True bugs

Pentatomidae, Greek pente meaning five and tomos meaning section, are a family of insects belonging to order Hemiptera including some of the stink bugs and shield bugs.

The scutellum body is typically half of an inch long, green or brown color, usually trapezoidal in shape, giving this family the name "shield bug". The tarsi are 3-segmented. The forewings of stink bugs are called hemelytra, with the basal half thickened while the apex is membranous (as are the hindwings).

The stink bug derives its name from an unpleasant scent from a glandular substance released from pores in the thorax when disturbed. The chemicals involved include aldehydes, making the smell similar to that of coriander. In some species the liquid contains cyanide compounds and a rancid almond scent, used to protect themselves and discourage predators.

The term 'stink bug' is also used in referring to the distantly-related species Boisea trivittata and to some unrelated insects, including beetles in the genus Eleodes such as the Pinacate beetle.

The cicadas (/sɪˈkɑːdə/ or /sɪˈkeɪdə/) are a superfamily, the Cicadoidea, of insects in the order Hemiptera (true bugs). They are in the suborder Auchenorrhyncha,[a] along with smaller jumping bugs such as leafhoppers and froghoppers.

Cicadas have prominent eyes set wide apart, short antennae, and membranous front wings. They have an exceptionally loud song, produced not by stridulation, but by vibrating drumlike tymbals rapidly. They typically live in trees, feeding on sap, and laying their eggs in a slit in the bark. Most cicadas are cryptic, singing at night to avoid predators. The periodic cicadas spend most of their lives as underground nymphs, emerging only after 13 or 17 years, which may reduce losses by starving their predators and eventually emerging in huge numbers which overwhelm and satiate any remaining predators.
