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.

Mayflies
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 (biology), 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 family (biology), families. Mayflies have ancestral traits that were probably present in the first flying insects, such as long tails and Insect wing, wings that do not fold flat over the insect morphology#Abdomen, abdomen. Their immature stages are aquatic fresh water forms (called "naiads" or "nymph (biology), 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 sub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
