Autumn’s nibbled tresses

The weather certainly feels as though it is heading for autumn, although the recent (and current!) rainfall has certainly improved the look of our original dipping pond which with a tear in the liner had definitely suffered during the rather long hot dry spell.

Our dipping pond, looking much happier and healthier than it did a few weeks ago

Thankfully we have had the second pond to use for our dipping sessions and yesterday saw another four very happy family groups delving into its depths to see what they could catch.

The highlight for me this time were the few alderfly larvae we caught in the morning:

Whilst out by the pond we also had great views of a number of dragonflies, with a common darter perching close by on the boardwalk, a pair of common darters mating in the wheel position and resting on nearby vegetation, and in the afternoon a female southern hawker getting very close to us and egg lay into the grooves in the wooden boardwalk.

I have seen dragonflies egg laying straight into the water and pond vegetation many times before but hadn’t realised some species prefer to lay their eggs into wood on the pond margin and will happily use a newish boardwalk rather than an older rotting stick.

Whilst dipping a Common carder bee flew onto one of the children, who was not worried at all, but in brushing it off her leg it fell into the pond where she was so close to it. It was quickly rescued and relocated onto some of the flowering water mint to recover:

 

August is the time of year to look for the last of our flowering orchids, Autumn Lady’s-tresses, which can be found on grassland and heathland. Here it grows in places on the lichen heath, if it is given the chance!

It is a very delicate looking orchid with white individual flowers that spiral round the short stem. I have been on the lookout for them since the start of the month, when they first started popping up on social media, but had no success. Although they can be very hard to spot I put their absence in part down to the very dry spell we had over the spring and summer. Jim though did manage to spy a small group of them on the lichen heath and Bob, in checking for them again came to the conclusion the increasing numbers of rabbits on the reserve have in fact merrily munched their way through the ones that have flowered.

Not expecting much, I decided to have one last try this morning before the rain arrived and was rewarded with one flower, admittedly slightly past its best, in amongst a clump of I think St John’s Wort (I say I think as that was also going over) which clearly kept it safe from the rabbits. Nearby I also spied a second stem, with the flower bitten clean off:

If anyone would like to try and find some, I think Wilverly Plain in the forest will be a better place to look!

It is probably time for me to relocate everything from the Welcome Hut (a much nicer spot to work from even in the pouring rain!) back to the centre, so I will finish with a few photos taken a week or so go that I didn’t quite get round to sharing: a bee-wolf and another heather colletes bee enjoying the heather in bloom in the meadow and a solitary bee on the Inula hookeri outside the front of the Centre.

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.

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.

Gold spot, the photo definitely doesn’t do this moth justice

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.
