Cicindela denikei Brown – Laurentian tiger

beetle (S3S4)

Cicindela denikei , originally described from Ingolf in northern Ontario by Brown (1934), is a globally rare (G3G4) tiger beetle, whose world distribution is largely restricted to a small area of northwestern Ontario, southeastern Manitoba, and northern Minnesota (Kaulbars and Freitag 1993a). Although it has sometimes been treated as a subspecies of C. sexguttata (e.g., Wallis 1961), it is now generally treated as a full species (e.g., Freitag 1999; Bousquet et al. 2013; Pearson et al. 2015). Cicindela denikei is restricted to boreal forest, typically on sandy soils among granite outcrops of the Canadian Shield (Pearson et al. 2015).

A highly disjunct population occurs on alvars on Manitoulin Island ( Bouchard et al. 2005). Brust (2007) added additional records from northwestern Ontario and Kaulbars and Freitag (1993b) and Brust (2007) provided information on the behavior of this species. Our records from the Rainy Lake area of Rainy River District are southeast of the range mapped by Wallis (1961) but within the shaded distribution mapped by Pearson et al. (2015) ( Fig. 2 ).
