Sphecodes sp- Lode

Specodes sp

Four new species of Sphecodes bees to add to the record on the lode-hornigsea field system.

  • Sphecodes rubicundus
  • Sphecodes  ephippius
  • Sphecodes geoffrellus
  • Sphecodes longulus (which is tiny only a few mm long)
  • Already recorded is Sphecodes monilicornis

Lasioglossum laevigatum – Lode

New species for me

Distribution
Mainly confined to southern England, with a few records from further north. Not known from Scotland, Ireland or the Channel Islands. A local mining bee but sometimes abundant where found. A western Palaearctic species, the range extending from Britain to the Urals, and central Iberia to Iran.
Status (in Britain only)
This species is not regarded as being scarce or threatened.
Habitat
Particularly associated with calcareous grassland; occasionally open woodland on chalk, wooded heathland and fenland.
Flight period
Females from mid April to late September; males early July to September.
Nesting biology
Nesting habits are apparently largely unknown. In Germany, the species is stated to be “solitary” (i.e. non-social) (Westrich 1989).
Flowers visited
Lesser celandine (Ranunculus ficaria), broom (Cytisus scoparius), plum (Prunus domestica), wild parsnip (Pastinaca sativa), wild carrot (Daucus carota), willow (Salix species), speedwell (Veronica species), guelder-rose (Viburnum opulus), tormentil (Potentilla erecta) and ragwort (Senecio species).

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.
