Which of the following is the world's longest insect, as of 2020?

Tremain White, Good question and what do they eat and fit into the insect world. Are they alien from another world ? ! ! !

I am not a number., ha haw

Arohanui, actually they are quite friendly and when you pick one up and put him on your arm he will stay there happily they don't bite ( not me anyway) 😂

Very punny

I've just 'twigged' that they are from an interesting 'branch' of the insect world.

Given we've yet to know of all members within all species existing—discovering new living forms throughout the animal kingdom—the question might be rephrased as "which is the longest known insect?"
