Wētā live in New Zealand. Their name means “terrible grasshopper,” but they’re actually giant, flightless, nocturnal crickets. They live on the forest floor, and eat mostly plants. They’re really tough, and can survive being frozen solid. Their ear holes are located on their front legs, and they’re so heavy they can’t really jump. They don’t have wings, and they love carrots.

The heaviest insect on record is an Actaeon Beetle, bred in Japan in 2009, which weighed 8 oz (228 g). That was a larva, the juvenile stage of insects. The list below includes only adults. Here are the six heaviest insects that could be verified, weighed in ounces and grams:
