The warehouse beetle (Trogoderma variabile) is one of about 1,700 species in the family Dermestidae, which are scavengers that are important as grain pests, ecosystem recyclers, and forensic tools. A new, robust molecular and morphological analysis of beetles in the family Dermestidae improves understanding of the group’s evolutionary relationships—valuable knowledge for pest management, trade regulations, and forensic entomology.
