Scientific Name: Nomada armata

Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2013
Date Assessed: 2013-07-10
Assessor(s): Smit, J.
Reviewer(s): Roberts, S., Nieto, A. & Scott, J.A.
Contributor(s): Schwarz, M.
Justification:
Global and European regional assessment: Near Threatened (NT)
EU 27 regional assessment: Near Threatened (NT)

Listed as Near Threatened because, in spite of its wide distribution, the area of occupancy (AOO) is 696 km2, and there is a continuing decline in the extent and quality of the habitat and the number of mature individuals due to changes in agricultural practice (particularly through intensification in the use of grasslands) which have reduced the area of suitable habitat and floral resource availability for the host (meeting VU B2b(iii)). In addition this species is in significant decline (but at a rate between 10-20% in the past ten years), inferred from the degradation of its habitat.

Population [top]

Population:

The species is rare and the population trend of the species is decreasing. This species is in significant decline inferred by the degradation of the habitat, though the decline is probably less than 30% in the past ten years (J. Smit pers. comm. 2013).

Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology:

The habitats of this species are extensively used grasslands, grasslands, dikes along rivers and calcareous grasslands (Westrich 1989, Peeters et al. 2012). Nomada armata is a brood parasite and the host is Andrena hattorfiana. The host flies especially on Knautia arvensis and Scabiosa columbaria. The species is univoltine: the generation length of this species is one year (it is active from mid May until the end of July).


Systems: Terrestrial

Use and Trade [top]

Use and Trade: This species is not traded or exploited commercially.

Threats [top]

Major Threat(s):

Changes in agricultural practice (particularly through intensification in the use of grasslands) have reduced the area of suitable habitat and floral resource availability for the host.

Conservation Actions [top]

Conservation Actions:

This species is included in the National Red Lists or Red Data Books of the following eight European countries / regions: Finland (Endangered; Rassi et al. 2010); Germany (Endangered; Westrich et al. 2011); Netherlands (Endangered; Peeters and Reemer 2003); Norway (Regionally Extinct; Kålås et al. 2010); Slovenia (Endangered; Anonymous 2002); Sweden (Endangered; Gärdenfors 2010); Switzerland (Vulnerable; Amiet 1994); Great Britain (Endangered; Shirt 1987).  

The species is present in protected areas.

Conservation actions are needed to protect the areas where the species occurs.
