Explanation of Names
Greek chalkos 'bronze, copper' - a reference to metallic color
"chalcid" [KAL-sid] (not chalcidid) is the correct way to refer to a member of the group; "chalcidian" is a synonym of "chalcid" (Webster's Unabridged Dictionary 1983)
Numbers
>140 spp. in 15 genera of 4 subfamilies in our area and ca. 1500 spp. in ~90 genera of 5 subfamilies worldwide(1)
Size
2.5-9.0 mm(1)
Food
hosts: mostly Lepidoptera and Diptera, though a few attack Hymenoptera, Coleoptera or Neuroptera(1). Parasites of Lepidoptera usually attack young pupae, while those of Diptera attack mature larvae.(2)
Remarks
The terms "chalcid" and "chalcid wasp" typically refer to the whole superfamily Chalcidoidea, so it is best to use "chalcidid" when specifically referring to this family.
