Wing venation patterns are otherwise highly variable. The antennae typically have 16 segments or more; the trochanters have two segments. Females often have long ovipositors, an organ that largely varies interspecifically. This variation is closely related to the host species upon which the wasp deposits its egg.
The main veins and the crossveins form the wing venation pattern. The venation patterns are different in different species. There may be very numerous crossveins or rather few. The Australian Flatwing Damselfly's wings are one of the few veins patterns. The venation pattern is useful for species identification. [49]
Ichneumonids are distinguished from their sister group Braconidae mainly on the basis of wing venation. The fore wing of 95% of ichneumonids has vein 2m-cu (in the Comstock–Needham system), which is absent in braconids. Vein 1rs-m of the fore wing is absent in all ichneumonids, but is present in 85% of braconids. In the hind wing of ...
The two families are unified by several characters, the most visible of which is their wing venation is greatly reduced in a very specific and unique way; the costal and radial veins have fused so no costal cell is present, a short break occurs at the stigma, and the only vein in the wing membrane itself is the radial sector, which is short and ...
The wing venation is the most complete among Hymenoptera: Only in Xyelidae the radial sector Rs furcates into the veins Rs1 and Rs2, while in other Hymenoptera Rs1 is absent. The females bear a more or less long ovipositor, which in some species of Xyela may be as long as the body. Morphology of the ovipositor and the ovipositor sheath are ...
