About
eight Marbled White Butterflies
were spotted on the upper slopes with a further three on the lower slopes.
This was thought to be only a sample of a more numerous population of these
prominent butterflies that were mating in the area around of and just north
of the reservoir.
The brown
front edge of the wing shown in the photograph is not usually seen in this
species.

A
handful of the first Gatekeeper Butterflies
of 2004 were to be seen in the scrub.

The
Field
Scabious is the one in flower and I was
able to confirm the species from the leaves. But
the large yellow patches of Bird's Foot
Trefoil were no longer to be seen from
a distance.
At
least two Vestal Cuckoo Bumblebees,
Psithyrus
vestalis, were noted and identified from
the lower slopes of Mill Hill.

Amongst
the long grasses and flowers in the north-east corner of Mill
Hill, my first Large Skipper
of 2004 put in an appearance. I thought it was a Small
Skipper at first, until it opened up its wings.
An earlier probable Small Skipper
near an Elderberry Bush
south-east of the reservoir is not now a definite.

ID Page
On the
upper slopes of Mill Hill, there were a handful of Small
Tortoiseshell Butterflies, plus at least
five Meadow Browns,
half a dozen Common Blues,
and a dozen Small Heath Butterflies.
In the scrub there was a single Red Admiral,
in the woods to the north and north-west at least eight Speckled
Woods. On the lower
slopes the Small Heaths
were amorous and were estimated at 30+ with the occasional Meadow
Brown and at least two Common
Blues,
one female and one male. One Cinnabar Moth
flew in the weak sunshine.
Three
dried out fungi (toadstool-like) were discovered
on a dead tree within the scrub.
Other
plants noticed were a large clump of blue
Meadow
Cranesbill,
Geranium pratensis,
(could
be escaped Garden Cranesbills)
on the upper
slopes near the top car park; Perforate
St John's-wort,
Hypericum perforatum, in
glades within the cleared scrub; and Garlic
Mustard, Alliaria
petiolata, in a sheltered spot by the
steps in the north-west corner.

Much
to my astonishment, an early (one week early) Marbled
White Butterfly settled on a patch of
grass immediately in front of me on the lower
slopes of Mill Hill (at the northern end as the path leaves the open
into the Hawthorn scrub). A handful of battered Adonis
Blues were
mostly on the lower slopes, and 40+ Small
Heath Butterflies and a handful of Meadow
Browns were on the lower slopes and above
the ridge. A Small Skipper* fluttered
around an Elderberry bush
at the top of the path, where a spider
had caught a Cinnabar Moth and
two
Crane Flies in its web. One large butterfly
was disturbed and flew off with such rapidity that this was notable in
itself: it had a large hint of orange to it and the favourite must be a
Meadow
Brown.
Grasshoppers could be seen and
heard.
(*
Originally there was a possible doubt over the identity: it is now 90%
sure to be a Small Skipper with the profile of the Small Skipper, rather
than a Large Skipper, and a complete absence
of black markings on the underside of the wings. NB:
All the 2005 sightings really indicate that this could only have been a
Large
Skipper.)

On
a sticky humid day, I was not prepared for a butterfly
I did not recognise: when my eyes focused in and the features revealed
themselves and it looked more like a giant Dingy
Skipper
with clearer markings than any other
species. Alas, the butterfly was elusive just on the upper part of the
slope just down the path from the ridge when arriving from the south. This
area is scrub and long grass. At first I thought this could be a Dark
Green Fritillary, which would be an addition
to the Mill Hill list. The Dog
Violet food plant is within a few metres
of where it was seen. However, on reflection, I think this identification
is unlikely. On further reflection, the possibility is still there. I only
had a brief glance and the lower upper wing is not so brightly patterned
so it is conceivable that it is this species. There has been another possible
sighting of a Dark Green Fritillary and
photographs from Cissbury
Ring lay credence to this identification.
PS:
A subsequent observation has made this out to be a Painted
Lady Butterfly.

The
yellow patches on the ridge were expanses of Bird's
Foot Trefoil.
Just
north of the reservoir on the upper slopes, a worn (faded but not battered)
Painted
Lady Butterfly was seen as it fluttered
around and settled. On the way to Mill Hill
from the south-west, a Small Blue Butterfly
and a Meadow Brown
were seen on the footpath at the top of the road embankment. Adonis
Blues
were mating down on the lower slopes.

A
small clump of Spotted Orchids, Dactylorhiza
fuchsii, are recorded on the road
embankment (north-west) side to the south of Mill Hill, where the yellow
patches are Bird's Foot Trefoil
in flower. Eyebright
was in flower on this bank. The lower slopes
recorded mostly
Common Blue
and Small Heath Butterflies.

On
the road embankment by Chanctonbury Drive (SE of the bridge) the dozen
or so Small Blues were
seen immediately with a Painted Lady Butterfly,
which was past pristine condition without being faded or battered. In Chanctonbury
Drive over the grass a Red Admiral Butterfly
fluttered by.

On
the town side of the bridge leading to Mill
Hill that transverses the main A27
road, on the east there is a small Hawthorn copse (at the top of
Chanctonbury drive, north side) leading to the grasses of the trunk road
steep bank. In this small garden sized plot of long grasses and scrub,
between 30 and 50 was my estimate of the number of Small
Blue Butterflies. At least a dozen of
these were seen all at one time, including at least two pairs mating, but
its was difficult to work out their numbers because it was in the afternoon
and they hid down in the long grasses most of the time.
|
|
This
constitutes the first positive record of this butterfly for Mill Hill,
which makes the number of butterflies as
26 definites. If these numbers are repeated all along the road embankment,
the colony must number several hundred. A female Common
Blue Butterfly looked much larger in comparison
to the smallest of the British blues and the Speckled
Wood Butterfly that arrived was larger
still.

The
first positive Wall Brown Butterfly
of the year in the lower Adur valley was seen on the path between the Waterworks
Road (Old Shoreham) and Mill Hill (south of the A27
Shoreham by-pass). It flew strongly and it
was tricky to confirm the identification (this butterfly may be under recorded)
and even more tricky to photograph. The Wall
Brown Butterfly was seen on and over the bridleway
path running west to east and next to the road embankment.
A
small white butterfly was flying strongly over the southern part of the
upper slopes of Mill Hill. This was definitely
identified as a Green-veined White Butterfly
which increases the confirmed New Millennium Mill
Hill butterfly list at 25 plus two probables.

Down
on the lower slopes of Mill Hill, the Horseshoe
Vetch had ceased its main flowering and could
be seen on the ground, but the spectacular bloom of a fortnight before
that could be seen from half a mile away had now receded to a green expanse.
Blue butterflies were immediately noticeable. On the normal transect travelling
the distance of the path to the copse and back, 28
Adonis
Blue Butterflies were counted as positive
single butterfly sightings (24 males,
3
females and
one
indeterminate) with only one Dingy
Skipper settling although there could
have been more. All three definite Adonis
females were the conventional chocolate brown
colour. The midday visit also yielded an estimated 50
Small
Heath Butterflies.

On
the top ridge of Mill Hill the turf is full of Creeping
Cinquefoil* and buttercups
and this may have led me to miss the patches of Horseshoe
Vetch above the ridge on the steeper bits
because the yellow plants merge into one another and it was only by walking
over the incline that can I see the ground flora of the salt-blasted grass
turf exposed to the south- westerlies. This is the area where model aircraft
are launched into the wind. There was one male
Adonis
Blue Butterfly that caught my eye. There
were just another seven of these bright blue butterflies to be seen on
the lower slopes. (*
The precise species is under enquiry.)
23
May 2004
The
blooming of the Horseshoe Vetch
was even more impressive on the lower slopes
than last year after the recent rain, but there were the first signs that
the flowers are beginning to diminish. Of the 19
Adonis
Blue Butterflies, just one was a brown
female with a lot of blue on its upper wings
and body. Small Heath Butterflies,
Dingy
and Grizzled Skippers
were there as well as would be expected at this time of the year.

The
first Adonis Blue Butterfly
for Mill Hill was seen on the upper slopes with a Small
Tortoiseshell Butterfly south of the reservoir
near where the old stile was and by the Elderberry
bush and the red dog bin.
The
lower
slopes were spectacularly blooming with
Horseshoe
Vetch in their annual May display where
a further Adonis Blue Butterfly
was seen at the northern end. (The yellow in the northern lower agricultural
field are buttercups and related plants.)

Hill, including the southern end of the steeper slopes that was not showing
at all a week ago and could not be seen from a distance three days ago.
Almost all the Dog Violets
on the open chalk face had diminished and the blue and pink was that of
the Common Milkwort, Polygala

The
only butterflies on the lower
slopes of Mill Hill were Dingy Skippers
(12),
Small

My
first Small Heath Butterfly,
the first of just three, were amongst a handful of Dingy
Skippers and a Brimstone
Butterfly on the lower
slopes of Mill Hill.
26
April 2004
As
the first Horseshoe Vetch
and Milkwort
were beginning to flower on the lower slopes
of Mill Hill, I observed the first skipper butterflies of the year. An
amorous pair of Grizzled Skippers
danced around the bramble borders, with at least one Dingy
Skipper and two or more Brimstone
Butterflies. The day flying micromoth
Pyrausta
nigrata could conceivably be mistaken
for the Grizzled Skipper.
This moth is slightly more prevalent of the two. In the scrub in the north-west
of Mill Hill there were two Speckled
Wood Butterflies and a single Peacock
Butterfly. On the open upper
slopes there was another Brimstone
and a handful of Small Tortoiseshells,
orange in colour but not fresh, the orange dulled by age.

It
was the long probing beak on the short turf of a Rook
on the top of Mill Hill that gave it away. Its grey face was apparent
even before I fastened my binoculars on this solitary corvid. Only about
one in a thousand large black corvids locally are Rooks,
the rest are Crows
with Jackdaws
classed as small.
A
solitary toadstool was amongst the still short grass near a Hawthorn bush.
I recognised it immediately as a Morel,
Morchella
esculenta, because of its unusual distinctive
appearance. I had not seen one before and although an edible species, I
left it in its place just south of the car park.
The
male
Kestrel
hovered
over the lower slopes, whereas the female
was seen at a much lower trajectory flying over the outskirts of the copse.

Red Campion, Daffodils
and
Bluebells
in flower above the ridge on the upper
slopes. A Kestrel
hovered over the ridge and it dived, wings pinned close to its body for
an impressive display. Lackey Moth caterpillars
clambered over a Hawthorn, and it is these caterpillars that weave the
white tent or cocoon (pic).

Sweet
Violets in purple are scattered with hundreds
of plants over the sheltered bits of Mill Hill, most of them violet
in colour but in the Triangle area of the middle
slopes all white flowered plants were present. This is a very common
wild flower. On the lower slopes the hundreds
of plants have little or rudimentary leaves and I am not sure if these
were the same species.

After
reports of Buzzards over

I thought a quick visit to Mill Hill could prove interesting. A couple
of Kestrels
were performing acrobatics on the thermals and they both looked like the
more colourful male of this raptor species. A few Lapwings
wheeled overhead but the large flocks were over the grazing fields to the
east.

It
would have come as a bit of a shock to me if I had not already received
a handful of local reports of Painted Lady
Butterflies. A flutter of orange and the
unmistakable patterns (now that I can recognise them instantly: to novices
they could resemble a Small Tortoiseshell
Butterfly) of a Painted
Lady Butterfly that flew steadily over the
southern section of Mill Hill. Later, a second Painted
Lady flew around the copse
and settled on the Beech
leaves still on the tree and several times on the grass. I now think these
are possibly immigrant butterflies
rather than hibernating adults that have awoken. I am still undecided though.

Incongruously
on a loose twig, a few bodies of the Jew's
Ear Fungus, Hirneola
auricola-judae, were discovered amongst
the mosses underneath the Hawthorn scrub. Incongruous, because none
of the living trees nearby were hosts to this fungus. An old bird's nest
with a moss base was visible high up in the Hawthorn.
In
the copse at the top of Mill Hill, the
workmen had sawn down some of the pine trees and made a small fire. I think
these were the Corsican Pines,
Pinus
