Conteúdo: 	Seed-sucking hemipterans include members of several families, the most, common being Alydidae, Coreidae, Lygaeidae, Pentatomidae, Pyrrhocoridae, Rhopalidae and Scutelleridae. Several studies have stressed the biology of eggs of these bugs, including description of egg structures, embryonic development and orientation, function and shape of egg bursters, hatching rhythm and mechanisms of hatching, among others. Seed-sucking bugs are known to lay eggs in different patterns, such as in egg masses of variable number of eggs/mass or singly. These two different and contrasting ways of egg laying implicate in variable risks and benefits, in particular to first instar nymphs, which will in consequence influence  the bug's fitness. In this article these two egg deposition patterns are analyzed and discussed including possible adaptative advantages for laying eggs in groups, when first instar nymphs stay on or around egg shells, or singly, when first instar nymphs abandon the egg shell immediately after emergence.
