Environmental archaeology, which emerged in the 1970s, explores how past communities lived with and shaped their surroundings. By combining methods from paleoecology, biology, geology, and other natural sciences, researchers can reconstruct ancient landscapes, climate conditions, and the environmental setting of archaeological sites.
Within this field, beetles have become especially powerful clues. Because many species are highly sensitive to temperature, moisture, and habitat disturbance, their remains help scientists infer past environmental conditions. Their tough chitinous shells preserve well, offering insight into everything from diet and sanitation to storage practices and even burial customs. Archaeoentomologists use targeted sampling to recover these tiny beetle body fragments, and specialists identify them in the lab using morphological keys and comparative collections.
Some beetles point to very specific conditions, such as species associated with stored grain, while others reflect broader ecological settings, like those that feed on decaying organic matter. As a result, archaeoentomology provides both direct evidence of past environments and indirect evidence of human behaviour, especially valuable at sites where artifacts are scarce or poorly preserved.
Shown here are subfossil (organic remains that have not fully fossilized) beetle fragments (head, pronotum, and elytra) from Kivalekh in northern Labrador, the largest known Inuit winter settlement. Both specimens belong to the rove beetle family but represent different species: Holoboreaphilus nordenskioeldi (left) and Olophrum boreale (right). These species were identified in Labrador for the first time, giving researchers a clear timeline for their presence (mid‑15th to early 17th century, based on radiocarbon dating). Although both are native Holarctic species, their abundance and the overall beetle assemblage suggest synanthropic behaviour - species drawn to human settlements, likely attracted by organic waste.
