Violet Dropwing Trithemis annulata

Males of this African and Middle Eastern dragonfly are stunningly violet-red with matching veins in their wings, while females are dull yellow and brown—complete opposites in a remarkable display of sexual dimorphism. Both share brilliant red eyes that make them instantly recognizable. The "dropwing" part of the name comes from a characteristic behavior: immediately after landing, they lower their wings downward, a distinctive pose that signals they've found a perch.
