Biology

The species was collected from the agromyzid leafminers Liriomyza sativae, L. trifolii and Calycomyza lantanae (Hansson &
La Salle, 1996
; Noyes, 2002; 2003). No further biological information is available. This is a relatively widespread parasitoid, but it does not appear to have significant impact on host populations.

Comments

C. ambiguus may be quite easily distinguished from all the other Cirrospilus by the notauli, which curve to meet the anterior margin of axilla, rather than extending to the hind margin of mesoscutum. All other Cirrospilus have the latter character, which has generally been used as one of the main features to distinguish Cirrospilus from Zagrammosoma and Diglyphus. In the description of C. ambiguus (Hansson &
La Salle, 1996)
, the authors preferred to place this species in Cirrospilus because it doesn't have other characters usually associated with Zagrammosoma or Diglyphus : it is mainly metallic in coloration and without a vaulted vertex, while Zagrammosoma has vaulted vertex and is always non-metallic; some yellow markings are present, while Diglyphus are always completely metallic.
