Dung Beetles (superfamily Scarabaeoidea) rolling and fighting over dung ball, sequence, Kenya

In an experiment, nearly 4,000 beetles arrive within 15 minutes of dung appearing. An hour later, most dung is buried or dispersed. The most effective method is ball rolling, which must be done quickly to avoid theft. Some beetles carry dung in jawfuls, but ball rolling is more efficient, akin to packing a trunk.

How many beetles arrived within 15 minutes of the dung appearing in the experiment?

• 1,000

• 2,000

• 3,000

• 4,000

What is the most effective method of dung dispersal according to the video?

• Burying dung

• Ball rolling

• Carrying dung in jawfuls

• Leaving dung in place

Why must beetles work quickly when using the ball rolling method?

• To prevent the dung from drying out

• To avoid being caught by predators

• To ensure the dung is buried deeply

• To avoid theft from other beetles

What is a less efficient method of dung dispersal mentioned in the video?

• Leaving dung in place

• Carrying dung in jawfuls

• Burying dung

• Ball rolling

How is ball rolling compared to other methods of dung dispersal?

• It is less effective than carrying dung in jawfuls

• It is slower but more thorough

• It is only used by a few beetles

• It is the most efficient method
