A Big Cricket!

Alan Boyle writes

Is this the world's biggest bug? As with all superlatives, it depends on your definition. But the sight of a New Zealand giant weta chomping down on a carrot surely has to give you the creeps, even if it's rivaled by other giant creepy crawlies.

Known as a giant weta or wetapunga to the Maori, and as Deinacrida heteracantha to scientists — is found only in protected areas such as New Zealand's Little Barrier Island. That's where Mark Moffett, an entomologist and explorer at the Smithsonian Institution, found the specimen after two nights of searching.

"The giant weta is the largest insect in the world, and this is the biggest one ever found," Britain's Daily Mail quoted Moffett as saying. "She weighs the equivalent to three mice. ... She enjoyed the carrot so much she seemed to ignore the fact she was resting on our hands and carried on munching away. She would have finished the carrot very quickly, but this is an extremely endangered species, and we didn't want to risk indigestion."

The carrot-crunching cricket went viral today, and now questions are starting to emerge about the "biggest bug" label. The information accompanying the picture lists the insect's weight at 2.5 ounces (71 grams) and its length at 7 inches (17.8 centimeters).

Questions about biggest bug - does one determine that on weight, length, wingspan, or other criteria?
