Family Platygastridae

Tiny wingless wasp? - Trimorus - female wasp - Trissolcus Tiny wasp on Coreid eggs Colorado small parasitic wasp - Gryon Wasp - Trissolcus lateral, as found/in situ - Amitus Wasp - Scelio Baeus wasp - Baeus - female
Classification
Kingdom Animalia (Animals)
Phylum Arthropoda (Arthropods)
Subphylum Hexapoda (Hexapods)
Class Insecta (Insects)
Order Hymenoptera (Ants, Bees, Wasps and Sawflies)
No Taxon ("Parasitica" (parasitic Apocrita))
Superfamily Platygastroidea
Family Platygastridae
Synonyms and other taxonomic changes
Platygasteridae, Scelionidae
Subfamilies Scelioninae, Teleasinae, and Telenominae used to be treated in a separate family, Scelionidae
Numbers
almost 500 spp. in ~55 genera in our area, arranged in 6 subfamilies(1)
Size
0.45-4 mm(1)
Food
egg parasites; hosts include insects of at least 7 orders
Remarks
The mothering wasps often do stay with the parasitized eggs until they are emergent, mostly to keep other egg parasites away. They can be very common at the end of summer when egg numbers are at a peak. (Comment by Herschel Raney).
Some species are very host specific, others parasitize a wide range of hosts. Many species are used to control important pests, such as gypsy moth (Lymantria dispar), migratory locust (Locusta migratoria), Eurygaster integriceps, kissing bugs (Triatominae), and horse flies (Tabanus)
