After the weather of the last few weeks the forecast for the weekend was not good, as a result Ian and I decided to go looking for orchids. It was maybe a little early but we thought it was worth a chance, so we met at Portsdown Hill and made our way down the hill. As we left the cars a Whitethroat was singing in a dead bush behind the cars.
It was overcast with a brisk breeze, but we managed to find this Small Blue sitting on a leaf huddled down in the grass.
We walked along the bottom of the cliff and into the grassland where last June we had found both Lizard and Bee Orchid. It took some time searching through the grass and bracken and the search was looking quite fruitless until Ian found this Lizard Orchid spike.
It was a little surprising to see this Common Blue flying around amongst the grass.
A Five-spot Burnet moth nectaring on the buttercups.
As we started the climb back up to the top of the cliff we found this Small Blue, again, roosting on a grass stem.

Back at the cars we decided that with the weather it would not produce any butterflies elsewhere, and the orchids were would be after still had maybe a couple of weeks to go, so we headed for Titchfield.
After parking at Cliff Road we walked down to the new visitor centre where I renewed my subscription. We decided to try the east side as there had been reports of Willow Emerald Damselflies around the boardwalk.
We stopped off at the "Walkaway" Pond and searched the reeds and Lilypads. Ian then found this exuvia, the discarded skin of a Damselfly nymph. These are sometimes also call carapace.
We found several more empty skins, but then struck gold with one where the damselfly was just emerging.
Dragonflies and Damselflies undergo incomplete metamorphosis; unlike
other winged insects, such as butterflies, dragonflies do not have a pupal
stage and transition straight from a larva to an adult. This transition,
the final larval moult, takes place out of water. This metamorphosis is
triggered by day length and temperature, and is synchronised in some species,
such as Emperor Dragonfly.
The final-stage larvae sit in shallow water, near the
margins, for several days, getting ready for their final moult and starting to
breathe air. Most species leave the water during the morning, the larvae climb
up emergent vegetation, although some may walk several metres over dry land
before finding somewhere suitable to emerge. After finding a secure support,
they redistribute their body fluids, pushing the thorax, head, legs and wings
out of the larval skin. There is then a pause to allow their legs to harden
enough for the next stage, when the abdomen is withdrawn. The wings, and then
the abdomen, are expanded and start to harden. This process leaves behind the
cast skin or exuvia, and the whole process lasts between one hour (Damselflies)
to three hours (Dragonflies).
We decided to watch and see what happened.
Freeing itself from the exuvia.
Then edged away from the exuvia for the next stage.
Fluid was pumped into the veins on the wings, you can see the wings extending and firming up.
Extending the wings beyond the abdomen.
Then once the wings were complete the abdomen started to extend now beyond the wings.
Originally we thought this might be a Willow Emerald, but as the process went on we felt that maybe this was female Common Blue. This was the last image we took and it looks like one from the markings beginning to form on the thorax.
The whole process took just over an hour, a time in which we had lunch! We came back just before we left the reserve and the Damselfly had gone. It was amazing to watch regardless of the species.
A little further along the boardwalk towards the Knights Bank hide, we found some orchids. These were Southern Marsh Orchids, looking splendid amongst the emerging horse tails.
We headed back to the harbour where the drake Eider that has been around for a few months now. Today it was sitting on the mud, something you only see along the north east coast, so quite a privilege to get quite close.
The Mallard all came over to us thinking we had food and the Eider seemed interested too.
Eventually taking to the water and swimming towards us.
It did change its mind and turned and swam with the current out of the harbour.
We walked around to the west side and had some time in the Meon Shore Hide. There were the Avocets still with their two chicks and several more on some of the other islands. Common Tern could be seen nesting too. There was only one Black-tailed Godwit.
On the small island in front of the hide the Black-headed Gulls were either sitting on eggs or feeding chicks, this gull was sitting on the chicks and they came out from under the gull.
And food was regurgitated and fed to the chicks.
There was some Marsh Harrier activity around the scrape, but they did not come too close, the gulls and Avocet keeping them away.
The other point of interest over the scrape were the Swifts, at least half a dozen, maybe more were swooping over the scrape.
A day that was made interesting by the find of the emerging damselfly, whatever it was!
