Cicindela punctulata Olivier, 1790. Adults of the punctured tiger beetle are sometimes attracted to light at night. There are over 2,600 known species in the genus Cicindela. Many are found in sandy soil (often near bodies of water). Adults often run after their prey (and some members of this genus can reach speeds of 9 km/h. When you consider their size, these are some of the fastest land animals on our planet. This specimen was collected by Mark DuBois in Peoria Co., Illinois.
Cicindela sexguttata Fabricius, 1775. The common name for this species is six-spotted tiger beetle. Adults and larvae are predators of small arthropods. These beetles are often observed along trails in wooded areas )particularly the sunny patches). Larvae hunt from burrows in sandy soil (they often lunge out of the burrow to capture passing arthropods; mostly small insects and spiders). This specimen was collected by Mark DuBois in Marshall Co., Illinois.
Patrobus longicornis (Say, 1823). This species is known from Illinois and Indiana (among other states). It is often associated with wet or moist habitats. Adults are often attracted to lights a night. This specimen was collected by Mark DuBois in Peoria Co., Illinois.
