The epicuticle which is a thin waxy water resistant outer layer and contains no chitin and the layer under it called the procuticle. The apocrita have a common evolutionary ancestor and form a clade.

Occasionally some species such as yellowjackets. The body of an insect is does not mature like the body of a human does. Notoauli deep and straight.
