southern England. Although most honey-bees do live in colonies in man made hives wild colonies are not unusual and there was a colony in a large Turkey oak at Blashford Lakes for several years, although it now seems to have been abandoned.

Although I did get out to take a look in the meadow most of the day was taken up with domestic activities. So as the evening was fine I took the chance to go out onto the nearby Forest to see the silver-studded blue once more. There were many groups roosting in the heather, often ten or more together and probably 80 or more roosting in no more than about 0.3ha.

Just one more post to go in the “30 Days”.

30 Days Wild – Day 22 – True Love

It seems we are having a very odd year, after a winter with some wintry weather we now have a summer with summery weather. I was late into Blashford as I had to attend a meeting off-site in the morning,  the moth catch was somewhat reduced after a rather cool night but did include a very fresh true lover’s knot. The name derives from the complex pattern, the name “true lover’s knot” has been associated with many actual knots, perhaps most often with one comprising two circular but interlocking knots that can move but not be pulled apart.

The moth is common and although a heathland species feeding on heathers, will wander widely so is often caught well away from this habitat, they probably also feed on heathers in gardens.

I spent much of the afternoon mowing paths, a rather thankless task, as soon as I cut the strip beside the path the taller vegetation behind tends to fall, resulting in a path that is barely more passable than before.

Locking up at the end of the day I came across a pair of spiders, looking somewhat “loved-up”. I don’t think this species is one where the male is at great risk, but it probably still pays to go carefully when your partner is much larger and a fierce predator with a mean set of fangs! (or perhaps long-jaws).

Mating in spiders is achieved by the male passing a sperm packet, using his modified pedipalps and I think this maybe what is happening in this picture.

It was still very sunny and warm when I arrived home and took a look in the garden.

What’s in My Meadow Today?

The grass is really drying out now and flowering of many plants is accelerating. The knapweed is well out now, having gone from nothing to loads of flowers in just two or three days.

Common knapweed is actually rather infrequent in true meadows, at least in southern England  as they would get cut before it goes to seed, it is more frequent in rough pasture or roadsides that are not excessively cut. It is a very good nectar source for lots of insects and so a couple of plants are a must for me.

It was a very fine evening and I realised I had not yet gone to look for the roosting silver-studded blue on the heath over the road form my house. These butterflies form small colonies usually on damp heathland and will roost in groups, typically on a slight slope that gets the last rays of the sun each evening. They make great subjects for photography, although the low light levels by this time of the day are always an issue.

The low light can offer the option of taking either with the light, as the top picture, or against, as in the lower.

Although the site is officially “wet heath” it is now bone dry and lots of the plants that should be surrounded by spongy bog are high and dry, which makes them much easier to photograph without getting wet knees. There were several bog asphodel plants in flower.

With the sun having set we were heading back when a cotton grass head standing out pure white in the gloom caught our eyes, in a typical year walking to a cotton grass plant could mean being up to your knees in a bog.

Going out on the heath on a fine summer’s evening is magical and certainly something everyone should do if they can, ideally carry on well after sunset and go and listen for nightjar, woodcock and snipe, what could be better! Britain is home to a large part of the European lowland heath, valley mire and a lot of it’s upland counterpart too come to that, so it is a very British experience.

 

30 Days Wild – Day 15 – Forest Visitors

I had most of the day off today and everything I have for the blog today comes under the  heading of……

What’s in My Meadow Today?

At first there did not seem to be much in the garden today, then I saw a dragonfly, at first I could not get to the right angle to see it through the grass, so I was not sure what is was. Eventually I could see it was a keeled skimmer, a species characteristic of the small boggy streams of the New Forest. When they first emerge dragonflies move away from water to feed up and mature. Once they are ready to mate they will return, where males will hold temporary territories and try to attract visiting females.

I have seen this species in the garden before in previous years,but this was my first this year.

Looking around a bit more I saw a blue butterfly, looking very fresh I thought it was unlikely to be a common blue, as these have been out for some time now and sure enough it was a silver-studded blue.

These wander from the heaths of the New Forest, and occasionally we see several in the garden, but this was my first this year. The Forest is probably the best area in the whole country for these butterflies which are heathland specialists, their caterpillars feeding on heathers. Where they occur is not as simple as where their foodplant is though, the heather has to be quite short and they also need the right species of ant to be present. The larvae actually live in the nests of black ants during the day, only coming out at night to feed, apparently being protected by the ants. The adults when they hatch out of the pupa continue to get protection form ants as their wings harden, droplets left on the body as they hatch seem to attract the ants. Remarkable and very beautiful little butterflies and a joy to have visit the meadow.

I have included several references to wild carrot previously in this blog, one of the  reasons I have it in the meadow is that it is an attractive nectar source, especially for hoverflies. looking a the largest plant in the meadow I noticed a hoverfly feeding with others hovering above it. The feeding fly was a female and the others were males engaged in a competitive hovering, hoping to impress her with their skills and so their fitness as a partner.

They are one of the dronefly species, Eristalis nemorum (Thanks Russ). Although the picture was taken at over 1/1000 sec the wings of the hovering males are still a blur.

My back garden meadow may not be large but if I look closely there is a lot going on in it.

30 Days Wild – Day 20: Over Heated

Tuesday is one of our volunteer days at Blashford, but it was not a day for heavy work in the sun. Luckily we needed to do a second sweep along the Dockens Water to remove Himalayan balsam plants that had either not germinated last time, or that we had missed. We found only about a couple of hundred plants, testament to the work we have done reducing it over the years. Along the way we saw a few common frog and good numbers of beautiful demoiselle.

I retreated into the office in the afternoon, where at least it was a little cooler, until it was time to lock up.

There was a little excitement at locking up time as I found a person paddling an inflatable boat on Ivy Lake. We know the damage this can do, some years ago two canoeists were found on the lake and this resulted in many of the tern chick jumping off the rafts in panic and several were lost. Luckily the chicks are about a week too small to jump off so they remained, although the adults were less than happy. It turned out the boatman was an angler, although not fishing.  He had a large bucket of bait and was looking for fish. It is a curious thing that anglers are very difficult to persuade that there is anything wrong with trespassing like this, they know that the water is not fished and private. When asked it turned out the boat had not been cleaned before use and he did not know where it had been last time out. The danger to inland waters and especially fisheries, of disease and alien species being moved about on wet gear seemed to have passed him by entirely. Anglers even had a euphemism for illegal entry and fish theft, they know it as “guesting” and it seems to be an accepted part of the “sport”. Small wonder that invasive aliens species and fish diseases get so easily moved around.

Once it cooled down a bit in the evening we went out for a walk on the edge of the New Forest. In some of the dried out puddles I came across a lot of coral necklace, a small plant typical of these locations and a bit of a New Forest speciality.

The main reason for the visit was to see silver-studded blue butterflies and I was not disappointed.

Along the way we also found a small heath and a freshly emerged common emerald damselfly, I am not sure I have seen one at this stage before and it was a very different colour from the mature adult.

The usually wet areas are very dry, so some species usually growing in wet bog are now high and dry, one example of this was a group of oblong-leaved sundew plants growing by the dry path.

Sundews are carnivorous plants catching insects on the sticky globules on the leaves.

30 Days Wild – Day 22

Lots of wildlife today, mostly after work. The sun was shining when I got home and int he garden I spotted the tell tale darting form of a hummingbird hawk moth. These are so difficult to photograph, but I did get one distant shot of this my first “Hummer” of the summer.

I am lucky to live close enough New Forest to be able to get out onto the heath after supper and before it gets dark. It was a perfect evening, although with rumbles of thunder not too far away, so we went out in search of silver-studded blue butterflies, one of the delights of summer and we found some getting ready to roost.

We also found various other insects settling down for the night, including a male keeled skimmer dragonfly deep in the heather.

One of the most obvious things we saw out on the heath were water droplet bejewelled spider’s webs. I think it was just moisture from the air that had gathered on the fine webs, it was very humid. The result was webs with huge amounts of water scatter all over them, this did not seem to be inhibiting the spiders which were still lurking in their tunnels and darting out to investigate movements on their web.
