Checked out Chasan Chua (McIntyre Creek) on my way to skiing today... but no stoneflies yet. Next week for sure! #Plecoptera #Whitehorse #Yukon
A long, dark insect on a wet rock. It is black with long feelers.
Another view of the stonefly.
Spotted what I think are Black Stoneflies (Austroperla cyrene) at the Rob Roy Glacier Track, Wanaka, New Zealand on 1 Jan 2026. They were moving on rocks near a stream.

Happy Bug-off Day!! Today we have two interesting orders: Neuroptera (lacewings) vs Plecoptera (stoneflies)🦗
Vote in the comments of this post until Monday for your favorite bug!!🏆✨

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.
🎄 #InsectAdvent Day 10 is #Plecoptera day!
#FunFact: Stoneflies are a sign of pristine rivers with healthy ecosystems. Their aquatic nymphs live under stones in fast-flowing highly-oxygenated streams and can take months or even years to mature.

Ein erwachsenes Exemplar der Steinfliege Perla marginata sitzt auf einem mit grünen Algen überzogenen Metallgeländer. Das Insekt zeigt die charakteristischen langen Fühler, die durchsichtigen, netzartig geäderten Flügel und den länglichen, bräunlich gefärbten Körper. Die gelben Markierungen am Hinterleib sind deutlich sichtbar, ebenso wie die kräftigen Beine mit ihren feinen Härchen. Das natürliche Licht hebt die Details der Flügelstruktur und die Textur des mit Algen bewachsenen Utergrunds hervor.
Detailaufnahme einer Steinfliege (Perla marginata) von oben, die die anatomischen Strukturen des Kopf- und Thoraxbereichs eindrucksvoll zeigt. Besonders auffällig sind die großen, dunkel gefärbten Facettenaugen, der kräftige Prothorax mit seiner charakteristischen Oberflächenstruktur sowie die am Körper anliegenden, durchsichtigen Flügel mit ihrer feinen Netzaderung. Die segmentierte Fühlerstruktur und die robusten Beine sind deutlich erkennbar. Das Insekt ruht auf einem mit Algen und Moosen bewachsenen Metallgeländer, was den typischen feuchten Lebensraum dieser als Gewässergüteindikatoren wichtigen Steinfliegenart widerspiegelt.
Eine Steinfliege (Perla marginata) in Aufsicht auf einem mit Algen bewachsenen Metallgeländer. Das Insekt zeigt deutlich die typischen Merkmale der Art: den robusten, dunkel gefärbten Körper mit metallisch glänzenden Partien, die großen, durchsichtigen Flügel mit ihrer charakteristischen Netzaderung, sowie die langen, dünnen Fühler und kräftigen Beine. Die Art dient in ihrem aquatischen Lebensraum als Bioindikatoren für saubere Gewässer.
Die räuberischen Larven (> 3 cm) der Steinfliege Perla marginata entwickeln sich in Fließgewässern guter Wasserqualität über 3 Jahre. Nach dem Schlupf fressen sie nicht mehr und sterben nach ca. 2 Wochen.

Close-up image of a small, light-brown insect viewed from the front, showing its head, thorax, and upper legs. The insect has two dark eyes and segmented antennae extending upward. The thorax features a symmetrical, dark brown pattern resembling an ornate or shield-like marking. The legs are outstretched laterally, and the background is pure white.

Dinocras cephalotes, is there anything more impressive under a stone in an English river. #Stonefly #Plecoptera This one from the River Bradford, Derbyshire earlier today.

For Microscope Monday 🔬 we present some magnificent magnification of the stunning #stonefly.
#Plecoptera are a very important component of British and Irish #freshwaters, most common in fast-flowing, clean rivers & streams.
Keen to improve your knowledge of #riverflies?

It's stonefly season once again along the Yukon River... watch this little Columbian Snowfly hike up over, under, and through the shore ice on its way to find a mate! #Plecoptera Utacapnia columbiana

The Riverfly HQ team headed out for their monthly sample today at Wilfin Beck in Near Sawrey. 💦
It was great to see some huge Stoneflies again happy in the high flowing water. Hardly fit on the spoon! 🙊

An interesting record from the #GSB2024, Genus Anacroneuria, 1st record in the Brazilian state of Santa Catarina, 3rd for the southern region of #Brazil, 31st for Brazil in #inaturalist 📸 @liuidarraga.bsky.social #Plecoptera
A large dark gray insect with intricately veined, dark gray wings. It has long black antennae, big black eyes, and dark legs and is resting on a floor of pale gray stone or concrete or something.
Was just reminded that in 2019 I found this dead stonefly on the floor of the lobby of my then office building

Any Stonefly experts out there please? Finishing up @DipteristsForum spring field trip to Radnorshire. A few 'by-catch' individuals to do. From upland mire next to a small fast-ish river. Is this Amphinemura sulcicollis please? #stoneflies #plecoptera
