Apart from two people the vast beach was almost empty other than dozens of birds searching the shoreline at low tide.  On the way there we had seen a few moths and butterflies, a tiny 2cm froglet, disturbed two roe deer and watched swallows swooping and terns diving into the sea.   I was excited to see a black and white Pied Hoverfly (Scaeva pyrastri) which as a migrant species  is not common in Scotland.

This is a migrant which reaches Britain around June from southern and central Europe, breeding here to give a generation in late summer. Although it is known to overwinter in central Europe, there is little evidence of this from western Europe suggesting that it annual occurrence is totally dependent on immigration (Speight, 1998). In Ireland and western Scotland, the earliest records are in July, suggesting that it is does not usually manage to breed in these areas
Widespread in the lowlands of the southern half of Britain. In northern England and southern Scotland records are noticeably clustered along the east coast, as one might expect for a migrant species. It seems to be scarce further north in Scotland, although it is recorded north to Shetland. The numbers of records received vary greatly between years
