Information about Petiole (insect)

Enlarge picture
The petiole of this ant consists of two segments
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 is alternatively called a pedicel, but in entomology, that term is more correctly reserved for the second segment of the antenna.

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).
  • It is also used to refer to the stalk at the base of paper wasp nests.
Entomology, from the Greek: entomo-/εντομο- "that which is cut in pieces or engraved/segmented", hence "insect"; and logos/λόγος, "knowledge",[1] is the scientific study of insects.

Antennae (singular antenna) are paired appendages connected to the front-most segments of arthropods. In crustaceans, they are biramous and present on the first two segments of the head, with the smaller pair known as antennules.

Insect wings are 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

Paper wasps are 3/4 inch to 1 inch (2-2.5 cm)-long wasps that gather fibers from dead wood and plant stems, which they mix with saliva, and use to construct water-resistant nests that appear to be made of gray or brown papery material.
