Die Rötliche Herbsteule (Agrochola helvola) oder Weiden-Herbsteule ist ein Schmetterling (Nachtfalter) aus der Familie der Eulenfalter (Noctuidae).
Die Flügelspannweite der Falter beträgt 34 bis 45 Millimeter.[1] Das Farbspektrum der Vorderflügel ist sehr groß und weist rötlichbraune, grüngraue, ockergelbe oder rote Tönungen auf.[2] Die Nierenmakel heben sich kaum von der Grundfärbung ab und sind unten grau oder braun gefüllt, Ringmakel sind undeutlich, Zapfenmakel nicht zu erkennen. Besonders markant ist das bandförmige, leicht verdunkelte Feld zwischen Wellenlinie und äußerer Querlinie. Zusätzlich heben sich an der Wellenlinie dunkle Punkte ab. Die graubraunen Hinterflügel schimmern am Rand hell rötlichgelb.
Das Ei ist zunächst rötlichgelb und verfärbt sich vor dem Schlüpfen in einen rötlichhellbraunen Farbton und zeigt weiße Flecke und einen gelblichen Eiboden. Die Raupen sind gelbbraun oder rotbraun gefärbt, besitzen dünne, weiße Rücken- und Nebenrückenlinien, breite, weiße, scharf begrenzte Seitenstreifen sowie weißliche Punktwarzen. Die Puppe hat zwei feine Borsten am Kremaster.[3]
Das Vorkommen der Art erstreckt sich über nahezu ganz Europa, nördlich bis Schottland und Fennoskandinavien bis jenseits des Polarkreises, südlich bis Spanien, Sizilien (sie fehlt jedoch auf Sardinien), Griechenland sowie weiter über Vorder- und Mittelasien bis zur Mitte Sibiriens.[4] Im Gebirge kommt sie bis auf über 1400 Meter Höhe vor.[3] Die Rötliche Herbsteule ist in den verschiedensten sowohl trockenen als auch feuchten Lebensräumen wie Buschwäldern, Berg- und Wiesentälern, Heidelbeerheiden oder Parklandschaften sowie in Ufergebieten und Feuchtwiesen anzutreffen.
Die Falter zählen zu den nachtaktiven Tieren. Sie sind meist spärlich an künstlichen Lichtquellen zu finden, erscheinen aber regelmäßig und teilweise in großer Anzahl an Ködern.[5][6] Hauptflugzeit sind die Monate September und Oktober. Die Raupen leben überwiegend im Mai und Juni. Sie ernähren sich von den Blättern einer Vielzahl von Pflanzen, beispielsweise von[4]
und anderen. Vor der Verpuppung in einer festen Erdhöhle liegen sie wochenlang als Praepupa im Kokon.[4] Die Art überwintert als Ei.
Die Rötliche Herbsteule ist in Deutschland weit verbreitet und gebietsweise zahlreich anzutreffen, so dass sie auf der Roten Liste gefährdeter Arten als nicht gefährdet eingestuft wird.[7]

Agrochola helvola, the flounced chestnut, is a moth of the family Noctuidae. It was first described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae. The species is found in most of Europe, north to Scotland and Fennoscandia up to the Arctic Circle, south to Spain, Sicily (it is not found on Sardinia), Greece further east to the Middle East, Armenia, Asia Minor, western Turkestan and central Asia up to central Siberia.
The wingspan is 34–45 mm. The colour of its forewing is either dull or bright red with inner, outer, and submarginal lines brownish, formed of lunules between the veins, those of the inner line more continuous; a distinct brownish angulated median shade. Its stigmata is usually very indistinct, of the ground colour or slightly darker, with paler annuli. Its hindwing is grey, with costal and terminal areas and the fringe generally ochreous or rufous. The basal area before inner line and the space between outer and submarginal lines are darker, forming more or less prominent bands.
The dull reddish examples with these bands well-developed are typical helvola; the bright red ones are rufina L.; — catenata Esp. is a moth in which the space between the outer and submarginal lines is not filled up with darker colours, so that the dark lunules forming those lines are more conspicuous; the examples with a greenish grey or ochreous ground colour, with the bands also developed are ab. ochrea Tutt ; — those with a yellowish ground and purplish-brown bands are punica Bkh. The lines and bands are often obscured and semiobsolete. These less-marked forms with dull reddish ground colour are unicolor ; — with bright reddish ground colour called rufa Tutt; — and with greenish ochreous ground colour called extincta Spul.; sibirica Stgr. from Central Asia, has pale yellow forewings; cinnamomea Fuchs has much grey suffusion, the area beyond outer line has darker brown; specimens from Amasia, though reddish in a few cases, mostly females, are generally much paler than European, dull brownish or ochreous-grey, with indistinct or obsolete markings; in particular the hindwings are much whiter with the grey and rufous suffusion usually slighter and more restricted in area.[1] The egg is initially reddish yellow becoming, before hatching, a reddish-light-brown hue showing white spots and a yellowish egg base. The caterpillars are coloured yellow-brown or red-brown, have thin, white dorsal and dorsolateral lines and wide, white, sharply limited lateral stripes as well as whitish point warts. The pupa has two fine bristles on the cremaster.
Agrochola helvola has a wide habitat range from xerothermic grasslands over mesophilic edges to fens, stream margins and other unimproved habitats. The moth flies from September to October depending on the location.
The larvae feed on the leaves of various plants. Recorded food plants include Salix, Quercus, Corylus, Prunus spinosa, Rubus fruticosus, Rubus idaeus and Vaccinium myrtillus.

De roodachtige herfstuil (Agrochola helvola) is een nachtvlinder uit de familie van de uilen, de Noctuidae.
De voorvleugellengte bedraagt tussen de 16 en 18 millimeter. De grondkleur van de voorvleugels is bruin, soms met groenige of rodige tint. De vleugel is breed met een vrij spitse apex. Dwars over de vleugel lopen roodachtige banden.
De roodachtige herfstuil gebruikt allerlei loofbomen als waardplanten, maar ook bosbes en struikhei. De rups is te vinden van april tot juni. De soort overwintert als ei.
De soort komt verspreid over het Palearctisch gebied voor.
De roodachtige herfstuil is in Nederland een niet zo gewone en in België een zeldzame soort. De vlinder kan verspreid over het hele gebied worden gezien, met name op zandgronden en in de duinen. De vlinder kent één generatie die vliegt van eind augustus tot halverwege november.

Rødt høstfly (Agrochola helvola) er en sommerfugl som tilhører familien nattfly (Noctuidae). Den er vanlig i Sør-Norge.
Et middelsstort (vingespenn 36 – 40 mm), kraftig, brunrødt nattfly, vanligvis lett å kjenne igjen på fargen og på forvingens form. Kroppen og forvingen er brunrøde. Forvingen er tydelig tilspisset, ikke avrundet ytterst som hos de fleste lignende arter. Tegningene er gjerne utydelige, men vanligvis kan man i alle fall ane to tverrstriper (mellomlinjer), en nær roten og en nær vingespissen. Området utenfor den ytterste tverrstripen er noe mørkere enn resten av vingen. Nyre- og ringmerkene er vanligvis utydelige. Bakvingen er grå, lysere og litt rødlig langs ytter- og framkantene.
Rødt høstfly finnes i skog, skogkanter, hager og parker. Larvene lever på ulike busker og trær om våren, i de nordligste delene av utbredelsesområdet mest på røsslyng (Calluna vulgaris), . Den overvintrer som egg. De voksne sommerfuglene flyr om natten fra slutten av august til begynnelsen av oktober, og kommer gjerne til lys.
Arten forekommer over det meste av Europa, i Midtøsten og i de vestlige og sentrale delene av Sibir. I Norge er den vanlig nord til Trøndelag, det finnes funn nord til Rana i Nordland.
