Cobblestone Tiger Beetle

Cobblestone tiger beetle (Cicindela marginipennis) is a medium-sized ground beetle in the family Carabidae (tribe Cicindelini), native to riverbars and cobblestone beaches of major river systems in eastern North America, from Quebec and Ontario south through the Ohio and Mississippi river basins. It is a habitat specialist restricted to dynamic, open gravel and cobble bars on large rivers, where bare, sun-warmed substrate provides ideal conditions for hunting small invertebrate prey. Like all tiger beetles, it is a fast-running, visually acute predator that captures prey by rapid pursuit. Adults are active on sunny days from late spring through summer, capable of short bursts of flight. Cobblestone tiger beetle is assessed as Vulnerable by the IUCN due to severe declines caused by the loss of dynamic river cobblestone habitat through dam construction, channelisation, bank stabilisation, and loss of natural flood regimes that maintain bare substrate. Populations have disappeared from many historically occupied rivers. Conservation efforts focus on preserving and restoring natural river dynamics on rivers where the species persists.
