Something very interesting has been going on with Leucorrhina caudalis in The Netherlands. 20 Years ago this species was considered extinct in The Netherlands, with the last known populations disappearing around 1970. More or less the nearest known populations were in the North of France and Dutch people who wanted to see the species went there.
In 2006 a male was found near Maastricht in the province of Limburg. We thought this was incredible. It was seen by many observers. During an organized excursion it was also seen mating with a female, but in subsequent years it was not seen again. Until 2008 or 2009, when a male was photographed in Nature Reserver The Weerribben (Overijssel) by a group of Belgian dragonfly enthousiasts. Then in 2010 a emerging individual was found (again by a Belgian) during an excursion. And in 2011 it was found at several locations in The Weerribben. Since then, numbers have been growing enormously in The Weerribben. The same happened in The Wieden and nearby areas in Friesland.
In recent years the species seems to be spreading from these areas with single individuals popping up at a number of places and a population found a bit further away in Overijssel. This year, 2018, the species has suddenly appeared at many places, with individuals at over 20 new locations and in 9 of the 11 Dutch provinces. Some individuals appear to be single wanderers, but in some places up to 12 males have been seen. Some may refer to small new populations or are in areas that hold clear potential for populations. Exciting times and we are very curious what these developments lead to (Johan van ‘t Bosch).
NatureToday: De geelvlekheidelibel lijkt uit Nederland verdwenen. Niet lang geleden vloog deze soort met grote gele vlekken in zijn vleugels, nog regelmatig tussen de andere kleine rode heidelibellen. De laatste jaren is zijn trend sterk gedaald en uit 2017 is er geen enkele zekere waarneming bekend. Waarschijnlijk is veranderend habitat in Oost-Europa door drogere zomers en toegenomen bemesting de oorzaak. 
De NVL Landelijke Studiedag 2018 was een onverdeeld succes, met wel acht interessante lezingen, zodat er niet eens tijd was voor de traditionele quiz (volgend jaar toch maar weer wel hopen we). Er waren rond de zeventig aanwezigen, waaronder ook enkele niet-leden. De nieuwe zaal werd door de aanwezigen als prettig ervaren en de meer centrale locatie was voor deelnemers uit de zuidelijke contreien een verademing qua reistijd. Na afloop kon nog even worden nagepraat aan de bar en is in een Italiaans restaurant in de buurt nog gezellig nagetafeld.
t has been known for some time that dragonfly wings possess antimicrobial properties, but attempts to gain a greater insight into the mechanism responsible for this have been hampered by the fragility of the wings, which can be easily damaged under the light of a powerful microscope. Now, researchers at the Queensland University of Technology (QUT) have used a new technique to produce intricate, detailed images that show how more than 10 billion tiny "fingers" lining the wing surface make bacteria tear themselves apart. 
NatureToday: Afgelopen zomer bleek uit tellingen in de Krimpenerwaard een zeer sterke achteruitgang van de groene glazenmaker: maar liefst 90 procent vergeleken met 2016. Deze zeldzame en beschermde libel is gebonden aan sloten met krabbenscheer. Om nog onbekende reden werd deze plant in 2017 vroeg bruin in de Krimpenerwaard. Dit jaar proberen we de oorzaken van deze zorgelijke resultaten te achterhalen.
