Bekyně černé L (Arctornis l-nigrum) je druh nočního motýla z čeledi bekyňovitých, vyskytující se také na území České republiky.[1]
Popis
Rozpětí křídel se pohybuje mezi 35–45 mm.[2] Základní barvou je sněhově bílá. Velmi se podobá bekyni vrbové, od které se ale liší modrozeleným nádechem předních křídel a skvrnou ve tvaru tenkého černého písmene „L“ zhruba uprostřed při jejich předním okraji.[3]
Rozšíření
Vyskytuje se na území téměř celé Evropy (s výjimkou nejjižnějších a nejsevernějších oblastí) a zasahuje až do východní Asie. Na Britských ostrovech se vyskytuje jen vzácně, naposledy byla zaznamenána v Essexu mezi lety 1947–1960.[1][4][5]
V krajině vyhledává výslunné svahy pokryté listnatými lesy a křovinami.[2] Na místech výskytu se objevuje jen jednotlivě a nehojně,[5] což může být důvodem, proč některé prameny hodnotí tento druh jako vzácný.[2][3]
Bionomie
Během roku vytváří jednu generaci, jejíž motýli létají během červnových a červencových nocí,[2] někdy ještě v srpnu. V jižních oblastech výskytu se lze setkat i s neúplnou druhou generací (konec srpna až říjen).[5] Podobně jako u jiných druhy bekyní, i u bekyně černé L se housenky líhnou z vajíček na podzim a po krátkém období žíru přezimují, aby na jaře pokračovaly ve vývinu. Nejsou příliš specializované; mohou se živit například listím buku, břízy,[4] dubu, lípy,[5] jilmu, lísky a dalších dřevin.[2] Mladé housenky při vyrušení na listech unikají potenciálním predátorům pádem do podrostu.[5]

France Trip - Las Descargues - 27/06/16 to 01/07/16 - Part One - Macro's Hello all. I recently got back from a really enjoyable 5 nights of Moth trapping, Butterfly and Bird watching in the Midi-Pyrenees. I went with good friends Roger and Steve whom accompany me on many trips out in our County or Hertfordshire. It was decided at the end of last year that we should go for a short week away to sample some of the Moths that would be on offer in South-Wast France.
The article below is copied from Robin Howard's Lot Moths website. He describes it perfectly so didn't feel the need to re-write it!
"The Gite that we stayed in lies in a stunningly beautiful part of the Haute Quercy in the Lot southwest France. Located at the end of a ridge overlooking the Bave Valley it is surrounded by rolling, wooded hills, deep, river-cut gorges and on the nearby Causse, limestone pavement. The proximity of the limestone Causse de Gramat and volcanic Massif Central have produced a complex local geology that has formed the basis for a mosaic of habitats supporting a diverse flora with a rich moth and butterfly fauna. Over 1820 species have been recorded so far from the immediate area with more than 1600 species taken from the environs of the farm alone. Mercury vapour and actinic traps are run throughout the year in and around the farm with weekly forays made onto the limestone pavement and local poplar plantations, whilst the nearby volcanic peaks are regularly visited during the summer months for the more esoteric species. For further information regarding holidays and research opportunities at our farm and for a full description of the area and available accommodation please visit our sister site at www.lasdescargues.com or email us for a comprehensive information pack".
Robin and Sue are both fantastic hosts and could not do enough for you, I urge anyone to go there and experience the amazing wildlife that is on offer there.
The species site list is in excess of an incredible 2000 species of Moth! In 16 years that is incredible, and shows how special this habitat really is.
Our target was 300 species and with over 200 Macro's we may just get to the 300 mark with the Micro's still to sort.
We ran 2 static traps in the garden (Both MV 125s) and I brought my 160w MBT Blended bulb on a tripod. We then had access to a further two traps, an MV Robinson and an Actinic Midi-Robinson which we could take further afield, in fact we tried three further sites.
Macro Moths listed so far... Species in red are completely new to me The Micro's are still pending and a lot are so far unnamed!
