Insect-dung Interactions Flashcards
Coprophagy insect taxa
Coleoptera -Scarabaeidae -Hydrophilidae Diptera -Muscidae
Challenges of copraphagy
Dung randomly deposited
-hard to find regularly
Desiccation
-utilize before dung dries
Dung utilization methods
Endocoprids - egg inside dung pad
Paracoprids - tunnel underneath Pad and bury on site
Telecoprids - dung rolled away from food source
- brood balls (formed by fertilized females)
- food balls (males and females)
Kleptocoprids
Dung beetle life cycle
Holometabolous
Feeding of dung beetles
Poorly understood
Food resource cannot be quantified
Highly specialized mouth parts
Don’t masticate
Importance of d beetles
Supporting service - improved soil fertility
Regulating service - bioturbation = no floods and disease regulation (no breeding media for pests)
Provisioning service - bury cow dung = healthy meat
Cultural service - aesthetic, spiritual and educational
Secondary seed dispersal
Pollination - Aracaea
Sanitation (human endoparasites)
Beetle diversity importance
Uniform dung dispersal
Dependable activity through the year
