Amblycheila cylindriformis
Great Plains Giant Tiger Beetle
Amblycheila cylindriformis is a flightless tiger beetle native to the Great Plains of North America. It is the largest tiger beetle species in North America, with adults reaching 25–38 mm in length. The species is strictly nocturnal and inhabits grassland environments, where adults walk on bare ground and larvae construct deep burrows in specific soil types.
Cicindela purpurea hatchi
Hatch's Tiger Beetle
Cicindela purpurea hatchi is a subspecies of the purple tiger beetle endemic to western North America, particularly in intergrade zones with the nominate subspecies in the Great Basin and Rocky Mountain regions. Adults exhibit the characteristic spring-fall life history of the Cicindela purpurea complex, emerging in fall as sexually immature adults, overwintering in burrows, and re-emerging in spring to mate and oviposit. The subspecies shows color polymorphism including green and black morphs, with black morphs occurring at lower frequency than in the nominate subspecies C. p. audubonii.
