This is our smallest Sphecodes species and also one of the more easily-encountered ones. It usually only measures 6-8mm and has the typical black thorax, head and legs with a red and black abdomen. Accurate identification requires analysing a specimen under a microscope, but their diminuitive size is usually a useful clue. The primary host in Ireland appears to be Lasioglossum leucopus. It may also use Lasioglossum nitidiusculum, L. cupromicans or L. smeathmanellum.

Distribution in Ireland: Widespread in Ireland, but patchier in the midlands, west and north of the island.

Flight Period: Females fly between April-September, whilst males are active between June-August.

Habitat: A wide range of habitats including brownfield sites, coastal cliffs, dunes, meadows and gardens.

Flowers visited: Yarrow, dandelions, hawkweeds, Wild Carrot, mayweeds and others.

Personal Records: I have recorded this species at a number of sites, including Killard Point, Sprucefield and Bloody Bridge (all Co. Down), as well as Bonny Glen (Co. Donegal) and Armagh City (Co. Armagh). It is best searched for around bare soil banks where Lasioglossum nesting aggregations occur. This species is frequent in Ireland and possibly the commonest Sphecodes species.
