Species Biology
Identification
- Body length: 8-14mm, males smaller than females
- Head black with small yellow facial spots
- Thorax primarily black with yellow collar and yellow spot (scutellum)
- Abdomen also primarily black but with three yellow bands, the first of which is sometimes broken
- Legs reddish
- Easily confused with species such as Ancistrocerus trifasciatus and particularly Nysson spinosus. The use of a microscope and specialist keys will be required to separate it from the latter species in most cases
Habitat
Associated with deciduous woodlands in Ireland, particularly sunny clearings and glades. It can also be found in scrubby areas and has been recorded from sandy heathland. It possibly requires the presence of dry clay banks for nesting.
Flight period
In Ireland, it is stated to fly from June-August. It is likely in flight before this, in May or even April.
Nesting biology
No information on the nesting habits of this species in Ireland is available. In Britain, it constructs solitary burrows in dry clay banks in sunny woodland localities. The female stocks the burrow with froghopper nymphs before laying an egg in each of the cells she has constructed. The egg will hatch and the wasp larvae feed on the deposited froghopper larvae before pupating and emerging as adults the following year.
Flowers visited
Fly Orchid (Ophrys insectifera)*, Hogweed (Heracleum sphondylium) , Cow Parsley (Anthriscus sylvestris) and probably various Spurges (Euphorbia sp.) among others.
*The males are reportedly important pollinators of the Fly Orchid.
Native region
Europe, Temperate Asia
