A photo of a brown and tan Mayfly from the side. The mayfly's body is arched, the abdomen pressed to the surface it rests on, the head held high above. The head is dark brown and mostly eyes, the wings are transparent, and the rest of the body is brown and tan.
A close up of the head of the mayfly showing the three kinds of eyes. The tiny glossy ocelli are at the front of the head. The compound eyes which are mottled gray with a brown stripe through. Above those are large dome shabed brown turbinate eyes.

One of this year's joys was learning about the weirdness that are #Mayflies eyes. Some male mayflies have "turbinate" eyes or basically a third type of eye that look like hats above their other eyes that look upwards.
EYES THAT ARE HATS.
