Abstract

The oedemerid beetle, Ditylus caeruleus, is recorded for the first time from Mar- quette County, Michigan. Bionomical data associated with the specimens represent the first such information for this species. Eight additional new Michigan county records for the species are also reported, including the first specimens from the Lower Peninsula. The distributional range of caeruleus is highly correlated with the Great Lakes, the 81. Lawrence River, and coastal Maine. Implications of this distribution pattern relating to possible development of larvae in driftwood and the potential significance of rafting as a dispersal mechanism are also discussed.
