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:

  1. Rollers – roll dung into balls.
  2. Tunnelers – bury dung beneath the soil.
  3. 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.
