Eighty-two specimens (NB=6, NS=66, PE=12) were examined. The earliest records from each province are:
The dates of earliest detection are given above: New Brunswick (1939), Nova Scotia (1919), and Prince Edward Island (1954).

In general, mycetophagids have received rather little attention by researchers in North America, and the bionomics of many species have not been carefully investigated. Certainly this is true in the Maritime Provinces and additional fieldwork in the region is required to ascertain more about their distribution, abundance, bionomics, and ecological role in the habitats that they inhabit.
