New Forest cicada  (Cicadetta montana)

Abdomen: in arthropods (crustaceans, insects and arachnids) the abdomen is the hind region of the body, which is usually segmented to a degree. In crustacea (e.g. crabs) the limbs attach to the abdomen; in insects the limbs are attached to the thorax (the part of the body nearest to the head) and not the abdomen. In vertebrates the abdomen is the part of the body that contains the internal organs (except the heart and lungs).
Nymphs: stage of insect development, similar in appearance to the adult but sexually immature.
Proboscis: a tubular protrusion from the anterior of an animal (e.g. the trunk of an elephant).
Thorax: part of the body located near the head in animals. In insects, the three segments between the head and the abdomen, each of which has a pair of legs.
