Common Name: mayflies

Mayflies are easily recognized by their 2 or 3 tails and the large forewings that are held clasped together up above the body. The hindwings are small or absent. The two photos here show an adult male burrowing mayfly and a subimago female baetid mayfly. Mayflies are the only winged insects with a winged sub-adult stage, or subimago.
