Cicindela longilabris Say – Boreal long-lipped

tiger beetle (S5)

Cicindela longilabris has a typical boreal distribution, being the most northerly occurring tiger beetle in Ontario and one of the most northerly ranging tiger beetle species in North America. It is known to occur from the east coast of North America north to the Yukon, Northwest Territories, and Alaska (Pearson et al. 2015). In boreal forest, it is typically found in areas with sandy substrate (e.g., Jack pine forest), often nutrient-poor, acidic soils in or near coniferous forests (Pearson et al. 2015) .

The subspecies most commonly occurring in Ontario is C. longilabris longilabris (Pearson et al. 2015) . This species has previously been reported in Ontario north to the southern shores of James Bay and northwest to the border of Manitoba approximately 100 km southeast of Shamattawa (Pearson et al. 2015). Pearson et al. (2015) map a large gap in the range of this species in the Hudson and James Bay regions of Ontario, which we now can fill ( Fig. 7 ). Based on our collections, the range of C. longilabris is extended north by approximately 400 km to the Hudson Bay coast compared to the records included in Wallis (1961) 1.

A rare and less commonly encountered subspecies in Ontario is C. longilabris nebraskana Casey (previously considered a separate species, C. nebraskana ). This subspecies was not encountered during our surveys of northern Ontario. The single Ontario record of C. longilabris nebraskana is from near Rushing River Provincial Park in Rainy River District ( Fig. 7 ), where it was reported by Lawton (2008). Cicindela longilabris nebraskana is a western subspecies, restricted to bare soil (usually clay or black dirt patches) in grasslands with few or no trees (Pearson et al. 2015).
