Cicindela scutellaris
festive tiger beetle
Cicindela scutellaris, commonly known as the festive tiger beetle, is a widespread North American tiger beetle species occupying deep, dry sand habitats east of the Rocky Mountains. The species exhibits extraordinary geographic variability in coloration and maculation patterns across its range, with seven generally accepted subspecies recognized. Populations in Missouri represent a notable intergrade zone between northern and southeastern subspecies. The species is frequently associated with Cicindela formosa (big sand tiger beetle) in suitable habitats.
Cicindelidia rufiventris
Eastern Red-bellied Tiger Beetle
Cicindelidia rufiventris is a tiger beetle species found in the eastern and central United States, characterized by its distinctive red-orange abdomen visible during flight. Formerly classified in the genus Cicindela, it was moved to Cicindelidia based on phylogenetic studies. The species shows clinal variation in coloration and maculation across its range, with southern populations exhibiting blue coloration and reduced maculations. It is primarily active during summer months and is associated with rocky, open habitats in the Ozark Highlands and similar regions.
