A Rare Treat

Clifden Nonpareil, Catocala fraxini.  Crowborough, 4 September 2018.
Clifden Nonpareil, Catocala fraxini.  Crowborough, 4 September 2018.
This is a Clifden Nonpareil, sometimes called Blue Underwing. It was once resident in the UK, but died out, and was then seen only as an occasional immigrant.  It is re-establishing itself, but still is only seen a few times a year away from the coast.  So I was lucky that this specimen appeared on my garden fence above the light of my moth trap.

I saw it from my kitchen window before dawn and thought I might have a Red Underwing.

That would have been good because although these are not scarce, they rarely come to light, and I have only seen two, both at West Wickham Common.  But no!  It was bigger and better than that.

And it is big, one of our biggest moths.   The Old Lady is quite sizeable:

.. But it's not as big, and it lacks the flashy underwings.  For size, you might consider Hawk-moths; they are pretty big, like this Privet Hawk-moth that some trappers brought to Sevenoaks.

I saw one at Hayes the next year.  These were very impressive.  Incidentally, blue is a rare colour among moths.  I only know one other in Britain with some blue, and it's another Hawk-moth:

All of these were a real pleasure to see and handle.  But the Clifden nonpareil is the rarest.

Sevenoak Moths August 2018

There was a reasonable collection of late Summer moths in the trap at Sevenoaks Wildlife Reserve this month.  One moth was sitting on top of the trap - this one, Acleris emargana.

It's a species I have not seen before.  There is a confusion species, Acleris effractana, but as that lives in Scotland I think this identification is pretty safe.

Most of the others were quite common types.  This one:

Snout, Hypena proboscidalis.  Sevenoaks Wildlife Reserve, 29 August 2018
Snout, Hypena proboscidalis.  Sevenoaks Wildlife Reserve, 29 August 2018
Does not look the way we normally expect because it is a second generation specimen, darker than the first generation and lacking some of the normal markings.

The Square-spot Rustic is an autumnal species, basically brown but often with rich reddish undertones.  It's well named for its distinctive straight-edged spots.

This European Corn-borer is one I don't see very often so I was glad of the chance to get a good clear photo.  I took a mug-shot as well.  It was just an occasional migrant until the 1930s but is gradually getting established in the UK.  Over here, it actually lives on Mugwort rather than being a crop pest.

Ashdown Woods

Ashdown Forest looking south from below Church Hill car park, 19 August 2018
Hot and dry weather has been kind to this part of the Ashdown, which I think must never be entirely dry.  Water runs down this slope into a stream at the bottom.  Here, the heather is in full bloom (this is Ling, Calluna vulgaris) and there is plenty of bracken, broom and young silver birches.  The larger trees are Scots Pine.

This path runs parallel to the stream.  Here the uphill slope is to the left, and lush Pendulous Sedges line the path on the damper side, where water tends to collect.

Some old stonework, overgrown with trees and their roots, is part of the Old Mill.  I mentioned that in another post with photos from the same pathway, here: Ashdown Woodland Track.

There are several areas where one type of vegetation seems to run riot.  The Pendulous Sedges above are an example.

This is another.  I don't know what grass this is. The smaller clumps at the front are Wood Melick, but I'm not good at identifying grasses so the larger one has me stumped.  It is certainly doing well here, though.

Here's a photo from close by this spot, taken last year:

To show that it's not just grass that can take over a section of woodland.  These are Hard Fern, and I have not seen this many on one spot elsewhere.

Other inviting tracks lead off from this one.  Here's one - with a row of rushes in its centre, another sign of damp ground.

A few views of Wakehurst

A meadow at Wakehurst, West Sussex.  17 August 2018.

Wakehurst is a botanic garden in West Sussex, owned by the National Trust but run by the Royal Botanic Gardens, Kew.  It's half an hour's drive from my current house and I joined as a friend soon after moving here.

These are just a few shots from a recent visit. 

A path at Wakehurst, West Sussex.  17 August 2018.
It's styled as a "wild" botanic garden, but it only merits that name in comparison with Kew where almost everything is in glasshouses.  It's intensively tended and kept up.

On my way in I noticed some small Wollemi Pines for sale.  This is a rare tree.  (Wollemia nobilis, family Auracariaceae.) There are less than 100 specimens known in the wild.  As you might expect, these small potted plants were very expensive.  But later, on this path, I recognised the young conifers at either side - this is a Wollemi Pine pathway!  They are doing very well.  I don't think they would be selling them unless there were plenty of spares.

Sandstone at Wakehurst, West Sussex.  17 August 2018.
Sandstone at Wakehurst, West Sussex.  17 August 2018.
In common with many spots in Sussex, Wakehurst has several sandstone outcrops.  Picturesque tree growth like this is easy to find.  What's odd about this particular spot is that the path on this side of the wooden bridge does not seem to go anywhere.

Outside the Millennium Seed Bank are a set of plots with different soil types - gravel, hillside, chalk, hay meadow, wet meadow and others.  It is interesting to see examples of the different ecologies.

But one thing they don't seem to be able to do is produce clear and unambiguous signage.  The old version (on the left) just stopped my in my tracks.  What, it costs £25 to get in if you're a Friend?   And why is it free to enter the car park for a day, but also £10 to park for a day? 

The new version (probably produced because rates had increased) does away with the first oddity.  But it still says that an adult ticket is free.  If only the sign had read "Adult Ticket Holders" it would have been quite clear ...

Catkins

Hazel catkins on Hayes Common, 5 February 2017.
Hazel catkins on Hayes Common, 5 February 2017.
I was searching my photo folders with the key work "cat" and I came across a lot of interesting pictures, including cathedrals and catkins.  So here are some of the catkins.

This photo is what people probably think of first.  Hazel catkins in early spring.  This is the male reproductive organ, and you can tap off showers of pollen.  It is spread by the wind to the tiny red female flowers:

Hazel, female flower.  The Knoll, Hayes, 19 February 2017.

No petals, because they do not need to attract insects.  Just sticky stigmas, with some tiny yellow pollen grains already stuck on.

These catkins are one of the first signs of spring, showing new growth on the trees.  But quite a few different sorts of trees use catkins to reproduce.

Pussy Willow catkins in Jubilee Country Park, 15 March 2011.
Pussy Willow is what we called this where I grew up, because the catkins were soft and furry.  These ones have been rained on!  It seems to be more often called Goat Willow here in the south, which matches its scientific name, Salix caprea.  The female flowers are on separate trees and are also bunched up into a sort of catkin:

These are either Pussy Willow or a close relative.   Other catkin trees include:

Birches - this one is Silver Birch.

Oaks.  These rather straggly catkins can sometimes have their own parasitic galls, caused by the sexual generation of same gall wasp that produces leaf galls later in the year.

You can see the alder cones, but otherwise this looks a lot like a tall Hazel.  But these catkins can sometimes be quite showy.

On the Fence

Moths on the fence near my light trap.  Crowborough, 14 July 2018.
On any good mothing night there is a collection of moths near, but not inside, the light trap.  It's interesting that the moths that have chosen to rest on the grey wood are more or less neutral in colour, with some patterning that might help to disguise their outlines.

Though, disguised or not, some of them, like this Black Arches, are quite worth a closer look.

Nearby, on a patch with a little bit of alga and lichen growth, was a moth with a more colourful pattern.

And here are a couple of photos from that night just because I like them

 A mugshot of Udea olivalis, which usually rests with its antennae flat along its back - here, it's become alert.

And when I released the moths, this Canary-shouldered Thorn decided to park upside down ...

I'll do something non-mothy next time.

Country Park Butterflies

Gatekeeper, Pyronia tithonus.  Crowborough Country Park, 6 July 2018.
Crowborough Country Park is a small but scenic area managed by our local ranger.  It was a clay quarry as recently as 1980, and has since been improved as an amenity and nature reserve.  I walked round today and saw many butterflies.  We have had two weeks of hot dry weather, and yesterday a thunderstorm gave everything a thorough wetting.  The sun's back today and the butterflies love it.

The top photo is the first Gatekeeper I have seen this year.  It was in a pleasant glade.

On the way up to the glade I saw this Holly Blue on the path.  I had to follow it round to get this photo.  That is true of almost all my butterfly photos and all the day-flying moth shots, too.

Speckled Wood, Pararge aegeria. Crowborough Country Park, 6 July 2018.
Speckled Wood, Pararge aegeria. Crowborough Country Park, 6 July 2018.
The glade was being shared by Meadow Browns, Ringlets, Speckled Woods like this one, Gatekeepers like the one at the top, some white butterflies - some definitely Large Whites, some might have been Small Whites but they didn't stop near enough for me to tell.  And this big orange beauty feeding on a Marsh Thistle:

Silver-washed Fritillary, Argynnis paphia.  Crowborough Country Park, 6 July 2018.
A male Silver-washed Fritillary.  It was keeping high and I could not get really close, but this photo shows it nicely.  These Fritillaries are not really rare, their population is fairly stable, but they are still marked as of some concern, so it's good to see them. 

Also in the glade was a small moth, a Straw Grass-veneer:

Straw Grass-veneer, Agriphila straminella.  Crowborough Country Park, 6 July 2018.
Straw Grass-veneer, Agriphila straminella.  Crowborough Country Park, 6 July 2018.
Properly called Agriphila straminella.  This and other similar moths do not fly by day by choice, but they are very easily disturbed and they fly around to look for another resting-place.

On my way out I passed one of the park's ponds and photographed this Large Red Damselfly:

Large Red Damselfly, Pyrrhosoma nymphula.  Crowborough Country Park, 6 July 2018.

There were no dragonflies there at that time, but I had seen one earlier and I was told there were nymphs in the pond, so I'll probably see more later.
