Subfamily Aphidiinae

Aphid? Small Wasp on Small Chamaesyce flowers Parasitic wasp with aphids - female Braconid Wasp - Monoctonus Block Island Trioxys fore wing - Trioxys - female Block Island Trioxys fore wing - Trioxys - female Aphidiinae? - Trioxys - female Aphidius? - Lysiphlebus
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 Ichneumonoidea (Braconids and Ichneumons)
Family Braconidae (Braconid Wasps)
Subfamily Aphidiinae
Synonyms and other taxonomic changes
=Aphidiidae
Numbers
~120 spp. in 16 genera in our area(1), ~400 spp. in ~50 genera worldwide
Size
~2.5 mm(1)
Identification
tiny, usually less than 3mm
fragile, metasomal tergites weakly sclerotized
antennae rather short, usually 18 or fewer segments except in some males
fore wing venation in most groups (except Toxares and Ephedrus) reduced, with no 2nd submarginal cell, and 3RSb not reaching wing margin. Click here for image of complete venation, as in Toxares and Ephedrus. Click herefor an example of incomplete venation, as in other aphidiine genera. (wing images are provided for each aphidiine genus in Bugguide. See genera under Aphidiinae, under Taxonomy, Braconidae).
occipital carina present, at least laterally (Achterberg, C. van. 1997. Subfamily Aphidiinae. In:(2)

For terminology of body parts see PDF, p. 99, Fortier 2009(3)
Range
World wide, wherever aphids are found
Food
hosts: aphids(1)
Life Cycle
Koinobiont endoparasitoids of aphids.
Remarks
Like Rogadinae, the aphidiines mummify the host and undergo pupation inside the dead host mummy. The "mummy" is the dried, hardened husk of the host remains. When the adult emerges, it cuts an escape hole in the mummy.
