Tribe Alysiini

Hymenoptera - Braconidae? - Orthostigma - female Alysiine? ex Pegomya cf. pseudobicolor - Orthostigma Braconid ex agromyzid ex Eutrochium purpureum Dinotrema - female Alysiine head, dorsal view - Phaenocarpa Chalcid (or ichneumonid) from Eupatorium blotch mine - Glyphogaster Parasitic wasp Two wasps from a grass leaf mine - Dapsilarthra
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 Alysiinae
Tribe Alysiini
Other Common Names
3-celled jaw wasps.(1)
Pronunciation
Ah-liss-ee-EYE-nee
Numbers
about 33 genera in the New World; about 31 of these in North America.(2)
Size
1-5 mm.
Identification
Alysiini can be separated from its sister tribe by the presence of an r-m vein, sometimes faint, and veins RS and M not widely separated in basal part of wing. In contrast, Dacnusini have no r-m vein.
Range
Cosmopolitan
Habitat
Often in moist habitats and decaying substrates, where host larvae are likely to be found.
Food
Larvae are parasitoids that feed on larvae of cyclorrhaphous Diptera (advanced flies with short antennae).
Life Cycle
Adult females lay their eggs in the eggs or larvae of the host. The emerging wasp larva feeds on the host and eventually kills it after the host pupates. The wasp pupates inside the puparium of the host. When it emerges as an adult, the wasp cuts an emergence hole in the dead host's puparium with its exodont mandibles adapted specifically for this task.
