Superworms could replace beetles for cleaning skeletal remains
Preparing skeletal specimens for display in museums or for forensic studies requires the bones to be thoroughly cleaned to remove any remaining flesh or soft tissue. However, the need for thorough cleaning must be balanced against the risk of damaging the actual bones. According to a new paper published in the journal PLoS One, the larvae of so-called “superworms” (Zophobas morio)—a common pet food—offer a practical alternative.
There are existing methods for cleaning skeletal remains, such as burial, digestive enzymes, or chemical treatments. But most have drawbacks, including damaging bones, taking a long time to process, having expensive operational costs, or the use of environmentally hazardous substances. Using dermestid beetles has become the preferred method for skeletal cleaning since they can efficiently remove soft tissue without damaging the bone. The downside is that without strict containment practices, the beetles can escape and lay eggs that hatch, leading to...
