Baetidae
Baetidae is a family of with about 900 described species distributed worldwide. 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. Most species have long oval forewings with very few cross veins (see Comstock-Needham system) but the hindwings are usually very small or even absent. The males often have very large eyes, shaped like turrets above the head (this is known as "turbinate condition"). [more]
Heptageniidae
Heptageniidae (Synonym: Ecdyonuridae) is a family of with around 500 described species with a mainly Holarctic distribution. These are generally rather small mayflies with two long tails. The wings are usually clear with prominent venation although species with variegated wings are known. As in most mayflies, the males have large compound eyes but not divided into upper and lower parts (the group is sometimes referred to as flat-headed mayflies). [more]
