Superworms could replace beetles for cleaning skeletal remains
Summary
Researchers tested using superworm larvae to clean bones for museums and studies. They found that superworms can remove soft tissue efficiently without damaging the bones and pose less risk of infestation compared to beetles.Key Facts
- Cleaning bones is important for museum displays and forensic analysis to remove all flesh carefully.
- Current methods include burial, enzymes, chemicals, or beetle larvae called dermestid beetles.
- Dermestid beetles clean well but can escape and cause infestations, harming collections.
- Superworm larvae (Zophobas morio) were tested as an alternative since only the larval stage is needed and easier to control.
- The team cleaned various animal specimens by placing them in containers with superworms, dosing larvae based on specimen size.
- Superworms do not pupate in crowded conditions, lowering the risk of escapes and infestations.
- Larvae were fed fruits or vegetables to maintain health during cleaning.
- After cleaning, skeletons were rinsed, sometimes lightly bleached (although this can harm bones), and coated with varnish for display.
