Giant weta

Endemic to New Zealand, giant wetas are enormous bugs that are related to crickets. The largest giant wetas can weigh in excess of 70 grams (about 2.5 ounces), making them among the heaviest insects in the world. (They can weigh more than a sparrow.)

They are long too, with bodies measuring as long as about 4 inches not including the legs and antennae.

Because these giants are only found on islands, they are an excellent example of island gigantism.
