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, 2025-05-13.

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.

Risk assessment

No risk assessments have been done to date.

Vespa velutina nigrithorax – Press release of 28/09/2020

Posted onAuthorDr. Christian Ries

Asian hornet (Vespa velutina)Since the beginning of September 2020, the first sightings of the Yellow-legged Asian Hornet (Vespa velutina nigrithorax) have been reported in Luxembourg. To date, its presence has been noted in Junglinster, Ingeldorf, Esch-sur-Alzette, Schifflange and Beckerich. Originally from South-East Asia, this hornet was introduced to France around 2004, and has since gradually colonised much of Europe, from Portugal to northern Germany.

The risk of stinging remains negligible as long as one does not approach its nest. The Yellow-legged Asian Hornet resembles the European Hornet (Vespa crabro), which is indigenous to Europe.

For more information about the Yellow-legged Asian Hornet and especially the characteristics allowing its identification, do not hesitate to consult the links below.

Invasive alien freshwater jellyfish Craspedacusta sowerbii spotted in Upper Sûre Lake

Posted onAuthorDr. Christian Ries

At the beginning of September 2020, freshwater jellyfish were spotted in the Upper Sûre Lake. Photographs of this jellyfish were sent by divers from the CGDIS Frogmen Group to the Water Management Administration (AGE) and the Nature and Forestry Administration (ANF). This observation made it possible to confirm the presence of the Craspedacusta sowerbii jellyfish in the Upper Sûre Lake.

Craspedacusta sowerbyi by OpenCageIt is true that the term “jellyfish” is reminiscent of marine species with a stinging nature, which can trigger painful skin reactions, similar to a burn, on direct contact with the animal. The freshwater jellyfish, on the other hand, is a harmless relative. Although it belongs to the group of cnidarians, it is completely harmless to humans.

Originally from Asia, the freshwater jellyfish has spread to other parts of the world mainly due to the introduction of aquatic plants and fish. This invasive alien species is no larger than 25 mm in diameter and prefers calm, stagnant waters that warm up considerably in summer.

As this jellyfish requires temperatures often above 20°C over a long period of time, its appearance takes place from July to October with a peak observed from the end of August to the beginning of September.

It should also be noted that these jellyfish prefer clean water. In the evening, they often come to the surface of the water and can be observed there. They can also be admired when diving at greater depths during the day. These jellyfish have also been reported in other surrounding areas. It is very likely that their proliferation will continue as the climate warms.

The problem of the appearance of blue-green algae (cyanobacteria), which is a real concern in many respects for the Upper Sûre Lake, is a phenomenon totally independent of the appearance of the freshwater jellyfish observed and described in this press release.

If you spot any jellyfish, you can report them at the following address: .

Brief description

Trachemys scripta (Thunberg in Schoepff, 1792) is a species of common, medium-sized, semi-aquatic turtle. It has been listed as one of the “Top 100” World’s Worst Invaders. These turtles often fight with native species for food, habitat, and other resources. Eventually they bully many native species out of basking sites – areas where there is sunlight and warmth for the species. When basking it is common that pond sliders will do so on birds’ nests, thereby killing the eggs. They also prey on young birds. Turtles that were raised in captivity can develop diseases that are unfamiliar to native species, which can be harmful. Turtles raised in captivity are often released because they become too much to handle or grow bigger than expected. It’s not uncommon that pond sliders will also run away (Wikipedia contributors 2020).

IAS of Union concern

In 2016, Trachemys scripta (Thunberg in Schoepff, 1792) was added to the list of invasive alien species of Union concern (Anonymous 2016) which implies that member states shall take all necessary steps to prevent its unintentional introduction or spread.

Status and distribution in Luxembourg

Records of Trachemys scripta (Thunberg in Schoepff, 1792) in Luxembourg. Data source: Recorder-Lux, iNaturalist & GBIF, 2025-05-13.

Currently, 173 records in Luxembourg are accessible through the MNHNL-mdata portal, when combining the species (145) with its two subspecies, T. scripta scripta (11) and T. scripta elegans (17) present in Luxembourg (MNHNL, iNaturalist & GBIF 2020).

Invasive pond sliders have been observed climbing the platforms of waterbirds, especially great crested grebes (Podiceps cristatus), to sunbathe, thus preventing successful breeding (Konter 2020: 81).

More details are available on the pages dedicated to both subspecies (see their distribution maps below).

Starr 040217-0077 Pennisetum setaceum

Pennisetum setaceum on Kahoolawe Island (Hawai)

Pennisetum setaceum (Forssk.) Chiov., commonly known as crimson fountaingrass, is a C4 perennial bunch grass that is native to open, scrubby habitats in East Africa, tropical Africa, the Middle East and SW Asia. It has been introduced to many parts of the world as an ornamental plant, and has become an invasive species in some of them. It is drought-tolerant, grows fast, reaches 3 feet in height, and has many purple, plumose flower spikes. Fountaingrass has been introduced to the Canary Islands, Sicily, Sardinia, southern Spain, Australia, South Africa, Hawaii, the Western United States, California, southern Florida and New Caledonia. It thrives in warmer, drier areas and threatens many native species, with which it competes very effectively as an invasive species. It also tends to increase the risk of intense wildfires, to which it is well adapted, thus posing a further threat to certain native species (Wikipedia contributors 2019).

IAS of Union concern

In 2017, Pennisetum setaceum (Forssk.) Chiov. was added to the list of invasive alien species of Union concern (Anonymous 2017) which implies that member states shall take all necessary steps to prevent its unintentional introduction or spread.

Parliamentary question of 5th September 2019 regarding the European list of invasive alien species

Posted onAuthorDr. Christian Ries

On 5 September 2019, Mars Di Bartolomeo, Member of the Chamber of Deputies, addressed a parliamentary question to the Minister of the Environment regarding the European list of invasive alien species.

Question 1

Which species on this list have been recorded in Luxembourg?

Response from Carole Dieschbourg, Minister for the Environment, Climate and Sustainable Development:

Plants (5 species):

  1. Tree of heaven (Ailanthus altissima)
  2. Himalayan balsam (Impatiens glandulifera)
  3. Giant Hogweed (Heracleum mantegazzianum)
  4. Nuttall’s waterweed (Elodea nuttallii)
  5. Parrot’s feather (Myriophylum aquaticum)

Animals (9 species):

  1. Spiny-cheek crayfish (Orconectes limosus)
  2. Signal crayfish (Pacifastacus leniusculus)
  3. Topmouth gudgeon (Pseudorasbora parva)
  4. Egyptian goose (Alopochen aegyptiacus)
  5. Pumpkinseed (Lepomis gibbosus)
  6. Coypu (Myocastor coypus)
  7. Muskrat (Ondatra zibethicus)
  8. Raccoon (Procyon lotor)
  9. Red eared slider (Trachemys scripta).

Question 2

Given that these species pose a threat to biodiversity and ecosystem services, what is his Ministry’s strategy for more effective eradication, management and control methods to combat the adverse effects associated with this phenomenon?

Response from Carole Dieschbourg, Minister for the Environment, Climate and Sustainable Development:

In accordance with European regulations, Luxembourg’s strategy to counter the environmental and social problems caused by invasive alien species has four main components, namely

  1. prevention,
  2. early detection and rapid eradication,
  3. management,
  4. awareness and training.

There are two scenarios:

  1. the establishment of emerging species and any new invasive alien species detected on national territory is prevented;
  2. populations of widely distributed species are controlled, in order to reduce their environmental and social impacts and avoid further spread.

For widespread species, “Invasive Alien Species Action Plans” have been developed, which include the actions to be implemented for each species. All actions thus defined shall be based on the best scientific knowledge and shall take due account of cost-effectiveness, human health, the environment and animal welfare.

A public consultation will be launched shortly for each action plan.
