Ecological Role
As members of Tachinidae, Clairvillia function as , likely targeting other insects. The specific remain undocumented, but related Phasiinae frequently parasitize Hemiptera or Orthoptera.

Taxonomic history
The has remained relatively stable since its description, though have been transferred in and out. Reinhard described three species (C. amicta, C. curialis, C. biguttata as combination) in the mid-20th century, suggesting renewed taxonomic attention during that period.
