The Atlas of the Mosquitoes of Luxembourg has just been published in the Ferrantia series of the National Museum of Natural History and describes 28 species (31 taxa) of culicides found in the Grand Duchy.

Mosquito-borne diseases such as chikungunya, dengue, Usutu or West Nile, have come back to the forefront in both human and animal health. To prevent outbreaks, it is necessary to acquire a solid knowledge of the mosquito fauna in the considered area. Therefore, and since the mosquito fauna of Luxembourg was only partially known, we suggested the construction of the first comprehensive mosquito diversity and distribution database for the Grand Duchy as a base for an atlas. This atlas of the mosquitoes of Luxembourg assembles a taxonomic list and species’ distribution maps.

The Atlas was developed in the framework of the MosquitoLUX (2019-2022) project implemented under the auspices of the Fondation faune-flore at the Scientific Research Centre of the National Museum of Natural History in Luxembourg. The Fondation faune-flore was the host institution and administrative manager of the project.

Brief description

Spergularia marina, also called Spergularia salina, is a species of flowering plant in the family Caryophyllaceae. It is known as salt sandspurry or lesser sea-spurrey. S. marina is a sprawling annual or sometimes perennial with stems up to 35 cm long. Like other sea-spurrey species, its flowers have white to pink petals, with sepals usually longer than the petals, at 2.5–4 mm. Plants are salt-tolerant, being found by the sea and in saline areas inland as well as in areas along roadsides affected by de-icing salts (Wikipedia contributors 2022)..

Status and distribution in Luxembourg

Records of Spergularia marina (L.) Besser in Luxembourg. Data source: Recorder-Lux, iNaturalist & GBIF, 2023-02-09.

Spergularia marina (L.) Besser was first documented in Luxembourg in 2019, near Garnich (Krippel et al. 2020), Findel and Hoscheid (MNHNL 2000-). Selective investigations have shown that S. marina is well represented in Luxembourg. Even if the lesser sea-spurrey was not recorded by Ehl et al. (2019) during the survey of salt-tolerant vascular plant species along roads in Luxembourg – although known near Arlon in Belgium (Remacle 2015) –, this probably overlooked species must have been present in Luxembourg long before 2019. The sub-cosmopolite S. marina – usually found by the sea and in saline inland areas –, with a salinity index of 9 after Ellenberg (2001), is in expansion in the territory of the ‘Nouvelle Flore’ (Lambinon & Verloove 2015) and adjacent regions in Germany (Hand et al. 2016). In 2021 and 2022 many new locations were found in Luxembourg and Spergularia marina thus can be considered as naturalised in the Grand Duchy, mostly on surfaces affected by de-icing salts along roadsides, where it often grows together with Puccinellia distans, another halophyte. 32 observations of the species have been documented in the Recorder-Lux database between 2019 and 2022.

First detection of the invasive Asian tiger mosquito Aedes albopictus in Luxembourg

CDC-Gathany-Aedes-albopictus-2The Ministry of Health informs that a population of the invasive Asian tiger mosquito Aedes albopictus has been detected at two locations in the territory of the Commune of Roeser. This first appearance of the tiger mosquito in the Grand Duchy has been confirmed by an international expert in the field. According to current information, this is a limited phenomenon. The tiger mosquito does not move very far and usually does not travel more than a hundred metres from its birthplace.

In the next few days, the Luxembourg authorities, with the support of an expert, will assess the situation, as well as set up a prevention plan and a surveillance and eradication system. The use of insecticides is currently under consideration. However, eradication would be mainly through the elimination of potential habitats.

Alert system for iNaturalist neobiota observations in place in Luxembourg


Since 2021-07-14, an alert system concerning iNaturalist neobiota observations from Luxembourg has been operational. Paul Braun, digital curator at the Luxembourg National Museum of Natural History, has implemented a Python code executed every day at 12:00 CET (= 13:00 local time) which sends an email alert message to key persons in charge of neobiota early detection and surveillance in Luxembourg. Independently from their quality grade, all observations since the day before 00:00 CET until the current day 12:00 CET are compiled and sent to , and thereafter dispatched to a selection of key persons. We chose 12:00 CET to enable a rapid response in case of observations of important species occur on the current morning. Unfortunately, the iNaturalist API does not give the option to choose precise periods for data extraction, which results in an overlap of the periods covered by the alert messages.

If interested, other member states of the European Union are welcome to obtain the code in order to set up a similar alert system for their country. The contact email address is .

Recommendations to iNaturalist: it would be useful to implement the following in future versions of the API:

  • enable the selection of a specific set of fields needed for a query (currently only complete data sets can be selected, which causes transfer of high data volumes and has a negative impact on climate and environment);
  • enable precise periods for observation queries.

An alert system for neobiota observations recorded in the national database on natural heritage Recorder-Lux has been operational since 2019. It triggers an alarm message as soon as an observation is entered in data.mnhn.lu or uploaded to the Recorder-Lux database. It was implemented by Armand Turpel.

Thus, most neobiota observations from Luxembourg will trigger an alarm in a timely manner. However, a small gap remains: the observations of invasive alien bird species via the database of the Centrale Ornithologique du Luxembourg (COL) do not yet trigger an alarm in a timely manner. This currently concerns the following 4 bird species: Mandarin duck (Aix galericulata), Egyptian goose (Alopochen aegyptiaca), Canada goose (Branta canadensis) and Rose-ringed parakeet (Psittacula krameri).

First sighting of Vespa velutina nigrithorax in 2021

On Sunday 13 June 2021, a citizen of Rumelange discovered an initial nest of an Asian black hornet (Vespa velutina nigrithorax) and reported it to the Natural History Museum. The initial nests of the native Eurasian hornet (Vespa crabro) look very similar.

Note: This occurrence/detection of an Invasive Alien Species of Union concern named Vespa velutina nigrithorax has been notified on 16 June 2021 by Luxembourg, pursuant to Article 16(2) of R.1143/2014. The EASIN Notification System automatically warns (all the other) European Member States whenever the occurrence/detection of an IAS of Union concern is notified.

Brief description

Phytolacca americana sl25

Mature Pokeweed in a xerothermic wood in Lower Austria

Phytolacca americana L. is widely naturalised in ruderal sites and in nature-like habitats in southern Europe, extending northwards to central France. Semi-natural habitats colonised include heaths, open woodlands, clearcut areas and forest edges. In Belgium, it is commonly used as an ornamental; it is planted in gardens and public green areas but doesn’t reproduce in the wild so far. Under suitable environmental conditions, the American pokeweed forms dense populations that can outcompete native vegetation and prevent regeneration of forest species. The plant produces toxic saponins (Branquart et al. 2010).

IAS of Union concern

In 2020, Phytolacca americana L. was proposed as a candidate species to join the list of invasive alien species of Union concern.

Status and distribution in Luxembourg

Records of Phytolacca americana L. in Luxembourg. Data source: Recorder-Lux, iNaturalist & GBIF, 2023-02-09.

The oldest herbarium specimen at the Museum dates back to the 19th century: it is a specimen from Siebenbürgen from the A. Georges herbarium in Gotha found in the Koltz herbarium, probably an exchange specimen (Specimen № 15712, MNHNL 2000-).

The oldest reference to Phytolacca in Luxembourg is found in the Bulletin of the Luxembourg Naturalist Society, when Eugène Beck circulates a sample of Phytolacca […], known from some of Luxembourg City’s ornamental gardens (Anonyme 1946). We assume it to be Phytolacca americana L., as Phytolacca acinosa Roxb. has not yet been observed in Luxembourg. It was first recorded in Belgium in 1960 (Verloove 2021).

The first documentation of the American pokeweed in the wild was recorded in 1980 by Pierre Becker in a fir plantation downstream of Soup in the municipality of Heffingen (Reichling 1985: 136; Obs. key: DSS00465000000CI in MNHNL 2000-).

Grown for ornamental purposes in gardens. Very rare subspontaneous or adventitious; naturalised towards the SW limit of the Flora’s territory: roadsides, waste ground, … The fruits of this species are poisonous, unlike those of Phytolacca acinosa Roxb., which is also grown in gardens for ornamental purposes, but especially for its fruits used as a colouring agent (Lambinon & Verloove 2012: 122).

Brief description

Hyalomma marginatumHyalomma marginatum C. L. Koch, 1844 is a species of tick within the Ixodidae family, with a distribution in subtropical regions of the Old World. The sexual animals (imagines) suck blood from a variety of mammalian species, preferably hoofed animals, but occasionally also from humans. Immature forms occur on a variety of vertebrates, including migratory birds. The species has medical importance as a vector of Crimean-Congo hemorrhagic fever (CCHF) and typhus (Wikipedia Bearbeiter, 2020).

This tick has been implicated in the transmission of Bahig virus, a pathogenic arbovirus previously thought to be transmitted only by mosquitoes (Wikipedia contributors 2020).

Status and distribution in Luxembourg

Records of Hyalomma marginatum C. L. Koch, 1844 in Luxembourg. Data source: Recorder-Lux, iNaturalist & GBIF, 2023-02-09.

A male Hyalomma marginatum sensu stricto C. L. Koch, 1844 was collected on 2018-08-31 in the city of Dudelange, representing the first record of this species in the country. Subsequent to this finding and its media attention, two further Hyalomma sp. sightings were reported. On 2020-06-14, a male H. marginatum sensu stricto was collected in Beaufort while infesting a horse. After release, the tick very quickly tried to escape and turned towards another horse nearby. On 2020-07-06, a female Hyalomma sp. was found crawling on a horse in Aspelt, which was outside for a maximum of five minutes (Fig. 2b). Both latter ticks were collected from the uppermost interior site of the rear legs of the horse, between the thigh and the belly. It was not possible to identify the female tick further since only images were available (Weigand et al. 2020).

Two observations have been reported in the Recorder-Lux database so far (MNHNL, iNaturalist & GBIF 2022).

Brief description

Dermacentor reticulatus M 070825Dermacentor reticulatus Fabricius, 1794 is a species of tick within the Ixodidae family. It is the type species for the genus Dermacentor. D. reticulatus is an ornate tick. The female varies in size from 3.8–4.2 mm (unfed) to 10 mm when engorged after feeding. The unfed male is 4.2–4.8 mm long. D. reticulatus is found in Europe and Western Asia, generally in wooded areas. D. reticulatus is a vector of various disease organisms, including Babesia canis, Francisella tularensis, Coxiella burnetti, Theileria equi, and several Rickettsia species, such as Rickettsia slovaca (Wikipedia contributors, 2020).

As a habitat, the marsh tick prefers humid areas such as riparian forests and moors as well as deciduous forests. Marsh ticks require a summer temperature of 20-22 °C and rainfall of 400-1000 mm. The ticks are cold-tolerant and can survive hard winters. Originally found in Hungary, Austria and northern Italy, the distribution area of the marsh tick has expanded strongly northwards since the 1970s. In Germany, the first natural population was described in 1973 on the Upper Rhine, and it was probably introduced by dogs. There are now free-ranging populations throughout Germany. Likely causes are an increase in natural biotopes, the associated increase in intermediate hosts, and global warming (Wikipedia Bearbeiter, 2020).

Status and distribution in Luxembourg

Records of Dermacentor reticulatus (Fabricius, 1794) in Luxembourg. Data source: Recorder-Lux, iNaturalist & GBIF, 2023-02-09.

Dermacentor reticulatus Fabricius, 1794 was first documented by Mark Klinker on 17 November 2015 in Wellenstein, municipality of Schengen (MNHNL, iNaturalist & GBIF 2020).

Between 2015 and 2020, six Dermacentor ticks were collected in the south of Luxembourg. Previously, these individuals had been identified as Dermacentor marginatus Leach, 1815. However, morphological re-investigation as well as DNA barcoding identified the specimens as Dermacentor reticulatus Fabricius, 1794. Thus only D. reticulatus is known from Luxembourg (Weigand et al. 2020).

52 observations have been reported in the Recorder-Lux database so far (MNHNL, iNaturalist & GBIF 2022).

The public debate on ticks in Luxembourg

Ticks are a topic of discussion in Luxembourg, both by the authorities (e.g. Direction de la Santé 2016) and by the press (e.g. Weisbrodt 2021). Ticks are regularly the subject of parliamentary questions, e.g. the question on the tick Dermacentor reticulatus submitted by member of parliament Cécile Hemmen in April 2021.
