Sharpshooter leafhopper (Cicadellidae: Cicadellinae: likely Proconiini) from Monteverde, Costa Rica.
Delphacid planthopper (Delphacidae) from Iowa, USA. This odd-looking little fellow is actually a mature adult, as the wings are significantly reduced (brachyptery) in some members of this family.
Cute little spittlebug (Clastopteridae: probably Clastoptera funesta) from Monterverde, Costa Rica. It's difficult to see from his angle, but this species has a very convincing "false face" on its backside to fool predators into attacking less vital areas of its body.
