NO COMMON NAME (Chiloporter eatoni): SPECIES ACCOUNTS
BROWN MAYFLY (Ephemera vulgata): SPECIES ACCOUNTS

Mayflies are found on all continents except Antarctica and a few small islands in the middle of the ocean. They are most abundant in mild or tropical climates.

The World Conservation Union (ICUN) lists two species of mayflies as Extinct, meaning that no members of the species are still alive, and one as Vulnerable, meaning that it faces a high risk of extinction in the wild. The main reasons for declining populations of mayflies are habitat destruction by pollution; deforestation, or the clearing of land of trees, at the margins of rivers; dam construction; and introduction of foreign fish.

Mayflies: Ephemeroptera - Physical Characteristics

Mayflies range in length from 0.04 to 3.2 inches (1 to 81.2 millimeters). They come in a variety of colors, including white, yellow, pinkish, gray, or black. The adults always have wings. In fact, this is the oldest group of winged insects alive today. One mayfly fossil (FAH-suhl), an impression of a mayfly left in mud in ancient times and hardened into stone, has a wingspan of 18 inches (45.7 cen…

Mayflies: Ephemeroptera - Behavior And Reproduction

Mayfly larvae are important in transferring energy in freshwater habitats. The larvae strain and eat large amounts of algae as food. They transfer the algae's energy to other animals when fishes, birds, insects, and spiders eat them. Most larvae remain hidden during the day to avoid predators (PREH-duh-ters), or animals who hunt them for food, but others are found swimming out in the open i…

Mayflies: Ephemeroptera - Brown Mayfly (ephemera Vulgata): Species Accounts

Physical characteristics: Adults are 0.55 to 0.86 inches (14 to 21.8 millimeters). Their wings are spotted. The larvae have mouthparts that look like miniature elephant tusks. They use these tusklike jaws for burrowing in the mud. The large abdominal gills are fringed and used, in part, to create a water current inside the burrow, as a way to maintain a steady flow of oxygen-rich water and food pa…
