Andrena humilis – Gog Mogogs

New species to me.

Description and notes
A distinctive, medium-sized Andrena, the female having a coat of golden hairs on the last two tergites. It shares this feature with the slightly smaller A. fulvago (Christ), but has dark hind tibiae, rather than pale ones. The male is one of the small group which have bright yellow markings on the clypeus. This species may be quite plentiful where it occurs, usually, but not exclusively, on sandy soils, but is decidedly local.

Andrena humilis

Status (in Britain only)
Listed as Notable B in Falk (1991) (now known as Near Threatened Nb).
Habitat
Most often associated with sandy soils, although also known from coastal head deposits where the soils are friable.
Flight period
Univoltine; May to July.
Nesting biology
May nest colonially or singly in areas of bare, firm, usually sandy, soil exposed to the sun.
Flowers visited
It seems to restrict all flower visits to yellow-flowered Asteraceae.

Parasites
The cleptoparasitic bee Nomada integra Brullé is specifically associated with this species. It has been found stylopised elsewhere in Europe.

Dusky Sallow moth – Eremobia ochroleuca- Gog Magog Meadows

A moderately sized moth with tawny or olive brown and straw coloured forewings, with a broad whitish central band, pinched in the middle and with a neat chequered fringe.Usually seen by day flying in sunshine during mid summer or nectaring on flowers and is particularly fond of Knapweed and Ragwort. Also flies at night.

Marbled White – Melanargia galathea- Gog Magog Meadows

Despite its name, the Marbled White is more closely related to the subfamily known as the “browns” that the “whites”. This butterfly is unmistakable, its black and white markings distinguishing it from all other species found in the British Isles. This butterfly is found in distinct and often large colonies, south of a line between Glamorganshire in the west and North-east Yorkshire in the east, although it is not found in much of eastern England. It is absent from Scotland, Ireland and the Isle of Man.
