Dung Beetle
Why in News?
A study found that Onthophagus orpheus showed a strong preference for dog dung over cow dung, but this preference could have negative consequences for offspring survival.
Classification
- Family: Scarabaeidae
- Order: Coleoptera
Types
Three broad behavioural groups:
- Rollers – roll dung into balls.
- Tunnelers – bury dung beneath the soil.
- Dwellers – live within the dung.
Ecological Importance
Dung beetles:
- Recycle nutrients
- Improve soil fertility
- Aerate soil
- Assist seed dispersal
- Remove animal waste
- Reduce breeding grounds for some parasites and flies
Interesting Fact
Some dung beetles use the Milky Way and celestial cues for navigation while rolling dung balls.
New Concern
Dog faeces may contain residues of antiparasitic medicines, potentially affecting dung beetle larvae.
Prelims Trap:
