Species Biology

Identification

  • Body length: 4-9mm (females larger than males)
  • Primarily black in colour with yellow legs markings
  • Relatively broad body shape
  • Square-ish head shape
  • Easily confused with other small, black solitary wasps and the use of a microscope and specialist keys is usually required

Habitat

Poorly known in Ireland. Existing records are from areas of  woodland, riverbanks and grassland.

Flight period

Univoltine, flying between June-July in Ireland, although it may fly from late May-August here as it does in Britain.

Nesting biology

Unknown in Ireland, but elsewhere nests are constructed solitarily in level, bare soil. The nest tunnel descends vertically for about 10cm, with cells constructed along this section. These cells are stocked with small paralysed Mirid bugs, on which the female will lay an egg. The hatched wasp larvae will consume the paralysed prey before pupating and emerging as adults the following year. 

Flowers visited

None known in Ireland, but elsewhere it visits composite flowers such as Yarrow (Achillea millefolium), Ox-eye Daisy (Leucanthemum vulgare), Tansy (Tanacetum vulgare) and Mayweeds (Anthemideae).

Similar species

  • Other small, black solitary wasps, such as Crossocerus
