From pond to meadow

At the beginning of June we re-started our Wildlife Tots sessions, discovering the weedy depths of the Blashford Pond.

Our morning session started with a rescue, with Isabelle fishing this Emperor dragonfly out of the pond. It was quite happy to be handled, or relieved to be rescued, so we were all able to take a really good look.

I then relocated it to a safer spot, where it could finish drying off. It was still there when we met the afternoon group, so they were able to take a look at it too before it flew off.

Newly emerged adult dragonflies are known as tenerals. They are weaker in flight and paler in colour. As the body and wings harden off they begin hunting for food, spending about a week feeding away from water and gradually acquiring their adult colouration. They are then ready to return to the pond to mate. 

It was a good day to look for dragonflies, we found lots of exuvia on the vegetation around the edge of the pond and found another newly emerged Emperor dragonfly along with a newly emerged Broad-bodied chaser.

From the pond itself we caught dragonfly and damselfly nymphs, newts and a caseless caddisfly nymph, amongst others: 

It was also nice to see the other insects enjoying the vegetation around the edge of the pond, like this honeybee, large red damselfly and figwort sawfly:

At the end of the day I was lucky enough to spot another dragonfly emerge, this time it was a Black-tailed skimmer:

So it was a very good day for dragonflies!

At the beginning of July we headed to the meadow. On the edge of the lichen heath we spotted this small tortoiseshell butterfly:

As we went in to the meadow we disturbed this grass snake, and we watched it slither up the hill to the birch trees at the top.

We then sat quietly and did a still hunt, looking closely at the miniature world of the meadow around us before using sweep nets to catch grasshoppers, spiders, beetles, true bugs and more.

We also saw a solitary bee, small skipper butterfly, ruby-tailed wasp and marmalade hoverfly:

My highlight from the meadow though was this solitary wasp, the Bee-wolf. The females prey on honeybees, paralysing them with a sting and carrying them back to their sandy burrow. Up to six paralysed honeybees are placed in each chamber within the burrow, then a single egg is laid and the chamber is sealed with sand. After hatching, the larva feed on the honeybees before spinning a cocoon to hibernate in through the winter and emerging the following spring.

Our Wildlife Tots group offers fun outdoor play and wildlife discovery activities for pre-school aged children and their parents or carers once a month, usually (but not always!) on the first Monday. After a break in August, we will be meeting again in September, and details will be available on the events page of our website soon.

Spring is definitely here. On Ibsley Water the wildfowl have made way for the noisy black-headed and Mediterranean gulls which can be heard calling noisily overhead. Although a few ducks remain, including goldeneye, shoveler, goosander and gadwall, the majority have now departed.

This afternoon a pair of redshank were feeding along the shoreline in front of Tern Hide whilst a pair of oystercatcher were on the island.

Black-tailed godwit numbers have decreased and a black swan seems to be favouring the north-western corner of the lake. Although I’m still waiting for my first swallow, sand martin numbers have increased hugely and watching them does not disappoint. I popped into Goosander Hide yesterday to see if any were investigating the sand martin bank and they most certainly are:

Although the hides remain closed and we have no plans to open them at present, it’s nice to know the martins are back and hopefully, if the next few months go to plan, it may be possible for visitors to catch the end of this year’s nesting season later on in the summer. We will be keeping our fingers crossed!

Reed buntings have been singing high from the willows on the edge of the main car park recently, and yesterday after leaving Goosander Hide I spotted this one sitting pretty in the top of a silver birch:

The highlight of yesterday’s walk (and something that definitely made working Easter Sunday worth it) was this sighting of one of the white-tailed eagles, high in the sky over Ibsley Water. They can cover such a huge area, you definitely need to be in the right place at the right time and have luck on your side, this was my first sighting of one of the (I’m assuming) Isle of Wight birds. Not the best photos, but they’re definitely good enough to tell what it is:

After getting mobbed by some gulls, which pushed it closer to where I was standing, it flew in the direction of Ibsley Common and the forest beyond.

Staying on the northern side of the reserve, the warmer weather has bought out the reptiles, with both adder and grass snake enjoying the sunshine. I’m still waiting for a grass snake photo opportunity, the adders have been more obliging:

Adder

Although there is some just outside the Education Centre, the edges of the footpaths past Lapwing Hide and the boardwalk are good places to keep an eye out for colt’s-foot. Local names of this flower include foal’s foot and ass’ foot, clatterclogs, horse hoof and son afore the father, with the latter name referring to the fact that the flowers appear before the leaves. 

Colt’s-foot

Wherever you walk at the moment it’s impossible not to hear the unmistakeable call of the chiffchaff, and with their numbers swelling on the reserve their call is turning into the back-drop of spring, along with Cetti’s warbler and blackcap.

I have managed a half-decent photo of a blackcap but will keep trying, as Steve Farmer very kindly shared his beautiful images – thank you Steve!

As well as the spring birds, it’s been lovey to see so many insects, with brimstone, red admiral, small tortoiseshell, speckled wood and peacock all on the wing. The brimstones have even posed for photographs:

The bees are also buzzing, with honeybees, bumblebees including the common carder bee and a number of different solitary bees active.

I’ve seen both tawny and ashy mining bees as well as this little one:

Solitary bee

Smaller and less striking or noticable than the vibrant female, I think it could be a male tawny mining bee, but am not completely sure.

There are also lots of dark-edged bee-flies about. This bee mimic has a long straight proboscis that it uses to feed on spring flowers like primroses and violets. Their larvae are nest parasites of ground-nesting and solitary bees, feeding on the bee grubs. The female bee-fly flicks her eggs towards the entrance holes of solitary bee nests to allow the larvae to hatch in the right place. Once a bee-fly egg hatches, the larva crawls into the underground nest cell of a host bee where, once large enough, it attaches itself and starts to suck out the body fluids of the host species…

Elsewhere in the woodland the wild daffodils are fading and making way for carpets of lesser celandine, with ground ivy and dog violets adding purple to the bright yellow. As Jim mentioned, the tiny and easily overlooked moschatel, or town-hall clock, is also flowering, although you have to look closely to see it!

Although the past couple of nights have been cold, resulting in a slightly less exciting catch in the moth trap, moth species have been picking up and there has at times been a very nice variety to look at and photograph. I think the oak beauty may be my favourite, so far…

So there is plenty to see and hear on the reserve at present, and as well as making the most of what spring has to offer it has been really nice to see some of our regular visitors and volunteers who live a little further afield venturing back to enjoy the insect and bird life and a walk in a slightly different location. With pond dipping events planned and hopefully an onsite Young Naturalists meeting at the end of the month, it feels as though things may be going in the right direction…

So many insects, and a baby toad

Last Thursday I was passing the marjoram in the planter outside the front of the Education Centre when I noticed a bee I had not seen before. It was quite large and very striking, with a strong pattern on the underside of the abdomen. I managed to take a couple of photos and after a bit of research decided it was one of the sharp-tailed bees and probably the large sharped-tail bee, Coelioxys conoidea. Since Thursday it has been a fairly regular visitor to the marjoram and has been seen and photographed by a number of visitors, and Bob also confirmed it was a large sharp-tailed bee.

Large sharp-tailed bee, Coelioxys conoidea

Sharp-tailed bees are cuckoo bees, laying their eggs in the nests of megachile (leaf-cutter bees) or anthophora (flower bees) species. Only the females have the pointed abdomen which is used to cut a slit in the partition of the host’s cell so the egg can be placed inside. The coelioxys species hatches first, with the grub devouring the host egg and its food source.

This particular species favours the coast leaf-cutter bee, Megachile maritima. As the name suggests, they have a strong liking for the coast but can be found inland in areas of the New Forest. On Monday I noticed a leaf-cutter bee enjoying the Inula hookeri which is now flowering outside the Centre. The plant has large flower heads which the bee was meticulously working its way round before flying off to the next, so I was able to watch it for some time. Although not completely sure it was a coast leaf-cutter bee, they must be onsite somewhere if the large sharp-tailed bees are present.

Bob has been on a mission to fill the planters with plants that are good for pollinators but not liked by the deer, who have taken quite a liking to a number of them. The Inula hookeri however is not to their taste and the large yellow flowers are providing a brilliant nectar source for insects and its been great to watch the butterflies and bees visiting.

Whilst watching the brimstone enjoying the flowers I noticed a bright green and very smart leafhopper, Cicadella viridis:

There are also still blue mason bees around, they quickly made use of the new bee block Bob added in to the end of the planter and can often be seen resting on the planter itself.

On Sunday I popped to the meadow in the hope of seeing another bee I haven’t seen before which this time favours heather. The heather is now in bloom, but seeing a heather colletes bee proved harder, or at least seeing one still for long enough to get a good look was quite a challenge. They whizz around even faster than the green-eyed flower bees do.

Eventually one settled long enough for me to get a look and half decent photo:

Whilst watching the bees whizzing around I noticed a bee-wolf fly straight towards me clutching a honeybee. It landed by my feet, I had obviously been right next to its burrow and had taken it slightly by surprise, but after sorting itself and its prey out it flew to its burrow and disappeared. It was fascinating to watch.

The light trap has revealed more than just moths over the past week. Last week we had a couple of visits form a rather large longhorn beetle, the tanner beetle, which is also attracted to light. They are a large beetle with a body length of 18-45mm and are broader than the other longhorn species.

Credit for this photo goes to regular visitor John 6×4, as I have been regularly working from the Welcome Hut since our wifi was improved and he bought the beetle over, on a log, for me to photograph. We were also able to show it to a passing family who were rather impressed!

Another beetle that found its way into the light trap was this species of dor beetle. It was very active so was a bit harder to photograph:

On the moth front the two traps have contained a good variety, although many are quick to fly first thing where it has been so warm. Highlights have included bloodvein, coxcomb prominent, light crimson underwing, pebble hook-tip and a stunning gold spot.

We have also received some great photos this week from visitors. Jon Mitchell visited on Sunday for the first time since lockdown and was able to see and photograph both the large sharp-tailed bee and the heather colletes bee, along with damselflies, a gatekeeper and a couple of dragonfly exuvia by the pond. The second dragonfly nymph clearly thought the first had picked a good spot when it crawled out of the pond.

Sam has visited a number of times recently and asked his mum to share photos she took of the toadlet and alder beetle larvae he found whilst exploring here on his last two visits:

We do enjoy seeing photos taken by visitors whilst out and about on the reserve so if anyone else has anything to share please email it to BlashfordLakes@hiwwt.org, along with whether or not you are happy for us to share it wider via the blog.

Thank you very much to Jon and Sam for sharing your photos with us.
