The European Commission has published an update of the list of invasive alien species of Union concern in the Official Journal on July 13th 2017:
The webpage http://ec.europa.eu/environment/nature/invasivealien/ has been updated accordingly and includes a new brochure on all 49 species (at the moment only available in English pdf format): http://ec.europa.eu/environment/nature/pdf/IAS_brochure_species.pdf
The JRC report on the baseline distribution of the 37 species on the first list is available here: https://easin.jrc.ec.europa.eu/Docum entation/Baseline

In 2016, the Luxembourg National Natural History Museum has started a survey on mosquito species in Luxembourg. Between July and October mosquitoes have been weekly trapped on 10 sites throughout the country, in co-operation with local and regional partner organizations and private persons.
On June 14th and 15th 2017, Mosquito specialist Dr Francis Schaffner from University of Zurich determined the 2016 catches at the Museum.

182 mosquitoes were caught during 90 catches from 10 sites.
|Culex pipiens / torrentium (9 out of 10 sites)
|Anopheles plumbeus (Kockelscheuer, Steinsel)
|Culiseta annulata (Remerschen)
|Coquillettidia richiardii (Remerschen)
|Aedes vexans (Kockelscheuer)
|Aedes cinereus (Kockelscheuer)

Impatiens balfourii. Luxembourg, Kirchberg. Photo: Roland Proess, 5 August 2016.
Impatiens balfourii Hook.f. was first observed in Luxembourg, in the wild, in 2016, on the edge of the Kirchberg plateau by Roland Proess. It is at present just considered to be subspontaneous, it may however have the potential of getting naturalized in Luxembourg due to climate change.
Yves Krippel & Roland Proess have written a detailed article on the subject which was submitted to the next edition of the Bulletin of the Luxembourg Naturalist Society:
- Krippel, Y. & R. Proess, [submitted]. Impatiens balfourii Hook. f. (Balsaminaceae), nouvelle espèce subspontanée au Luxembourg ?! Bull. Soc. Nat. luxemb. 119.
Impatiens balfourii has been assessed today according to the ISEIA protocol by Yves Krippel and Christian Ries: B1, Watch list.
Two other invasive alien balsam species occur in Luxembourg: the Himalayan balsam (Impatiens glandulifera Royle), one of the most common and widespread invasive neophytes in Luxembourg, and the small balsam (Impatiens parviflora DC.), which is widespread in forest ecosystems across Luxembourg.
The distribution maps on neobiota.lu are from now on up to date. Every time a page concerning a species present in Luxembourg is viewed, the distribution data are retrieved on the fly by a query sent to the recorder database of the Luxembourg National Museum of Natural History.
These data are saved on the nebiota.lu server in GPX format and displayed using the OSM (Open Street Map) WordPress plugin.
