Hexagenia limbata. (Serville, 1829) [1] Hexagenia limbata, the giant mayfly, is a species of mayfly in the family Ephemeridae. It is native to North America where it is distributed widely near lakes and slow-moving rivers. [2] The larvae, known as nymphs, are aquatic and burrow in mud and the adult insects have brief lives.
Hexagenia are commonly referred to as burrower mayflies as they create u-shaped tunnels in the aquatic substrate where they reside. This shape allows them to draw in water from the surrounding areas by undulating their body near the mouth of the tunnel. Hexagenia feed upon microscopic organisms suspended in the water column and thus draw in all ...
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.
Ephemera danica can reach an imago size of 15–20 mm (0.6–0.8 in) in males, while females are larger, reaching 16–25 mm (0.6–1.0 in). This mayfly, with its characteristic markings and three tails ( Cerci ), is the most commonly seen of British Ephemeridae. Imago wings are translucent with dark veining, while in subimago they are dull and ...
The Heptageniidae (synonym: Ecdyonuridae) are a family of 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. [1] The group is sometimes referred to as flat-headed mayflies or stream mayflies.
This list of the mayflies recorded in the British Isles follows Macadam, [1] with nomenclature and taxonomy according to Kluge. [2] There are 51 species of mayfly known to occur in the British Isles, distributed among ten families. Ameletidae. Ameletus inopinatus Eaton, 1887; Arthropleidae. Arthroplea congener Bengtsson, 1908; Baetidae
Tomah mayfly nymphs and sub-adults feed predaceously on other invertebrates in the floodplains, which is unusual as other species of mayflies feed on dead plant material. [4] Siphlonisca is a monotypic genus, meaning Siphlonisca aerodromia is the only species within this genus. [7] The species is univoltine, meaning one generation is produced ...
