Rewell Wood

 

I have written this same blog, around the end of April, for many years now and it has always been titled Pearl-bordered Fritillary. It marks the start of the butterfly season for me and usually consists of three parts, see and photograph the Pearl-bordered, see and usually fail to photograph the Speckled Yellow moth and then, in the afternoon, go looking for the Duke of Burgundy at one of its locations on the downs.

Today that all changed. The Duke of Burgundy had come to Rewell Wood.  How it got there is open to speculation but it was definitely flying there.

Pearl-bordered Fritillary

We found the first Pearl-bordered about a quarter past nine. The sun was starting to warm the ground but there was still a cool wind blowing. Ideal conditions, the butterflies were just starting to move but were still sluggish and thus giving good views as they basked in the sun.

They could also we found basking on the dirt paths which warm up faster than the surrounding vegetation.

All very much as expected until another butterfly came into view. At a distance, the right colour, but a bit on the small size and flying a bit closer to the ground, a Duke of Burgundy. A quick record shot and a phone call to Dave, who at this point was out of sight about a quarter of a mile away and then I had to make sure I kept sight of it until he managed to get back to see it.

He made record time. It is not an unusual butterfly for us to see but this was a first for us in Rewell Wood and he wanted to record it himself. He probably also wanted to check that I had the identification right. A Duke of Burgundy and it had only just turned nine thirty, something of a record as they don't usually put in an appearance until closer to eleven.

Although we are used to seeing the Duke of Burgundy on open chalk downlands it was, in the past, more a butterfly of coppiced woodland. So it is perhaps not unusual to find it somewhere like Rewell Wood. We did not see any of its favoured foodplant, the Cowslip, in the area but there were plenty of  Primroses growing which are from the same family Primulaceae. 

The mystery is how they got there. I am not aware of any colonies within a reasonable migration distance of the wood. An assisted migration or perhaps they have benefited from the " Fritillaries for the Future" program?

We saw probably half a dozen Dukes allowing for multiple sightings from some of them. This is a good number for a coppiced woodland so early in the season and suggests there may be a sustainable population there.

The other encouraging aspect is that in the past the Pearl-bordered had been holding on in just one or two areas of the wood. Today we found them along rides where we had not seen them before and in widely dispersed areas of the wood.

I have also seen a few Green Hairstreaks, one of my early season favourites, but as yet I have not been able to get a photograph of one.

Purple Thorn

 

Well the revamped kitchen is looking good but as well as being a bit lighter of pocket, I seem to have missed much of the Spring migration. Fortunately the moth season in the back garden has started and has kept me interested, although the catches so far have been poor.

As with last year I had nothing in the trap from the mid November to mid March except for one Light Brown Apple Moth and a Common Plume. My first real catch of the year was an Early Grey and a Double-stripped Pug on the 22nd March.

Early Grey - Xylocampa areola

April increased the catches a bit but I was still looking at five or six moths a night at best. Fortunately that included, new for the garden, Purple Thorn and a Dark-barred Twin-spot Carpet.

Purple Thorn - Selenia tetralunaria

Dark-barred Twin-spot Carpet - Xanthorhoe ferrugata

Other moths of interest were a couple of Brindled Beauty and a Powdered Quaker.......

Brindled Beauty - Lycia hirtaria

Powdered Quaker -  Orthosia gracilis

...... with the numbers made up with Common Quakers, Flame Shoulders, Hebrew Characters and a good number of Double-striped Pugs.

Common Quaker - Orthosia cerasi

Flame Shoulder - Ochropleura plecta

Hebrew Character - Orthosia gothica

A change away from the northerly winds and some more humid nights would be welcomed. I suppose the Spring moths are flying somewhere but I am not seeing many of them in the garden.

Emperor Moth

 

It being that time of the year again, the Emperor Moth lures were taken out of the freezers and Dave and I headed off to Iping Common to see if we could get any pictures.  At first it all seemed a bit disappointing, with no interest being shown in the pheromones, but after about half an hour the first moth appeared and proceeded to search in vain for the female it was expecting.

The moths soon learn that they have been duped and after fluttering around the lure for a couple of minutes and searching the adjacent grass tufts they loose interest and drift away.  Disappointing for the moth and disappointing for us as there is little chance of getting a decent picture when they don't settle.

What you are waiting for is the moth that is exhausted from the search and lands on an adjacent tree or bush for a refreshing nap. Give them a couple of minutes to settle and they are then very amenable to close approach and if you are gentle to moving them to a better perch.

It was also nice to get a view of the underside of the moth and to be able to record the eye spots on the underwing as well.

The Emperor Moth, Saturnia pavonia, is the only member of the Saturniidae family of moths found in the British Isles. The male flies during the day with the female flying at night. A strange strategy for the survival of the species but then the male is supposed to be able to detect the female at a range of a couple of kilometers so will probably find her whilst she is roosting.

We saw about a dozen Emperor moths on the day, with a maximum of three flying at any one time. They were in different parts of the common but it is possible that some followed us around or were attracted for a second time.

Talk to it nicely and the moth may even flash the orange underwing at you but you need to be quick with the camera as the opportunity will not be there for long.

All we have to do know is find a female to photograph. A slightly larger and to my mind more impressive moth. Also a much harder challenge.

And the lure goes back in the freezer for another year.
