Parasitoid and chalcid wasps - Chalcidoidea
Chalcid wasps (from the Latin, "chalcis" - metallic-coloured) are a very complex and species-rich group with constantly evolving taxonomy. In the UK, 1,754 recorded species were on the 2016 checklist, although this is certainly an underestimate of the total. All are endoparasitoids, the females laying eggs inside host eggs or larvae, which their larvae consume and kill. These tiny wasps often have a wide global distribution and in addition have been very widely used as biological pest control.
Chalcididae - Chalcid wasps
The family Chalcididae is a subgroup group within the superfamily Chalcidoidea. Chalcididae are generally slightly larger, sturdier and have a more "armored" appearance than other Chalcidid families. The hind femur is greatly enlarged and muscular and the hind tibiae characteristically bowed to fit snugly against the swollen femur when the leg is retracted.
