30 Days Wild – Day 23

A day off to receive a delivery and get work done on my car, so spent at or within walking distance of home. I had planned to do some gardening, but it was too hot to do anything very strenuous, so most of the time was spent insect watching. The mini-meadow is still looking great with field scabious and knapweed now taking over as key nectar sources.

There are lots more “bit-part players” as well like the lady’s bedstraw, which are not very showy but add variety and support other species.

The most obvious flowering plant now is the wild carrot, it attracts lots of species with an easy to land on flower head and a bit of easy food for a wide range of species.

With so many insects around at present it is unsurprising that there are predators, I came across my first robberfly in the garden this year.

I had thought that I would not get free to do very much, but as it happened all my ties were dealt with by lunchtime, so I went onto the Heath for a short time in the early afternoon. It was very hot, this is usually a place I go at dusk, so It was great to see it int he heat of the day. The area is a conifer plantation that has been partly cleared and the rest thinned. I really wants to be heath and everywhere there is enough light getting to the ground is now covered in heather. I was amazed by the huge numbers of sliver-studded blue everywhere, in areas only cleared last year and even under the thinner areas of pines. Although it is often said they spread only very slowly, perhaps just a few tens of metres per year, where they get a new opportunity they can evidently spread much faster than that. There were also lots of wasps of many species, none of which I could identify and fabulous bog flora such as bog asphodel and sundews.

The heat made photographing insects difficult as they were so active, but at least the longhorn beetles were a bit easier.

30 Days Wild – Day 17 – Butterflies and More

We have been doing butterfly transects at Blashford Lakes for some years now, I say “We”, what I really mean is that the volunteers have been doing them. I used to do transects myself on previous sites I have managed and thoroughly enjoyed doing them, an opportunity to go out on site for the main purpose of looking for wildlife, something I actually get to do rather rarely! In theory I have always been on the rota to help with the transects at Blashford, but as a stand-in, if someone else is unavailable. Well this week I have been called upon and as it was warm and reasonably sunny this afternoon I headed out.

It was not a classic butterfly day but I did see 26 butterflies of four species. Most notable were the five red admiral, I suspect they are new migrants as the weather is set fair for an arrival of migrants over the next day or so. Locally bred were meadow brown, common blue and speckled wood.

Whilst looking for butterflies it is inevitable that you will see other invertebrates, I saw six species of dragonflies and damselflies, several yellow-and-black longhorn beetle and lots of the larger summer hoverflies, especially Volucella bombylans and Volucella pellucens.

Not all of the invertebrates were adult, I found a vapourer caterpillar feeding in the open, something they can afford to do, as they are protected by a dense coat of hairs which most birds will avoid.

Some things I cannot identify, or at least not accurately, one such is this digger wasp, I am pretty sure it is one of them, but which one?

Some of the invertebrates were not insects at all, I came across a loose bit of bark on the ground and under it were several slugs, the familiar leopard slugLimax maximus.

This is the common native large slug in woods and gardens. However it is increasingly being overtaken in abundance by the green cellar slug, Limax maculatus. This is a species native to wood in the Caucasus area that was accidentally introduced some fifty years or so ago and is now spreading rapidly.

One plant that is oddly scarce at Blashford is honeysuckle, so I was pleased to see one of the few plants we do have growing well in magnificent, full flower.

Lastly a picture of a rare plant in Hampshire, but one that is quite common at Blashford, slender bird’s-foot trefoil, it is flowering abundantly just now.

Quiet a “Wild Day” considering I was stuck in the office wrestling with report writing for quiet a good part of the day and also out doing path clearing for part of the day.

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 3 – A Herd of Elephants

I was at Blashford Lakes Nature Reserve today after a couple of days off. We had a volunteer work party in the morning but before we started I checked through the moth trap, although the catch was quiet good there was nothing too surprising, although I was pleased to see my first peach blossom of the year, no picture though as it flew off. There were several hawk-moths including a group of three elephant hawk-moth on one egg box.

There were also a few species of prominents including a pale prominent, they all get their name from the small raised point on the folded wing, presumably an adaptation to break up their outline and make them look less like moths. For a moth, not looking like a moth is very useful as birds love to eat moths, so lots of moths either hide away or just try to look not like moths. The pale prominent does this rather well.

Our volunteer tasks were giving the outside of the Education Centre a was down and having a clear-out of the tool store, both much needed tasks, if not exactly conservation work. At least we should be able to find most of the tools and equipment now and the building does look a lot smarter for a wash.

I checked the hemlock water dropwort around the centre pond at lunchtime for visiting insects, the flowers are a very good nectar source. There were lots of hoverflies and a few beetles including a wasp beetle, a yellow-and-black longhorn beetle and a red-headed cardinal beetle.

What’s in My Meadow Today?

By the time I got home most of the meadow in my garden was in shade, but it was still making its presence felt. The grasses are flowering and their pollen is blowing in the wind as every hayfever sufferer will know. Grasses do not rely on insects to carry their pollen from one flower to another to achieve fertilisation, they just release huge clouds of pollen into the air to be carried to another flower. This saves on the need to produce nectar as an inducement to insects, but does mean that a lot of pollen has to be produced.

Many trees use the same method, resulting in allergic reactions for many in spring.  Pollen deposited in peat and similar wet habitats has allowed us to look back in time and work out what the dominant vegetation cover was in the distant past. It turns out that although there was rapid colonisation of the UK by tree after the end of the last Ice Age the nature of the cover changed over time. One tree now generally rare, the small-leaved lime, was abundant at one time and it turns out that elm have seen several rises and falls in abundance, perhaps indicating previous outbreaks of “Dutch” elm disease.

The tiny garden pond does not have many plants, but one it does have is lesser reedmace and it is now flowering and also sheds pollen into the wind, the pollen is produced by the male part of the plant, which here is the upper part of the flowering stem.
