**Necrophoresis**
**Definition**
Necrophoresis is the behavior exhibited by certain social insects, such as ants, bees, and termites, involving the removal and disposal of dead individuals from the colony to maintain hygiene and prevent disease.

### Overview
Necrophoresis is a critical hygienic behavior observed primarily in eusocial insects. When a colony member dies, other individuals detect chemical cues emitted by the corpse and promptly remove it from the nest. This behavior helps reduce the risk of pathogen spread within the densely populated colony environment.
### Mechanism
The process is triggered by the detection of specific chemical signals, often fatty acids like oleic acid, released by decomposing bodies. Worker insects respond by carrying the dead individual away from the nest, typically depositing it in designated refuse areas or burial sites. This organized removal is essential for colony health and survival.
### Ecological and Evolutionary Significance
Necrophoresis contributes to the overall fitness of social insect colonies by minimizing disease transmission. It exemplifies the complex social organization and division of labor characteristic of eusocial species. Understanding necrophoresis also provides insights into insect communication and collective behavior.

**Meta Description:**
Necrophoresis is the removal of dead individuals by social insects to maintain colony hygiene and prevent disease. This behavior is vital for the health and survival of eusocial insect communities.
