Brief description

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, 2021-04-21.

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 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

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).

There is no distribution map available because no data has been entered into the Recorder-Lux database so far (MNHNL, iNaturalist & GBIF 2020).

Brief description

Dermacentor 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

Dermacentor reticulatus Fabricius, 1794 was first documented by Svenja Christian 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 (MNHNL, iNaturalist & GBIF 2020). 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).

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).

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

Posted on2020-09-292020-10-21AuthorChristian Ries

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 on2020-09-212020-10-13AuthorChristian 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.

It 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, 2021-04-21.

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).

Other Trachemys taxa

The pond slider Trachemys scripta (Thunberg in Schoepff, 1792) has three subspecies (Wikipedia contributors 2020b), of which the first two occur in Luxembourg:

Trachemys scripta scripta (Thunberg in Schoepff, 1792), the yellow-bellied slider;
Trachemys scripta elegans (Wied-Neuwied, 1839), the red-eared slider;
Trachemys scripta troostii (Holbrook, 1836), the Cumberland slider. According to GBIF (2019b) this subspecies is already present in Europe (Belgium, The Netherlands, Germany, Poland and Spain).

Brief description

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.
