24 June 2016
The smaller Robber Fly, Machimus atricapillus, were occasionally seen (10+) and were seen mating on the lower slopes of Mill Hill. There were more of this predator than seen before.

Cattle were grazing in the pasture to the east of Mill Hill and sheep in the nearer meadow below (to the west). 

18 May 2016
 

Crane-flies were seen in a field next to Ladywells.


12 April 2016
A Buzzard soared over the lower slopes of Mill Hill in the bright blue sky. Common Bee-Flies, Bombylius major, were frequently seen.
Subsequent perusal of the blurry photographs showed one of the Bee-flies had dotted wings indicating the scarce Dotted Bee-fly, Bombylius discolor.

10 August 2015
Two robber flies were noted: the smaller Robber Fly, Machimus atricapillus, on the southern steps of Mill Hill and the much larger Hornet Robber Fly, Asilus crabroniformis, on the top meadow. Both of these flies will prey on butterflies

19 July 2015
The predatory Robber Fly, Machimus atricapillus, was seen at least twice on the lower slopes of Mill Hill.

My first Common Bee-Fly, Bombylius major, of the year was spotted visiting Ground Ivy on the cyclepath verges, north of Old Shoreham.

Robber Fly on the lower slopes of Mill Hill 
It looks like Machimus atricapillus ... the antennae look good for it (the very similar M. cingulatus has a slightly shorter arista) and is associated with chalk and limestone grassland. Under Enquiry (link)

Robber Fly (unidentified) 
It is possible that it was a species of  the Machimus-group of Robber-flies

7 August 2013
 A Hornet Robber Fly, Asilus crabroniformis, landed on the Pixie Path in front of me.  (ID not certain. It might have been the fly above.)
 
21 May 2013
Biblio species, St. Mark's Fly were common over the Pixie Path to Mill Hill. This fly comes out in large batches on the downs and their abundance can be a by nuisance. 

 
4 October 2012
Crane-flies were seen on the lower slopes of Mill Hill
11 September 2012
I spotted my first Hornet Robber Fly, Asilus crabroniformis, of the year on the middle slopes of Mill Hill (Triangle area). 
25 July 2012
Dichetophora (Sciomyzidae) fly on the upper part of Mill Hill
It is most likely to be Dichetophora obliterata (female).

ID on Diptera.info by Mucha Fero and Jonas Mortelmans

Dichetophora obliterata: an attractive fly with a rust coloured abdomen and grey thorax. The thighs are quite distinctive, being orangey-red just above the knee joint but pale in the upper parts nearer to the body. This widespread species is known as a snail-killing fly. The larvae are predatory on snails.

2 April 2012
There was a chill breeze and no butterflies were seen in the afternoon, not on the Waterworks Road where the two Bee-flies visiting the patch of Ground Ivy were too energetic to photograph or even to identify to species species they would not settle. They were paler than normal, one was a pale orange when viewed from the side.

26 March 2012
A Common Bee-Fly, Bombylius major, (first of the year) was spotted over the path amongst the Hawthorn scrub on Mill Hill.

The predatory small Dance Fly, Empis tessellata was seen with its prey of a smaller fly.

Crane Flies on Mill Hill26 April 2011
Crane-flies, Tipula,were mating on the lower slopes of Mill Hill. A handful were noted, but I expect there were many more.

8 April 2011
Common Bee-Flies, Bombylius major, flitted around the Butterfly Copse near the Waterworks Road, Old Shoreham.

3 April 2011
A Common Bee-Fly, Bombylius major, was also spotted amongst the Dog Violets on the lower slopes of Mill Hill.There was another one amongst the Alexanders at the top of Buckingham Park, north Shoreham.

22 March 2011
The first Bee-fly of the year was seen on the southern steps to the lower slopes of Mill Hill. It was not identified to species.
 


 

1 August 2010
Two large Hornet Robber Flies, Asilus crabroniformis, my first of the year settled on the Pixie Path (next to Frampton's Field, Old Shoreham).

18 April 2010
A Dotted Bee-fly, Bombylius discolor, was spotted hovering about and visiting Dog Violets on the lower slopes of Mill Hill. Its identity was confirmed by a  poor photograph.

The first Bee-flies of the year were seen near where Cowslips were in flower on the Downs-Coastal Link Cyclepath.
 

23 July 2009
Under a cloudy sky at the top of the Pixie Path the first Hornet Robber Fly of 2009 settled briefly.

6 April 2009
Three Bee-flies in the north-west scrub on Mill Hill did not settle. They were most likely to be the rarer Dotted Bee-fly seen in this location before. However, it was a Common Bee-Fly, Bombylius major, that landed on the steps of the Butterfly Copse next to the Waterworks Road.

5 April 2009
There were frequent Dotted Bee-flieshovering in mid-air and visiting Ground Ivy on the Coastal Link Cyclepath near the Cement Works.

29 March 2009
An unexpected treat was three or four individual Dotted Bee-flies, Bombylius discolor, using their long feeding tubes to take nectar on a large patch of Ground Ivy, Glechoma hederacea.

This is a notable record of a rarely recorded fly and is probably the first for Lancing. Bombylius discolor is a declining BAP (Biodiversity Action Plan) species. In Great Britain this species is classified as Nationally Scarce.

Previous Record on Mill Hill

23 March 2009
At least two Common Bee-Flies, Bombylius major, were also spotted hovering over the vegetation bordering the grassy area at the top of Chanctonbury Drive, Shoreham, south-east of the bridge over the A27 to Mill Hill.
 


 
22 June 2008
The small  Soldier Fly, Chloromyia formosa, illustrated on the left was seen occasionally and was probably frequent at the top of Buckingham Park, Shoreham, amongst the vegetation under the canopy of trees. This is not a hoverfly

Marmalade Flies, Episyrphus balteatus, were seen on Mill Hill

6 June 2008
A few of the distinctive Panorpa flies were seen amongst the Privet and Brambles on the lower slopes of Mill Hill

11 April 2008
On a breezy afternoon, the first two Common Bee-flies, Bombylius major, of 2008, buzzed over footpath that runs along the south of Frampton's Field, and another one was seen at the top (north) of The Street, Old Shoreham.

29 March 2008
 

One of Britain's favourite butterflies may be being killed by a parasite. The Small Tortoiseshell Butterfly has suffered a dramatic decline in recent years and it is thought that a tiny parasitic fly, Sturmia bella, is the cause. The butterfly caterpillars eat the fly's eggs, found on nettles, which then hatch, killing the host. The charity Butterfly Conservation Society and the Dept. of Zoology at Oxford University's are conducting research to find out if the fly is to blame. It is a common parasitoid of Nymphalidae in Europe but nothing can be said as yet of the British status.

1 February 2008
A fly on a Dandelion at the top of  McIntyres Field, north Lancing, was my first fly noted this year. 

25 September 2007
A Hornet Robber Fly was seen on the Slonk Hill Cutting south in the open overgrown bit east of the hedgerows that close in on the path. 
12 September 2007
A Hornet Robber Fly was seen on Mill Hill south of the Reservoir. These flies are very wary and I find it nigh impossible to get near enough for a decent photograph.
12 August 2007
Hornet Robber Flies were seen on the Pixie Path and on Mill Hill at the top of the steps leading down to the lower slopes
 
3 August 2007

The first Hornet Robber Fly seen this year was seen on the Buckingham Cutting south.

2 July 2007
 

 
There were a handful of the above flies on Stinging Nettles and other vegetation at the top of Buckingham Park, Shoreham. I thought the fly above was a hoverfly at first, but I now think it is probably not one.
 
24 April 2007
My first Common Bee-fly, Bombylius major, of the year was seen at Cuckoo's Corner.
 
 
The Crane-fly, Tipula species were mating in the same area of Garlic Mustard and Wild Carrot north of the car park and the gate at Cuckoo's Corner.
 
13 April 2007
The Crane-fly, Tipula species, was seen on the lower slopes of Mill Hill with a handful noted.
 
9 March 2007
Yellow Dung-flies, Scathophaga stercoraria, were already common (over a hundred seen) on the Alexanders on the edge of paths everywhere.
 
2 March 2007
In a brief burst of early afternoon sunshine, I spotted my first Dung Fly at the top of Chanctonbury Drive (SE of the bridge to Mill Hill).
