scientific name    Exetastes syriacus    

habitat
Dry habitats, in weedy waste areas (Townes & Townes 1978).

seasonality
Most specimens have been collected from late spring to fall (Townes & Townes 1978).

identification
Head, thorax and antennae black. Scutellum white in males, reddish in females. Legs and gaster entirely reddish-brown in females. Males are similar except the hind legs have the apical half of the tibia and the basal two tarsal segments dark brown to black, while tarsal segments 3 and 4 are white.

life history
The small number of mid-summer collections (compared to spring/fall collections indicates this species may have two generations per year (Townes & Townes 1978). Specimens have been collected from flowers of wild parsnip (Pastinaca sativa), phacelia (Phacelia sp. ), rubber rabbitbrush (Chrysothamnus nauseosus speciosus) and Russian thistle (Salsola pestifer) (Townes & Townes 1978), as well as from alfalfa (Medicago sativa). See Exetastes genus page for general life history.

conservation
No information available.

diet info
No host records. Host is probably Lepidoptera: Noctuidae.

range
Holarctic. North American specimens have been collected from the western half of North America, as well as from Michigan and New York.

notes
Synonym Exetastes ruficoxalis Cushman. Holarctic distribution, lack of close relatives in North America and association with weedy habitats suggest this species may be introduced to North America (Townes & Townes 1978).
