The heaviest insect in the world is the Goliath Beetle. It is found most commonly in tropical African rainforests, but can also survive in many other areas of Africa. Their size does vary with species. The largest species is "Goliathus goliath", weighing on average, 3.5 ounces (nearly 100 grams).
I am willing to bet that you are speaking in terms of arthropods, including insects, arachnids, and other invertebrate orders, and, under that assumption, i give to you Cyanea capillata, or the lion's mane jellyfish. It can grow up to 150 feet long (tentacles) and up to nine feet wide (bell).
The name of the biggest bug in the world is the Giant Weta.The thing is SO huge it can eat an ENTIRE CARROT.The majority of the bug's wingspan is 7 inches long,pretty big for an insect!The Giant Weta is really only found of Little Barrier Island in New Zealand.The island actually helps the Giant Weta grow to a monstrously large size due to the fact there are fewer predators in it's habitat.I've never seen one live and up close,but I HAVE seen pictures(good pictures)so take it from me these things are Huge!
