Quedius spelaeus
Spelean Rove Beetle
A troglophilic rove beetle found in porcupine dung caves in Nova Scotia, where it functions as the dominant invertebrate predator. The pupal stage was described for the first time from Nova Scotian populations. Late-instar larvae excavate and occupy cavities within dung deposits, pupating in these constructed chambers. The species shows an apparently disjunct distribution pattern in Nova Scotia, possibly reflecting post-glacial colonization from Atlantic refugia.
