About a dozen Rhingia campestris were noted on the lower slopes of Mill Hill, but there were probably many more than that. Hawkweeds were their flower of choice.

The photographic study shows the Rhingia hoverflies in the north Shoreham garden. The first one and three below show Rhingia  visiting the Spotted Deadnettle, Lamium maculatum, and its long tongue is visible.

Green Alkanet Rhingia hoverflies were frequent

 

Rhingia campestris hoverflies were frequent and preferred the Green Alkanet to the White Dead-nettle on the Waterworks Road and were also present in a Shoreham garden visiting Spotted Deadnettle, Lamium maculatum.

The two following species are thought most likely to be hoverflies.
 
This fly is on a Green Alkanet flower Rhingia campestris (not showing the snout)

The first one was discovered on Green Alkanet at the southern end of the Waterworks Road. The upturned snout indicates a species of Rhingia although this protuberance (elongated face) would seem more suitable for feeding on the prevalent White Dead-nettle rather than the plant it was on.

This suggestion was also made by Alan Hadley on the British Insects Yahoo Group
The Rhingia hoverflies have been identified as Rhingia campestris. This is the most frequently encountered of the two Rhingia. The larvae of this species breed in dung.

The lateral margins of the tergites (dorsal segments) are edged in black in R. campestris, this is clearly visible on the image posted. R. rostrata lacks this feature. Source.

The second smaller brown fly (above right photograph) was ubiquitous on wasteland like the Dovecote Bank.
