Number of Lepidoptera and Microgastrinae species in selected areas of Canada. The figures are rounded to the nearest tenth for Microgastrinae species and to the nearest integer for the L/M ratio. For Lepidoptera the data are taken from Danks (1981) for the Arctic Archipelago; Lafontaine and Wood (1997) for the Yukon; and Lafontaine (1997) for Ottawa. Microgastrinae figures are based on the present paper and unpublished data of the author.

Area	Latitude (Area in km2)	# Lepidoptera (L)	# Microgastrinae (M)	L/M Proportion
Canadian Arctic Archipelago	>70° N (1,400,000 km2)	136	20	7
Yukon Territory	60–70° N (475,000 km2)	~2,000	120–150	13–17
Ottawa and surroundings	45° N (~8,000 km2)	2,068	150–200	10–14
