(2012) the species is also found within Bulgaria, Macedonia and Ukraine. The northern limit for this species may be northern Germany (Friese 1896) although more recent reports may exist which could change the known northern limit.

Population [top]

Population:The species was considered very common in central Europe at the end of the 19th century (Friese 1896), particularly on roadsides and hedges (Schletterer 1895) and the specimens of this species are abundant in the ancient collections. Recently it has been found to be common only in Hungary (Jozan 2011). Today, the species is reported as rare in Spain (Ornosa 1993) and Slovenia (Anonymous 2002). It is also also threatened in the Czech Republic and Germany (Farkac et al. 2005, Westrich et al. 2008, 2011). The population trend is considered to be decreasing.
Current Population Trend:Decreasing

Habitat and Ecology [top]

Habitat and Ecology:

The species is found in Mediterranean shrublands and temperate grasslands. It is polylectic and recorded in central Europe mainly on Fabaceae species (Amiet 1994) such as Medicago sativa, Pisum sativum, Coronilla varia, Astragalus spp., Vicia spp., Trifolium spp. (Iuga 1958), Vicia varia, Vicia hybrida and Coronilla emerus (Schletterer 1895). It is also found visiting Boraginaceae such as Nonea spp. (Friese 1896), Anchusa officinalis, Cynoglossum officinale, Symphytum officinale; and on other plants including Lythrum salicaria (Lythraceae); Phlomis pungens, Nepeta cataria and Marrubium peregrinum (Lamiaceae) (Iuga 1958). 

In the Mediterranean shrubland of Croatia it is more common on Lamiaceae such as Ajuga genevensis, Thymus dalmaticus, Thymus chamaedrys, Stachys recta, Salvia bertolonii and Asteraceae (Helichrysum angustifolium) or Caryophyllaceae (Lychnis flos-cuculi) (Schletterer 1895). In Turkey it is found on Lamiaceae such as Salvia aethiopis, S. frigida, Stachys lavandulaefolia, Teucrium orientale and Asteraceae such as Carduus crispus, C. nutans, Centaurea calçitrapa, C. solstitialis, Cichorium intybus and Carduus crispus (Özbek 2010). Males of the species are also associated with the orchid Ophrys scolopax through the sexually deceptive behaviour the plant exhibits (Gaskett 2011).
