Hoverfly on Ragwort

This is a mimic of a bumblebee because of the short antennae and hoverfly face.
Merodon equestris var equestris
It was only the size of a Carder Bee.

Common Carder Bee Bombus pascuorum, favouring Restharrow on the Slonk Hill Cutting (south).

 
27 June 2005
A White-tailed Bumblebee, Bombus lucorum, entered a Shoreham kitchen and landed on a pink slipper.
 
16 May 2005
The black colour of some bumblebees makes them difficult to photograph.

The images on the right of the Red-tailed Bumblebee, Bombus lapidarius, was taken in the linear spinney of the south side of the Slonk Hill Cutting.

A small orange mite was seen on this bee. 

21 April 2005
The orange furry Carder Bumblebees favoured the white flowers of the White Dead NettleA handful of Red-tailed Bumblebees, Common Carder Bees Bombus pascuorum, favouring White Dead Nettle, and at least one Buff-tailed Bumblebee from the wooded path (linear spinney) by Slonk Hill South were observed in passing.

19 April 2005
A Red-tailed Bumblebee, Bombus lapidarius, nectared on Dog Violet on the lower slopes of Mill Hill.

17 April 2005
The Red-tailed Bumblebee,Bombus lapidarius, was definitely confirmed from the wooded path by Slonk Hill South and the Common Carder Bee, Bombus pascuorum, from Shoreham gardens and wasteland.

15 April 2005
There were scores of bumblebees in gardens and on wasteland on the edge of town. Buff-tailed Bumblebees were identified, but there were other species as well, almost certainly the White-tailed Bumblebee, Bombus lucorum; but I am not sure about the Red-tailed Bumblebee, Bombus lapidarius, as I was unable to confirm this one.
 
I have identified this as the White-tailed Bumblebee, Bombus lucorum.

It was one of several seen during the day, this one from the Dovecote Bank.

15 April 2005

This bee in the photograph on the left is very likely a queen Bombus pascuorum. Not the male of Anthophora plumipes which has the integument of the labrum, clypeus and lower paraocular areas (collectively the lower face) bright yellow; in addition the base of the mandible and the ventral surface of the antennal scape are all bright yellow. All these structures in your portrait are black.
 

3 April 2005
There were scores of Buff-tailed Bumblebees in gardens and the downs (Mill Hill) including, or perhaps mostly, queens. There was at least one Mining Bee as well in the back garden of 40 The Drive (near Buckingham Park), (TQ  219 063)
Adur Mining Bees

7 March 2005
At least two queen Buff-tailed Bumblebees flew around, crashing at least three times at full speed into the glass pane of the French windows at 40 The Drive (near Buckingham Park), (TQ  219 063).

2 February 2005
Just after midday, the first burst of sunshine of the year felt warm in a shade temperature of 9.7 ºC.
This attracted 25+ dark Honey Bees to a Hebe shrub in The Drive (near Buckingham Park), Shoreham, plus a queen Buff-tailed Bumblebee.

2 January 2005
A bumblebee flew rapidly over the back garden of 40 The Drive (near Buckingham Park), (TQ  219 063).
 

25 October 2004
Nothing of special note apart from the small bee (photographed below on the right) on the Devil's Bit Scabious. It was much slenderer and smaller than the Carder Bee. Its abdomen was also more distinctly "zebra" striped in black and white and not furry like the usual Carders. The legs are partly white in this specimen when bumblebee legs are usually black. The nearest match from the Collins Guide by Michael Chinery (p. 244) is Halictus scabiosa.
PS: The Old Collins Guide shows a better match for Lasioglossum malachurus, but this species has yellow legs. Neither of the illustrations are detailed enough to be sure as it could also be a species of Colletes. Colletes hedera is a feeder on Ivy late in the year. This last one seems most likely, but it is still not quite right.
The consensus on the British Insects (Yahoo Group) is that this small bee is a species of Lasioglossum, but the species is unlikely to be identified by a photograph (I did not think it was anything special when I photographed it).

The solitary bee is Lasioglossum xanthopum - the largest British species of the genus, with males that peak much later than any other species (typically late September/early October - we are still trying to work out how it mates as you rarely see females at this time of year). It is a rather calcicolous species and frequent on the Sussex downs, though I have never surveyed these late enough to see males. It is graded Nationally Scarce at the moment. It can be confused for the similiar Halictus rubicundus (slightly smaller with abdominal dust spots at the apices of the tergites as opposed to the bases like your photo).

Approaching dusk, it was nearly dark when I squelched the muddy trail of the lower slopes of Mill Hill.

The following photographs were taken in the Butterfly Copse (TQ 209 063) by the Waterworks Road.

Bombus pascuorum

This one is the Common Carder Bee, Bombus pascuorum. Its legs are all black.

This is my first bumblebee of July 2004, and there are plenty of bumblebees around. It was on the path outside my front garden in Shoreham town. The lemony colour rather indicates the White-tailed Bumblebee Queen, Bombus lucorum.

Jewel Bumble Bee (Photograph by Andy Horton)
A Red-tailed Bumblebee, Bombus lapidarius, crawled out of the long grass just south of the reservoir on Mill Hill. There was a small orange phoretic mite on its abdomen. (17 March 2003)
The bumblebee on the railway path near the Toll Bridge, Old Shoreham, was striped orange and black. This was the Buff-tailed Bumblebee, Bombus terrestris, which is the commonest species locally. The white tail is usually very clear with this species. (The White-tailed Bumblebee, Bombus locurum is similar but smaller.) 
(19 March 2003)
The hoverfly Volucella bombylans var. plumata was discovered near the copse on Mill Hill. This white-tailed hoverfly (pic) is a bumblebee mimic.

 Common Carder Bee in a Shoreham town garden on 17 August 2003
 This species is probably Bombus pascuorum, which does not look that same as the books because it loses its orange furry thorax as the summer wears on. It is a common species that is more likely to be overlooked because of its small size.

This hoverfly looks like the bumblebee mimic Volucella bombylans var. bombylans seen hovering around in the field next to the stream between the Steyning Road (A283) and the Waterworks (TQ 209 068).
17 March 2003

A Red-tailed Bumblebee, Bombus lapidarius, crawled out of the long grass just south of the reservoir on Mill Hill. There was a small orange phoretic mite on its abdomen.
I am tempted to say that the mite is a deutonymph of Parasitellus.

Vestal Cuckoo Bumblebee, Bombus (Psithyrus) vestalis, male worker. On Slonk Hill
Report of the Day

25 June 2004  at Lancing Clump meadows
 

Buff-tailed Bumblebees were frequently seen, taking the whole meadow they were common with numbers well over a hundred. A few seemed to be the larger Vestal Cuckoo Bumblebee, Bombus (Psithyrus) vestalis, Queen shown in the photograph above.

ID  by Matt Smith
Cuckoo bees lay their eggs in the nests of bumblebees and their larvae are fed and looked after by the bumblebee workers.
This is one of the most common cuckoo bees. It has a yellow collar band, and a white stripey tail, with small yellow side patches at the top of the white tail. Its wings are browner than the wings of bumble bees.
from Mrs Smith's Bumblebee page
Until recently, cuckoo bumblebees were once considered to belong to a separate genus (Psithyrus) in recognition of their distinctive appearance and their behaviour as parasites in the colonies of other bumblebees. Lately, experts have, by and large, agreed that all bumblebees belong to a single genus, Bombus, with Psithyrus as a subgenus. Cuckoo bees are similar in appearance to bumblebees, but they have a softer ‘buzz’, indeed Psithyrus means ‘murmuring’ as opposed to ‘Bombus’, which means ‘booming’. Other differences include the lack of pollen baskets on the legs and a sparser coat of hairs, through which the shiny black cuticle can easily be seen.

19 March 2003
A steady stream of orange-tailed bumblebees were observed flying eastwards over the shingle beach to the seaward edge of Widewater Lagoon. Over a period of two hours, a bee must have passed every 30 seconds and I estimated the total numbers passing at about 136. Later in the afternoon a smaller fly-pass occurred.

Report by Bob Kent (Lancing) via the Lancing Nature Smart Group
NB: The species was probably the Red-tailed (Jewel) Bumble Bee, Bombus lapidarius.
