Nomada ochrostoma_homonym Zetterstedt, 1838, Nomada quinquespinosa Thomson, 1870, Nomada alboguttata var. liburnica Friese, 1921, Nomada alboguttata var. suerinensis Friese, 1921, Nomada alboguttata etizenensis Tsuneki, 1975

Description and notes

Discovered in Britain from east Kent in June 2016.

Distribution

Widespread across much of central and northern Europe, from France eastwards to Slovenia, and northwards to Fenno-Scandia and Russia

Identification

To separate this species from its congener N. baccata:

Nomada alboguttata: Large, forewing length 7-10mm, scutellum distinctly raised above the level of of the plane of the scutum (see image below).
Nomada baccata: Small, forewing length circa 5mm (given as up to 6mm in European literature), scutellum on the same level as the plane of the scutum.

Habitat

Sandy places on heathlands and open woodland

Flight period

A partly bivoltine species; from the beginning of  April to the middle of June, and again from the end of July to the end of September

Nesting biology

Probably a cleptoparasite of Andrena barbilabris in Britain. Elsewhere in Europe it is known that Andrena barbilabris is the major host, but it is probably also cleptoparasitic on A. ventralis (Westrich, 1989) and possibly A. argentata.

Flowers visited

As this is a cleptoparasitic species, all flower visits will be for nectar only. Westrich (1989) lists the following plant species as nectar sources: Salix (Salicaceae); Taraxacum officinale (Asteraceae); Frangula alnus (Rhamnaceae); Jasione montana (Campanulaceae); Succisa pratensis (Dipsacaceae).

Smit et al. (2004) citing others lists Hieracium sp., Taraxacum officinale (Asteraceae) and Salix repens (Salicaceae) as nectar sources in the Netherlands
