On
Slonk Hill, there were so many orb webs of the Garden
Spider, Araneus
diadematus, it would seem that any butterflies
would have had a difficult job avoiding them. No butterflies were seen
on a passing visit along the overgrown path on the southern side. At least
one isolated Kidney Vetch
was still in flower.

A
pair of Common Lizards
were surprised resting on an ant's nest on the south side A27
road embankment immediately north of Buckingham Park, under an overcast
sky. At first I thought there were no butterflies
around except for the omnipresent Small
Whites which seemed to be everywhere in
gardens and wasteland and footpaths, but then in the area of the Brambles,
three Comma
Butterflies, one Red
Admiral and a Speckled
Wood Butterfly appeared in quick succession.
The Garden Orb Spiders were spinning their webs. Two Squashbugs, Coreus marginatus, were on the Blackberry fruits. The small hoverfly, Sphaerophoria scripta was noted and then another larger one landed on a leaf very quickly and then flew off. The hoverfly in the photograph above landed on a leaf very quickly and then flew off. It is Erastalis tenax (the Drone Fly) remarkably mimicking a Honey Bee. (I cannot see any value in mimicking a Honey Bee though?).

I
checked out the crumbly north bank of Slonk Hill, not expecting anything
of note. Snails (pulmonates) of two species in the photograph below were
both common. (These are not common on Mill
Hill and snails were a target of biological collecting on Mill
Hill [? exact location] in the recent past.) The
tower-like snail is probably Cochlicella
acuta.
The Eyebrights were taller than on Mill Hill and the only butterflies present were a handful of Small Whites. The grasshoppers were very lively. Devil's Bit Scabious was in flower. Dense youngish growths of Horseshoe Vetch were noted, not the very small seedlings, but the pinnate leaves lying prostrate with the ground. Bird's Foot Trefoil was in flower in small amounts.

At
first I thought it was the Small Blue
again at the top of The Drive (opposite Buckingham Barn on the south bank)
and then the possibility of a Brown Argus
was foremost, but it turned out to be a female
Common
Blue. This is confirmed by the spots on
the underside.
I think
the idea is to get a good look at the underside, or a photograph and match
up the spots to identify a Brown Argus.

I
made a slight detour along the Slonk Hill (South Bank) trail and I noted
the fall in the numbers of Gatekeeper Butterflies
with only one positively recorded, but in the woodland Speckled
Woods were frequently seen with at least
twenty crossing my path. At the top of The Drive (opposite Buckingham Barn
on the south bank), a grey Small Blue Butterfly
was seen, possibly the same one seen on 25
July 2004. This second brood Small
Blue is a notable record. (At this time
of the year, small Common Blues
are around, but this identification was confirmed with a clear photograph.)

Temperatures
reached 28.8 ºC with a steady breeze and high humidity (54% to 82%)
(the lower humidity coincided with the higher temperatures) so it was not
an optimum day for butterfly watching.

No
butterflies
were recorded on the north bank of Slonk Hill in the area of Horseshoe
Vetch and certainly no Chalkhill
Blues on either side. In contrast over 200
Chalkhill
Blues were seen on the lower
slopes of Mill Hill yesterday.
1 August
2004
Despite
the emergence of hundreds of Chalkhill Blue
Butterflies on Mill
Hill, there were none to be seen on the south embankment of Slonk Hill
opposite the extensive Horseshoe Vetch
on the northern side. The
probablility is that this patch of the more upright Horseshoe
Vetch does not support a Chalkhill
Blue population, but this will have to be
investigated to confirm or otherwise.
There
was, however, at least 15 and probably 20 Chalkhill
Blue Butterflies on the road embankment
at the top of The Drive, Shoreham, opposite Buckingham Barn. This could
be because of the small patches of Horseshoe
Vetch on the southern side or because of dispersal
on the Mill Hill butterfly population.
25
July 2004
The
noteworthy butterflies were the two Small
Blues definitely confirmed at the road
embankment at the top of The Drive, Shoreham-by-Sea, of which one was in
a clean newish condition and the second one in the photograph was worn.
My suspicion is that these butterflies were overlooked by me in previous
years (possibly identified as Common Blues
or Holly Blues).
The banks was covered in spider's webs and there were also at least two
Common
Darter Dragonflies.

Despite
being the most prevalent of the butterflies in late July, it is not so
often that Gatekeepers
are observed actually mating, compared to many other butterflies. One 6-Spot
Burnet Moth was confirmed in what did
not amount to a visit, but more passing by on the path which was nearly
so overgrown to be impassable. The apples were nearly edible and the blackberries
were almost ready for picking.

July 2004
As
the sun struggled to come out, so did the flying insects: hoverflies
(at least five species) and butterflies (eight
species in Shoreham town) in their dozens and
scores, with bumblebees. This was just in a twenty
minute detour along the road embankment of Slonk Hill South which showed
all the eight species, and probably more if I had time to search. The highlights
were a completely unexpected Small Blue
(the first recorded in July) and a pale coloured Gatekeeper.
The most numerous butterflies were the Gatekeepers
and Small/Essex
Skippers with numbers seen around midday
over 40 each and many more hiding in the longer grasses. The other species
in order of prevalence were Meadow Browns
(20+),
Large
Whites, Small Whites, Holly Blues
(4+) and at least two Red
Admirals.
At
the time of writing all the hoverflies have not been positively identified,
but the following four were definites: the Marmalade
Fly, Episyrphus
balteatus, Syrphus possibly
vitripennis ?, Eupeodes corollae,
Volucella
bombylans and at least one much
smaller species.

It
is really a pity that the noise of the traffic makes the area of the embankment

noisy to be pleasant.

Buffetted
by a Strong Breeze (Force
6) from the south-east, there were just
nine butterflies of five species to be seen
in an hour in the late afternoon. All were recorded on the Slonk Hill South
Trail, mostly at the Buckingham Road end, where there was a profusion of
Pyramidal
Orchids in flower.
The
list did include my first Comma Butterfly
of the year and the first in the Adur district (but an earlier April record
of one was seen in Tottington
Wood near Small Dole). This butterfly
appeared more more orangey than usual. I think this is a characteristic
of the first brood of the Comma
and this butterfly did appear slightly battered and was not pristine. The
other butterflies of one each at the western end were a Small
Blue, a Meadow
Brown, a Red
Admiral and a Speckled
Wood in order in which they were seen.
On the road embankment to the east where the Spotted
Orchids were losing their petals, there were
just four more Meadow Browns.

A
Common
Darter joined a Common
Blue Damselfly with two Meadow
Brown Butterflies, and then a shower soaked
me. on the path parallel with the A27 Shoreham
By-pass, on the southern side near the Buckingham
Park end. The cocoons
of the Burnet Moths were noticed on the grasses
and tall plants.

On
the southern embankment of the A27 Shoreham
By-pass, near the Buckingham Park end, there
were a pair of amorous skippers, but I was unable to confirm that they
were
Small Skippers*
which they appeared like, or the very similar Large
Skippers.
The
red flying insect was a Cinnabar Moth.
(*
The earliest date that I have photographed Small Skippers is 26
June, but they have been identified positively earlier than that. Large
Skippers have been photographed from 21
June.)
There
were two Common Blue Damselflies, Enallagma
cyathigerum, in the long grasses. This
was the first positive record of these damselflies on these Nature
Notes pages.
Adur
Damselflies and Dragonflies
Plants observed (not mentioned before) included Trailing Bellflower, Campanula porscharskayana, an alien garden escape in the linear wood between the gardens and the road embankment; Wild Carrot, Daucus carota, and Selfheal, Prunella vulgaris, on the bank; Garlic Mustard Alliaria petiolata, Yellow Rattle, Teasel, Weld, Kidney Vetch (with the small green beetle*) and numerous other herbs and grasses. (*The most likely species for the green beetle seems to be Cryptocephalus aureolus.)

On
an overcast breezy day with showers and rumblings of thunder, it was the
Pyramidal
Orchids that had taken over from Spotted
Orchids on the southern bank of the A27
Shoreham By-pass (Buckingham
Cutting to Slonk Hill
South).
The
only
butterflies in flight were a couple
of Meadow Browns.
There was one Burnet Moth (or possibly
a Cinnabar Moth?) in flight and one Burnet
Moth caterpillar seen crawling up the stalk of a tall (24+ cm) Greater
Bird's Foot Trefoil
plant. The White-tailed
Bumblebee, Bombus lucorum,
was identified later, the first record on the Nature
Notes pages.
The
Small Blue Butterflies were no longer to be seen.

I
have underestimated the number of Small
Blue Butterflies on the road embankment
on Slonk Hill South as I was not looking in the prime spot where the Kidney
Vetch grows mostly on the A27
By-pass roadside at the bottom of the steep crumbly slope, whereas I usually
approach from the boundary copse on the south side. A further twenty of
these butterflies were seen in different areas from where they were previously
recorded. This brings the cumulative total actually seen in different areas
to well over a hundred and with this tiny butterfly, most of them remain
unseen, so the actual numbers must be much higher.
The
first Small Skipper*
of the year nectared on Kidney Vetch.
(* Only the unmarked
orange side view was observed: I was sure of my identification until I
mistook a Large Skipper
for a Small Skipper
on 21
June 2004.) At least one male
Meadow
Brown Butterfly was restless in the breeze.
There were numerous clumps of Bird's Foot
Trefoil in flower and Ox-eye
Daisies. Yellow
Wort was flowering in the late morning.
It is also looked as though the Chinese
Bellflower, Platycodon grandifloris,
was naturalised on the bank.

A
dark
brown weak flying moth (image)
was also disturbed as it tried to hide rather than fly away. This moth
was identified by Ian
Rippey (Ireland) on UK
Leps (Yahoo Group) as the Burnet Companion
Moth, Euclidea
glyphica, a common day flying moth
(May-June) mainly of chalk and limestone areas, whose larvae feed on Bird's
Foot Trefoil, Lotus corniculatus.

There was a rather dramatic large violet coloured plant near the roadside and sheltered by a signpost. This is the alien Salsify, Tragopogon porrifolius, a native of the Mediterranean which is edible but with a taste that is not popular in England. It is grown in gardens and has naturalised in several places in Britain.

Close
examination of the Horseshoe Vetch on
Slonk
Hill (A27,
north road embankment) revealed this plant to be growing upright in clumps,
In this respect they differ from the prostrate form on the lower
slopes of Mill Hill on two main counts:
1)
the lack of long green stems and leaves running prostrate over the ground
means that although the flowers may be impressive it does not dominate
the flora in quite the same way as the prostrate forms and there are not
nearly as many leaves and consequently this form does not support as many
Chalkhill
Blue Butterflies, if any at all.
2)
although environmental differences seem most likely, there may a chromonsonal/genetic
difference; it could be diploid instead of tetrapoid but needs an expert
to distinguish the two.

There
were a handful of small dark blue butterflies fluttering over the Horseshoe
Vetch and Common
Vetch on the steep chalk south-facing bank
in the humid sunshine as the traffic roared past. These butterflies were
Small
Blue Butterflies, which is the first record
on these Nature Notes pages. I counted half a dozen, but I would estimate
that there were at least a dozen in flight in the hot sunshine around midday,
but they were not be be seen when I returned in the evening. These
butterflies were smaller than a Grizzled Skipper.
Some
of the yellow flowering was because of
Sow
Thistle and there was an Ivy covering
on the top of the cliff. The Slonk Hill banks on both side of road are
rich in wild flowers and although not abundant in butterflies,
can show a variety.

Notes:
On
the Shoreham bypass, I heard that the Vetch
used to seed the cutting faces when that road was constructed was a continental
variety, and not the genuine wild UK product. That's why it looks so odd!
