Hi Trevor, good luck with your trip to Norfolk.
Hi Bugboy, I have seen a few posted on Twitter but not that many considering it is such an iconic species.
Norfolk June 10th to 14th – Swallowtails.
Over the past few years we have got into the habit of going away for a few days a number of times during the year in order to spend a bit of time exploring an area and hopefully see some species that we don't get around the midlands. I usually do some some thinking about where to go during the winter months and with me having to book time off work in advance, after doing some research on flight times of whatever species we hope to see, I take a bit of a flyer on the timing of our breaks.
Whilst thinking about targets for this year I had realised that I had only seen Swallowtails once before and that was now six years ago on a family holiday to Norfolk, when I had seen a couple at Strumpshaw Fen and just managed a couple of ropey record photos. We decided therefore that our first break this year would be to Norfolk and after looking at Swallowtail flight periods over the past few years decided on four days beginning 10th June. With a B&B booked it was with some trepidation that we watched the winter drag on into a late start to the season and then May arrived with some unseasonably hot spells that seemed to bring on some early emergences. I saw the first Swallowtails were being reported from the middle of May and also read comments to the effect that the warm weather was leading to some shortened flight periods for some species as they burnt themselves out in the heat.
Last Sunday (June 10th) we set off for Norfolk with me feeling fairly confident that there would still be some Swallowtails flying but also knowing that they had been flying for some weeks I was wondering what condition I would find them in.
We had started out at 9.30am and with our check in time at the B&B being the fairly standard 4.00pm we had plenty of time in hand for a stop off at Strumpshaw Fen where we arrived just after 1.00pm. Apparently a Swallowtail had been hanging around the flower beds by the visitor centre all morning ('You should have been here an hour ago....blah, blah, blah'.) but with no sight of it on our arrival we decided to have a wander around the paths. We wandered about for an hour or so and saw a couple of Swallowtails flying across the reed beds and had a close encounter with one which flew right past us on the path. Jane then said she would go back to the reception and sit in the hide whilst I had a bit more of a wander around. I went off down the track to the doctors garden where I found a large group of people by the flowers beds, some of who had apparently been there some time and mentioned that a couple had been seen earlier in the morning ('You should have been here this morning...blah, blah, blah'). After a brief conversation I decided to leave them to it, and carry on to where you re-enter the reserve over the railway track and was just approaching the gate when I spotted a Swallowtail fly off the reserve and towards a small rise on some rough ground a little further back. I decided to wander up this rise and found it covered with yellow flowers which looked like small dandelions (I am not that good with wild flowers – hawks-beard maybe?). I believe this is probably the area that I have seen mentioned in a number of reports from Strumpshaw in the past.. Anyway, My attention was soon drawn to what I presume was the same Swallowtail that I had seen fly in this direction as it flitted from flower to flower to feed. I must have watched this one individual for over15 minutes and took loads of quick shots as it balanced at the flowers with much flapping of its wings to steady itself. In the end I managed to get a number of decent photos of this one individual before it flew off back towards the fen.

I was well chuffed with this encounter, especially as it was an individual in good condition and if I didn't see another Swallowtail over the next few days I had already achieved my main target. Anything else now would be a bonus.
I then carried on to complete the circuit around the paths and had a couple more flypasts before arriving at the wet meadow area where another large group of people were taking photos of a couple of Swallowtails that were flitting between the many plants of ragged robin that grow there. These were much more difficult to get a decent photo of as the plants were mostly down amongst the grass and the thin stems would bend even lower when the Swallowtails settled on them which along with their almost constant wing fluttering meant that getting a half decent photo was a challenge.

I then went back to meet up with Jane and we then carried on for the further half hour drive to our B&B up by Hickling.
The next morning, after a good breakfast we had decided to pay a visit to Hickling Broad which was just a few minutes drive away. We arrived at the car park by the visitor centre at just after 9.30am and after paying the entrance fee and having a chat with one of the wardens, went for a walk around the paths. We spent the next three hours here walking the paths and visiting the hides and saw various birds including Marsh Harriers and heard a Bittern 'booming', plus loads of various Dragonflies. We also saw maybe five different Swallowtails at different points around the reserve. It seemed like more but I am sure that some were repeat sightings so I only counted those that were seen in different parts of the reserve. The morning had become very warm with the sun shining from an almost cloudless blue sky and all our Swallowtail sighting here were flypasts and although a couple of them came very close we didn't see any of them settle.
After going back to the visitor centre and seeing my first Meadow Brown of the year whilst sitting at one of the picnic tables and having a coffee, we drove around to Potter Heigham church where there is room to park a few cars and you can follow a footpath that goes across a field and through a wood to pick up the Weavers Way, a section of which passes along the southern side of Hickling Broad. Jane was tired after walking around the reserve in the morning and elected to stay at the car and read her kindle whilst I went to check out the paths. Coming out of the wood onto the Weavers Way I tuned left and walked along for about 15 minutes before coming to a stretch with a few ragged robin plants growing amongst the grass by the side of the path. Here I spotted a Swallowtail and managed to get a couple of shots before it flew off across the reed beds, although like yesterday in the wet meadow at Stumpshaw, it was difficult to get a photo without grass stems all over the place.

I then retraced my steps and walked along the path in the other direction for a similar amount of time and saw another 3 or 4 Swallowtails flying across the reed beds. Like earlier it seemed like a few more but I only counted those that I felt fairly confident were different individuals. This meant that during the day I had seen maybe 10 Swallowtails across both sides of Hickling Broad.
Tuesday was dull and cloudy and although we visited How Hill it was too cool and breezy for any Swallowtails to be flying, but there is still plenty to see here and we spent a couple of hours exploring the grounds and walking through the woods to the secret gardens.
On Wednesday we spent the morning at Horsey Gap and then stopped off for a cream tea (great for keeping the brownie points topped up). As it had turned out to be a nice day again with plenty of sunny spells and light fluffy clouds Jane said I could make the most of it and shoot off somewhere for the afternoon. I returned to How Hill to give it another go in better conditions and this time within minutes of walking along the path through the wet meadow there were two Swallowtails flitting from flower to flower on a patch of purple flowers, I couldn't decide if these flowers were some kind of thistle or knapweed perhaps, but they looked different to either of these that I see at home. Like I said earlier, I am not very good with wild flowers.
I then spotted another Swallowtail across the other side of the meadow which meant that for a while I had three in view at the same time. I spent the next hour or so in this spot just watching them and taking photos as the opportunity arose and at one point was joined by a couple of members of Norfolk BC and had a pleasant chat about various things butterflies and our thoughts on the current season.

Whilst watching the Swallowtails coming and going around this area, I saw a male chase a female and they spiralled high up into the air until the female just turned and dived headlong back down into the grass in an attempt to shake off her pursuer. He followed her down and flew along just above her and seemed to be trying to force her down until she managed to shake him off and made good her escape. I tried to follow them with my camera to catch the action but only just managed to get one shot that wasn't just a vague blur.

After leaving How Hill and with a bit of time to spare I decided to call in at Catfield Fen which is close by. I followed the narrow lanes and parked up in the small parking area and spotted a chap wearing a Butterfly Conservation top and stopped for a chat. It turned out he was doing a recce for a guided walk he was doing later in the afternoon and invited me to join them but unfortunately I needed to return to Jane before then (hmm!...didn't quite mean that how it sounds).
The interior of the fen here can be dangerous but there is a raised path around the outside from which it is possible to see Swallowtails and so I set off for a quick walk around to see if I could spot any. I only stayed here for about an hour but managed to spot two Swallowtails at different spots around the path, both flypasts, one of which came down the path towards me and flew past within a couple of feet.
So then, all in all I reckon I saw something like twenty two Swallowtails across all the sites visited between Sunday and Wednesday. There may have been one or two more but as mentioned above I have only counted those I was fairly certain were different individuals due to being seen a good distance apart.
My counts for the individual sites were;
Sunday 10th. Strumpshaw Fen - 6
Monday 11th Hickling Broad (inc. Weavers Way) - 10
Wednesday 13th How Hill - 4
Wednesday 13th Catfield Fen - 2
Out of those, I managed to photograph six different individuals, 2 at Stumpshaw, 1 at Hickling Broad by the Weavers Way, and 3 at How Hill.
Some that I saw were showing signs of wear and tear but others were in remarkably good condition still and although I suspect that numbers were just past their peak I think they should be flying for a little while yet.
The Swallowtails were the main target of course but there was plenty of other stuff to see as well...
Bye for now,
Neil
