The Most Incredible Insects

The Most Annoying Insect: Many would agree that it is the tiny biting fly known as a "punkie" or "no see-um, " so small it can fly through the fine screening of a door or window.

The Most Beautiful Insect: Widely accepted to be the Sunset Moth from Malagasy (Madagascar), a day-flying moth of rainbow colors.

The Most Bizarrely-shaped Insect: Arguably, various species of treehoppers, Family Membracidae (Homoptera), with incredible structures that resemble thorns and barbs on their pronota (backs). Others with odd shapes are violin beetles and giraffe weevils.
