The intermittent moment when the scarabs stuck in the muck find themselves beneath their rolling ball is a dream. They themselves perceive the phenomenon as if, from time to time, a concrete slab were coming over their eyes. When the concrete slab pulls away from their eyes, the scarabs wake up.
The common denominator among most deposits of fossil insects and terrestrial plants is the lake environment. Those insects that became preserved were either living in the fossil lake (autochthonous) or carried into it from surrounding habitats by winds, stream currents, or their own flight (allochthonous).
This generally produces less power and is less efficient than asynchronous muscle, which accounts for the independent evolution of asynchronous flight muscles in several separate insect clades. [3] Insects that beat their wings more rapidly, such as the bumblebee, use asynchronous muscle; this is a type of muscle that contracts more than once ...
Several ancient civilizations considered the insect to have supernatural powers; for the Greeks, it had the ability to show lost travelers the way home; in the Ancient Egyptian Book of the Dead the "bird-fly" is a minor god that leads the souls of the dead to the underworld; in a list of 9th-century BC Nineveh grasshoppers (buru), the mantis is ...
Hymenopterans range in size from very small to large insects, and usually have two pairs of wings. Their mouthparts are adapted for chewing, with well-developed mandibles (ectognathous mouthparts). Many species have further developed the mouthparts into a lengthy proboscis , with which they can drink liquids, such as nectar .

Insect wings are adult outgrowths of the insect exoskeleton that enable insects to fly. They are found on the second and third thoracic segments (the mesothorax and metathorax ), and the two pairs are often referred to as the forewings and hindwings , respectively, though a few insects lack hindwings, even rudiments.
In contrast to the flies, the Strepsiptera bear their halteres on the mesothorax and their flight wings on the metathorax. [45] Each of the fly's six legs has a typical insect structure of coxa, trochanter, femur, tibia and tarsus, with the tarsus in most instances being subdivided into five tarsomeres. [34]
