Mayflies are distributed all over the world in clean freshwater habitats, [35] though absent from Antarctica. [36] They tend to be absent from oceanic islands or represented by one or two species that have dispersed from nearby mainland. Female mayflies may be dispersed by wind, and eggs may be transferred by adhesion to the legs of waterbirds ...

It possibly originated in the Middle East, and spread around the world as a commensal of humans. It is the most common fly species found in houses.

Insect winter ecology describes the overwinter survival strategies of insects, which are in many respects more similar to those of plants than to many other animals, such as mammals and birds. Unlike those animals, which can generate their own heat internally ( endothermic ), insects must rely on external sources to provide their heat ...
Rhithrogena fradgleyi Blair, 1929. Rhithrogena germanica is a European species of mayfly, and is "probably the most famous of all British mayflies", because of its use in fly fishing. It is known in the British Isles as the March brown mayfly, a name which is used in the United States for a different species, Rhithrogena morrisoni. [3]
Unfortunately, carcasses can pile up and smell like rotting fish. A single fish fly can lay 500 to 8,000 eggs on the water surface. The fish fly season typically starts in June and can last ...
The mature adult stage of Hexagenia limbata can be as much as 27 mm (1.1 in) long. The females tend to be slightly larger than the males but have smaller eyes. The forewings are long and membranous while the hind wings are much smaller and have dark margins. The tip of the abdomen bears two long cerci or tails. When the insect is at rest, the ...
The group is sometimes referred to as flat-headed mayflies or stream mayflies. These are generally rather small mayflies with three 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.
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.
