Prosopistomatidae is a family of mayflies. There is one extant genus, Prosopistoma, with several dozen species found across Afro-Eurasia and Oceania. They are noted for their unusual beetle-shaped larvae, which live beneath rocks and stones along the gravelly lower reaches of rivers.[1][2][3][4] Their ecology is unclear, but they are probably carnivorous.[4] They are closely related to Baetiscidae, with both families being placed in the Carapacea.[5]
