Baetidae is a family of mayflies with about 1000 described species in 110 genera distributed worldwide. [1] These are among the smallest of mayflies, adults rarely exceeding 10 mm in length excluding the two long slender tails and sometimes much smaller, and members of the family are often referred to as small mayflies or small minnow mayflies.
