Burrowing Mayflies. A thread Part 1: Ephemeridae, Polymitarcyidae, and (Potamanthidae) are three families of mayflies whose ecology is strongly shaped by associations with fine-sediment habitats in rivers and streams and their burrowing habits #Ephemeroptera 1/6
Dorsal view of larvae of Anthopotamus (Ephemeroptera:Potamanthidae)
Close up of head, Anthopotamus (Ephemeroptera:Potamanthidae)
Third taxa - Anthopotamus (Ephemeroptera:Potomanthidae), the "Hackle-Gills". Forked gills projecting laterally, tusks projecting beyond head. Less of a burrower. Still have cool tusks 😊 #Ephemeroptera 6/6
Head of Polymitarcyidae (Ephemeroptera). Long downward curving tusks with tubercles on upper surface
lateral view of Polymitarcyidae larvae. Long forked gills on abdominal segments 2-7.
A second family of burrowing mayflies, Ephoron spp. (Ephemeroptera:Polymitarcyidae). Downward facing tusks with tubercles on upper surface and large forked gills. Also known for having large mass emergences. #Ephemeroptera 5/6
We have a third genera of Ephemeridae, Litobranchia retrocurva (Ephemeroptera:Ephemeridae). 1st gill is small and unbranched. #Ephemeroptera 4/6
Dorsal view of head, domed frontal process, prminent whorled flagella/setae? on antennae
Detail of gills of Hexagenia
second genera of Ephemeridae! Hexagenia spp (Ephemeroptera:Ephemeridae). Note the rounded/conical frontal processand whorled setae on antennae. Gorgeous gills! Hexagenia is known for large mass emergences, #Ephemeroptera 3/6
Burrowing mayfly of Ephemeroptera:Ephemeridae: Ephemera spp. Dorsal view of head. Note the forked frontal process
Burrowing mayfly of Ephemeroptera:Ephemeridae: Ephemera spp. Lateral view of head with upturned tusks
Burrowing mayfly of Ephemeroptera:Ephemeridae: Ephemera spp. Fluffy abdominal gills on dorsal area of abdomen
Below are images of Ephemera (Ephemeroptera:Ephemeridae), who often contruct U-shaped burrows in depositional substrates. Note the forked frontal process.. #Ephemeroptera 2/6
3/4 We assessed if #eDNA can capture the temporal changes of #Ephemeroptera, #Plecoptera, #Trichoptera, and #Diptera.
We found pronounced, cyclic phenological trends in most groups: the communities diverged from spring to summer and then in fall gradually returned closer to the spring state.
Ein paar #Ephemeroptera hab ich zum #HexapoDezember, aber nicht viele...
Nur bei der zweiten bin ich recht sicher: Ephemera danica (Große Eintagsfliege)
Ich habe Ende Mai 2023 am Pfäffiker See welche erspäht und gut 💯 unscharfe Bilder produziert 😄#HexapoDezember #Ephemeroptera
Happy 16. #HexapoDezember. Wenn Du nur 1 - 4 Tage, im Extremfall nur 40 Minuten lebst, Dich aber im Fluge vermehrst dann bist Du vermutlich eine archaische, wunderhübsche und komplett beeindruckende Eintagsfliege🥰 (englisch Mayfly) #Ephemeroptera (griechisch ephemeros ✨ „eintägig“, pteron „Flügel“)
🎄 Day 8 brings us some Mayfly Magic 🪰
#Ephemeroptera are primitive winged insects that are sensitive to pollution, making them key water quality indicators.
#FunFact: Adult lives can last anywhere from a few hours to just days.

Sweet lil Mayfly (Callibaetis[?]) chilling on a wall, sporting some really nice stone-like coloration.

These have been EVERYWHERE the past few days. I hear its a sign of good water quality though so that's nice #Ephemeroptera #bugsky

Lateral view of an exuvia of a mayfly
Exuvia of a mayfly seen from above. You can see the rift from which the mature individual emerged.
More detailed view of the mayfly's exuvia
The individual emerged from the moult, with diaphanous wings typically held upright, two large "turban" eyes, long front legs, long cerci (tail-like appendages).
I found a mayfly that had just emerged from its exuvia after moulting!
Photos 1-3: exuvia.
Photo 4: newly moulted individual. Diaphanous wings typically held upright, large "turban" eyes, long cerci (tail-like appendages).
Fascinating!

Litobranch recurvata (Ephemeroptera: Ephemeridae) larvae
Mandibular tusks
Antennae lack the big whorl like setae like in Hexagenia
1st abdominal gill is small, a single filament
A cool burrowing mayfly (Ephemeroptera: Ephemeridae) from eastern North America - from last year's class samples from a stream in central Pennsylvania. Litobrancha recurvata (McCafferty, 1971). #macroinvertebrates #Ephemeroptera

Mayfly gills are amazingly diverse. Often the fragile gills of Family Leptophlebiidae fall off in preserved specimens, but sometimes their relatively intact #mayflymonday #Ephemeroptera #macroinvertebrates
The next issue of the #Mayfly Newsletter (dc.swosu.edu/mayfly/) should be out in mid-December. If you have any notices, photos, articles or stories relating to mayflies and mayfly research that you would like included, please send them to the editor at giberson(at)upei.ca by Dec. 10. #Ephemeroptera

Do you even flex, bro?

Prepping a presentation for a teaching gig and I'm one image short of what I need; can anyone help with an image of Cloeon dipterum (Ephemeroptera) please? #mayflies #imagery #ephemeroptera Image of Coenosia ruficornis www.dipteraid.co.uk
Baetis rhodani
A run out for the Trent Biotic Index recording water quality in a local watercourse this morning.
The bulletproof (sewage-proof) Mayfly larva, Baetis rhodani.

Don't have a clue on the many different #ephemeroptera spp in their adult stage. Still would like to know what beauty landed here on the fig tree in our garden (NÖ). #Mayfly experts...
