While "fly" is part of the common name, chalcid flies are not true flies (order Diptera). They are tiny wasps (order Hymenoptera). Their defining ecological role is as parasitoids, meaning their larvae ultimately kill their host insect, which differentiates them from parasites that do not necessarily kill the host.
