Recommendations for Maintaining a Dermestid Beetle Colony (Dermestes maculatus) for Processing Human Remains

Area of Science:

• Forensic Entomology
• Biological Anthropology
• Decomposition Studies

Background:

• Dermestid beetles (Dermestes maculatus) are utilized in forensic anthropology for tissue processing.
• Existing literature on maintaining dermestid colonies for skeletal remains processing is often outdated or lacks specificity.
• Disjointed non-academic sources hinder replication of ideal dermestid habitats and environmental conditions.

Purpose of the Study:

• To present updated, specific recommendations for establishing and maintaining Dermestes maculatus colonies.
• To provide guidance for biological anthropologists interested in using dermestids for forensic processing.
• To address the need for replicable methods in dermestid colony management.

Main Methods:

• Recommendations based on practical experience with multiple Dermestes maculatus colonies.
• Processing of five unembalmed human heads to assess colony health and maintenance.
• Detailed examination of crucial environmental factors: bedding, food, water, containment, temperature (24-27°C), and humidity (35-73%).

Main Results:

• Identified key factors for healthy dermestid colony management: appropriate bedding, food, water, and containment.
• Established optimal temperature (24-27°C) and humidity (35-73%) ranges for Dermestes maculatus.
• Demonstrated that while materials are inexpensive, colony maintenance is labor-intensive.

Conclusions:

• Establishing and maintaining Dermestes maculatus colonies requires careful attention to environmental parameters.
• The investment in dermestid colony upkeep is justified by the volume of casework requiring skeletal remains processing.
• This technical note offers a replicable framework for dermestid colony management in forensic anthropology.
