The insect body is divided into three parts: the head, thorax, and abdomen. [2] The head is specialized for sensory input and food intake; the thorax, which is the anchor point for the legs and wings (if present), is specialized for locomotion; and the abdomen is for digestion , respiration , excretion , and reproduction.
In hymenopterans of the suborder Apocrita (wasps, bees and ants), the mesosoma consists of the three thoracic segments and the first abdominal segment (the propodeum). For historical reasons, in ants it is commonly referred to by the alternative name alitrunk .
Sphex ichneumoneus, known commonly as the great golden digger wasp or great golden sand digger is a wasp in the family Sphecidae. It is identified by the golden pubescence on its head and thorax, [ 2 ] its reddish orange legs, and partly reddish orange body. [ 3 ]
Many insects can hear, using tympanal organs, which may be on the legs or other parts of the body. Their sense of smell is via receptors, usually on the antennae and the mouthparts. Nearly all insects hatch from eggs. Insect growth is constrained by the inelastic exoskeleton, so development involves a series of molts. The immature stages often ...
The main function of insect blood, hemolymph, is that of transport and it bathes the insect's body organs. Making up usually less than 25% of an insect's body weight, it transports hormones, nutrients and wastes and has a role in osmoregulation, temperature control, immunity, storage (water, carbohydrates and fats) and skeletal function.

The flowers of Cryptostylis orchids and female wasp body parts are very similar in colour when viewed under a hymenopteran visual system, despite looking unlike to human eyes. Although the colours that ichneumon wasps see are unknown, bees and wasps have similar perception with green, blue and ultraviolet wavelengths. [6]
Viktor Stepanovich Grebennikov (Russian: Виктор Степанович Гребенников; 23 April 1927 in Simferopol – 2001 in Novosibirsk) was a self-proclaimed Russian scientist, biologist, entomologist and paranormal researcher best known for his claim to have invented a levitation platform which operated by attaching dead insect body parts to the underside.
