Heptageniidae
The Heptageniidae (synonym: Ecdyonuridae) are a family of mayfly, mayflies with over 500 described species mainly distributed in the Holarctic, Oriental, and Afrotropical regions, and also present in the Central American Tropics and extreme northern South America. Description 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. Heptageniids breed mainly in fast-flowing streams, but some species use still waters. The nymph (biology), nymphs have a flattened shape and are usually dark in colour. They use a wide range of food sources with herbivore, herbivorous, scavenger, scavenging, and predation, predatory species known.

Mayfly
Mayflies (also known as shadflies or fishflies in Canada and the upper Midwestern United States, as Canadian soldiers in the American Great Lakes region, and as up-winged flies in the United Kingdom) are aquatic insects belonging to the order Ephemeroptera. This order is part of an ancient group of insects termed the Palaeoptera, which also contains dragonflies and damselflies. Over 3,000 species of mayfly are known worldwide, grouped into over 400 genera in 42 families. Mayflies have ancestral traits that were probably present in the first flying insects, such as long tails and wings that do not fold flat over the abdomen. Their immature stages are aquatic fresh water forms (called "naiads" or "nymphs"), whose presence indicates a clean, unpolluted and highly oxygenated aquatic environment. They are unique among insect orders in having a fully winged terrestrial preadult stage, the subimago, which moults into a sexually mature adult, the imago. Mayflies "hatch" (emerge ...

Atopopus
''Atopopus'' is a genus of mayfly under the family Heptageniidae. Species of this genera usually have brown staining near the edges of their forewings and hindwings Insect wings are adult outgrowths of the insect exoskeleton that enable insects to fly. They are found on the second and third thoracic segments (the mesothorax and metathorax), and the two pairs are often referred to as the forewings and hindwi ....

Rhithrogena Germanica
''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''. It emerges as a subimago at the end of winter, and can be distinguished from similar species by a dark spot on the femur of each arthropod leg, leg. Description Adults and subimagos of ''Rhithrogena'' species have two long tails, and readily visible hind wings. ''R. germanica'' can only be distinguished from related species such as ''Rhithrogena semicolorata, R. semicolorata'' (the only other ''Rhithrogena'' species in the United Kingdom) by the presence of a dark spot on the femora of the arthropod leg, legs. A similar species, ''Ecdyonurus venosus'' (the ''late March brown'' or ''false March brown'') is more widespread in Great Britain, but emerges later in the year than ''R. ...
