In entomology, the term petiole is most commonly used to refer to the constricted first (and sometimes second) metasomal segment of members of the Hymenopteran suborder Apocrita; it may be used to refer to other insects with similar body shapes, where the metasomal base is constricted. Entomology (from Greek grc ἔντομος entomos, "that which is cut in pieces or engraved/segmented" hence "insect" and grc -λογία The metasoma is the posterior part of the body or tagma, of Arthropods whose body is composed of three parts the other two being the Prosoma and the Hymenoptera is one of the larger orders of Insects comprising the sawflies, Wasps Bees and Ants The name refers to Occasionally, it is alternatively called a pedicel, but in entomology, that term is more correctly reserved for the second segment of the antenna. Antennae (singular antenna) are paired Appendages connected to the front-most segments of Arthropods In Crustaceans they are

The portion of the metasoma posterior to the petiole (and postpetiole in Myrmecinae) is known as the gaster. The Myrmecinae is a subfamily in the Formicidae.Its members possess both a petiole and Postpetiole and do not enclose their young in cocoons The gaster is the bulbous posterior portion of the Metasoma found in Apocrita Hymenoptera ( Bees Wasps and Ants.

Other uses

• The term may also be used in the context of wing veins, where a wing cell that is ordinarily four-sided is reduced to a triangle with a stalk (the cell thus being petiolate). Insect wings are outgrowths of the Insect Exoskeleton that enable insects to fly.
• It is also used to refer to the stalk at the base of paper wasp nests. Paper wasps are 3/4 Inch to 1 inch (2-25 cm)-long Wasps that gather Fibers from dead wood and plant stems which they mix with Saliva
