You may know this one, the Six-spotted Tiger Beetle, Cicindela sexguttata, which is common throughout Ohio. If you see an astonishingly rapid, iridescent green beetle shooting along the path ahead of you, it may be this. A close look will reveal six tan spots along the edges of the carapace.
A Hairy-necked Tiger Beetle racing along the beach. Extraordinarily wary for an insect, some patiance is required for a close approach. Around here at least, this species seems to need largely unmolested sands of Lake Erie beaches. Intense use by people undoubtedly drive it out, and that's been the fate of most Ohio beaches.
Two days later, while leading a field trip to the beach at Sheldon Marsh as part of the warbler symposium, Ben Warner and I found some Hairy-necks there. Ben, amazingly, was able to snag one. After study and photos, it was released unharmed. Sorry about the blurriness of the shot; nonstop rain that day and I couldn't keep the camera lens dry. Still, you can see the ornate markings on the upper wings that characterize tiger beetles. They can be quite difficult to spot against the sand, though.
Voracious predators, as you might deduce from the large pincers. They in turn are preyed upon by many other insects. Tiger beetles warrant monitoring, as many species seem especially vulnerable to habitat degradation.
