Parasitica, Ichneumon
wasps, Ichneumonidae
Hymenoptera. The bees, bumblebees, ants, wasps and saw flies belong to that
order.
Hymenoptera is divided into different subordes. Namely suborder Symphyta
(This group has no waist, sawflies) and
suborder Apocrita. Apocrita is also divided into two groups. Namely: Parasitica and
Aculeta.
Parasitica: wasps or parasitic hymenoptera. The females have an ovipositor, with
the ovipositor they lay eggs into or near larvae. These larvae are eaten by the wasp larvae. There are several families.
The largest group are the ichneumon wasp (Ichneumonidae). Other groups are: Braconidae,
chalcid wasps (Chalcidoidea), Gasteruptiidae, gall wasps (Cynipoidea). The plant
galls of gall wasps develop, when the eggs are laid.
Aculeata: In this group the ovipositor is is modified into an
stinger. With this stinger they can defend themselves (bees) or they can
stun a prey. In this group are also wasps with parasitic larvae. Spider
wasps look like ichneumon wasps, but have a sting to stun their hosts.
Jewel wasps (Chrysididae) have a sting too.

Ichneumon wasps, Ichneumonidae
There are many species in the world. (60.000 species worldwide) Ichneumon
wasps are parasitoids of other insects. Their abdomen is very
elongated and have long antennae (at least 16 segments)
They are solitary. There are many subfamilies.
