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]
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.
Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, [ 2 ] [ 3 ] in addition to over 2,000 extinct ones. [ 4 ]
Ecphylus janzeni is a small braconid wasp characterized by its slender body, segmented antennae, and distinctive wing venation patterns. The species exhibits sexual dimorphism, with females typically being larger than males.
It is among the largest of the Hymenoptera, growing up to 5 cm in length. [2] Although Hemipepsis resembles its Pepsis relatives, the latter tends to be a more metallic black with a deep-blue striped patterning. Since their biologies and appearances are similar, the only reliable way to tell them apart is by their wing venation patterns. [3]
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 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 ...
Chalcid wasps (/ ˈ k æ l s ɪ d /, from Greek khalkos 'copper', for their metallic colour) [1] are insects within the superfamily Chalcidoidea, part of the order Hymenoptera. The superfamily contains some 22,500 known species, and an estimated total diversity of more than 500,000 species, meaning the vast majority have yet to be discovered ...
