Heteroptera is a very diverse group. Some curiosities about different groups are:
-Sphaerodema sp. males carry the eggs on their backs until they are hatched.
-Gerris sp. (the water skaters) are able to walk on water due to their long, hydrophobic legs and bristle fringes creating buoyancy for them to float.
-Pentatomidae (stink bugs) are able to eject a jet of stinking liquid to a distance of up to 50 cm.
