Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. ... The name Hymenoptera refers to the wings of the insects, but the original ...
Wing structure and colouration often vary with morphs, such as in the aphids, migratory phases of locusts and polymorphic butterflies. At rest, the wings may be held flat, or folded a number of times along specific patterns; most typically, it is the hindwings which are folded, but in a few groups such as the vespid wasps, it is the forewings.
Hymenoptera Hymenopterida is a superorder of holometabolous (metamorphosing) insects . As originally circumscribed, it included Hymenoptera and the orders in Panorpida ( Mecoptera , Siphonaptera , Diptera , Trichoptera and Lepidoptera ). [ 1 ]
The minute Hymenoptera are best collected by beating into, and sweeping with, a net made of fine gauze, and Mr. Haliday recommends me to collect them in quills, and afterwards to empty their contents into hot water, by which means their wings are naturally expanded; then by introducing a card under them to take them out of the water, arranging ...
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 ...
Holometabolism stages in Hymenoptera. The Endopterygota are distinguished from the Exopterygota by the way in which their wings develop. [citation needed] Endopterygota (literally "internal winged forms") develop wings inside the body and undergo an elaborate metamorphosis involving a pupal stage. Exopterygota ("external winged forms") develop ...
Neoptera (Ancient Greek néos ("new") + pterón ("wing")) is a classification group that includes most orders of the winged insects, specifically those that can flex their wings over their abdomens. This is in contrast with the more basal orders of winged insects (the " Palaeoptera " assemblage), which are unable to flex their wings in this way.
Two constants, found in nearly all insect wings, are the claval (a flexion line) and jugal folds (or fold line), forming variable and unsatisfactory boundaries. Wing folding can be very complicated, with transverse folding occurring in the hindwings of Dermaptera and Coleoptera, and in some insects, the anal area can be folded like a fan.
