Ga. beetle reinvents the wheel | savannahnow.com
"Wheels are a common enough way for people to get around. But for animals, not so much.That’s why Georgia Southern University associate professor of biology Alan Harvey took note when a graduate student mentioned she’d seen tiger beetle larvae rolling across the beach on Cumberland Island."“Clearly this was a remarkably rare form of locomotion,” Harvey said."
Rotating at 20-60 times per second, the beetle larvae reportedly were timed at almost 7 mph, “...faster than any other insect recorded on the ground.”
“The discovery is even more remarkable because it comes in one of the best studied insects in North America. That’s part of what delights Harvey about the finding. “If we can find this out about a well-studied insect, imagine what’s out there waiting for people to learn,” he said.”
