Everything about Petiole Insect totally explained
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. Occasionally, it's alternatively called a
pedicel, but in entomology, that term is more correctly reserved for the second segment of the
antenna.
The portion of the metasoma posterior to the petiole (and
postpetiole in
Myrmecinae) is known as the
gaster.
Other uses
- The term may also be used in the context of wing veins, where a wing cell that's ordinarily four-sided is reduced to a triangle with a stalk (the cell thus being petiolate).
- It is also used to refer to the stalk at the base of paper wasp nests.
