In behavioral biology, brood care refers to all behaviors of females and / or males that lead to the offspring having optimal chances of survival before oviposition or birth. The behavior of care beyond that is called brood care .

Many animals, such as B. Most insects , some fish , amphibians or reptiles do not care for the brood, i.e. care for the offspring while they are growing up or after giving birth or laying eggs. The mothers just make sure that their offspring find optimal conditions and leave them to themselves. Subsequently butterflies such place. B. their eggs on the forage plants of their caterpillars .

We find pronounced brood care e.g. B. the hazel leaf roller , the piston water beetle and dung beetles (Geotrupidae). The hazel leaf roller makes complicated leaf wraps in which it lays the eggs. The piston water beetle even builds small boats to lay eggs. With the dung beetles, the parents create species-specific duct systems in the soil, into which they also bring in food for the larvae . After laying eggs, however, they leave their brood.
