Brief description

Potamopyrgus antipodarum (Gray, 1843) is an aquatic snail native to New Zealand. It has been introduced to Europe, North America, Australia, Iraq, Turkey and Japan. In several ecosystems it is considered invasive because it becomes highly abundant, impacting the structure and function of the invaded ecosystems. Females are parthenogenetic, meaning they can reproduce without males, so a population can be founded by a single female. Most the non-native populations are female. There can be up to six generations per year, with an average number of 230 offspring per adult per year. P. antipodarum can also tolerate desiccation for several days, which allows for rapid spread (such as by birds and fishing tools) throughout different aquatic ecosystems. In several countries, including Spain, USA and Australia, it is considered as an invasive species (CABI 2019).

Status and distribution in Luxembourg

Potamopyrgus antipodarum (Gray, 1843) was first documented by Gerhard Weitmann and Klaus Groh on 17 June 1996 in the Moselle river in the municipality of Remich (MNHNL 2000-).

Currently, 52 records of the New Zealand mud snail are accessible through the MNHNL-mdata portal (MNHNL, iNaturalist & GBIF 2019).

Brief description

Sinanodonta woodiana (Lea, 1834) is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels. The Chinese pond mussel can reach sizes of up to 30 cm and an age of 12–14 years. Yet, they can reproduce in their first year while only 3–4 cm in size. This large freshwater mussel is a habitat generalist with high silt tolerance. It is established worldwide despite having, like all unionid mussels, an obligatory parasitic stage (glochidium), which must encyst on host fish. The species is a broad host generalist, which can complete its development on all fish species tested, both coinvasive and native. The presence of S. woodiana can seriously influence indigenous unionid populations. Sinanodonta woodiana’s great success is attributed to importation and commercialization of Asian carp, its native host. S. woodiana was introduced in Tuscany both inadvertently, and for artificial pearl production. The species is also sold in garden centers as biofiltration for artificial ponds (CABI 2019).

Status and distribution in Luxembourg

Sinanodonta woodiana (Lea, 1834) has not yet been observed in Luxembourg (MNHNL, iNaturalist & GBIF 2020).

Brief description

To date, D. polymorpha has been the most aggressive freshwater invader worldwide. Dreissenids are the only freshwater bivalves that attach to hard substrates in high densities and have a planktonic larval stage. This life history facilitates their abilities as invaders, and allows them to become enormously abundant when introduced into a new water body. Once introduced their populations can grow rapidly, and the total biomass of a population can exceed 10 times that of all other native benthic invertebrates. D. polymorpha is native to the drainage basins of the Black, Caspian and Aral Seas. During the nineteenth century its range has expanded westward to most of western Europe, the UK, and North America, where it is found in the Great Lakes and all major river drainages east of the Rocky Mountains and causes multiple economic impacts on fisheries, aquaculture, water attractions and aquatic transport (CABI 2019).

Status and distribution in Luxembourg

In Luxembourg, Dreissena polymorpha (Pallas, 1771) was first mentioned by Victor Ferrant in 1892 as occurring in the Moselle river (Ferrant 1892; Dhur & Massard 1995; MNHNL 2000-).

An identification sheet of the species has been published by the MECDD in French and German.

Brief description

Eriocheir sinensis H. Milne-Edwards, 1853 is a migrating crab which has invaded Europe and North America from its native region of Asia. During its mass migrations it contributes to the temporary local extinction of native invertebrates. It modifies habitats by causing erosion due to its intensive burrowing activity and costs fisheries and aquaculture several hundreds of thousands of dollars per year by consuming bait and trapped fish, as well as by damaging gear (GISD 2019).

IAS of Union concern

In 2016, Eriocheir sinensis H. Milne-Edwards, 1853 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 it’s unintentional introduction or spread.

Status and distribution in Luxembourg

There is no distribution map available because no data has been entered into the Recorder-Lux database so far (MNHNL, iNaturalist & GBIF 2019).

Eriocheir sinensis H. Milne-Edwards, 1853 was first documented in Luxembourg in 1978 by Claude Meisch who found one individual in a pond of the Haff Réimech nature conservation reserve, municipality of Schengen (Meisch 1978): “It can be regarded as relatively common in the Moselle valley. A single specimen was found in the pond area. It must be regarded as an aberration, since the ponds do not correspond to its normal location”.

Field research by Dhur and Massard in the years 1992-1993 did not find Eriocheir sinensis in the ecosystem of the border Moselle (Dhur & Massard 1995): “It seems likely that currently the species, even if its presence seems confirmed for the period before 1960, no longer populates the waters of the Luxembourg Moselle. A call to fishermen in 1994 (Massard 1994)¹ for them to report a possible presence of Eriocheir did not produce any results. In fact, after its expansion phase, Eriocheir has become considerably scarcer over the past forty years in most of the colonised areas of northern France and the Benelux (Vigneux et al. 1993). No E. sinensis stations are indicated in Lorraine by Vigneux et al. (1993), neither for the period before 1960 nor for the one after.”

On 4 March 2020, two adult crabs of the species Eriocheir sinensis (1 male and 1 female) were found by an inhabitant of the ‘Petite rue du Moulin’ in Esch-sur-Alzette.The crabs were brought to the National Museum of Natural History.

Brief description

Stictocephala bisonia Kopp & Yonke, 1977 is a species of treehopper belonging to the subfamily Membracinae. It is also sometimes classified as Ceresa bisonia. This species is native to North America, but now it is widespread throughout southern Europe and it is also present in the Near East and in North Africa. Both adult and immature buffalo treehoppers feed upon sap using specialized mouthparts suited for this purpose. Black locust, clover, elm, goldenrod, and willow are among their favorite food sources. It is also an occasional pest of fruit trees and is harmful to young orchard trees, especially apple trees. It has become an invasive species in some parts of Europe (Wikipedia contributors 2020).

Status and distribution in Luxembourg

Stictocephala bisonia Kopp & Yonke, 1977 was first documented by Robert Biedermann on 15th September 2002 near Remerschen, municipality of Schengen (MNHNL 2000-).

Currently, 61 records of the buffalo treehopper in Luxembourg are accessible through the MNHNL-mdata portal, most of them in the Gutland, the southern half of the country (MNHNL, iNaturalist & GBIF 2021).

Brief description

Stephanitis takeyai Drake & Maa, 1955 is a pest insect on plants of the genus Pieris, especially Pieris japonica, the Japanese andromeda. It originated in Japan with its host plant but has since been introduced to other areas of the globe. The andromeda lace bug is about 3 millimeters in length. It has a characteristic rounded pronotum, lacy black and white wings, and shiny gold highlighting. The bug produces mottling on the leaves of the plant, and heavy infestations can cause the leaves to drop in large numbers, stunting the plant’s growth. Both nymph and adult forms damage the leaves by piercing them to suck the juices, and leave dark frass on the undersides of the leaves. Damage is worst on plants that grow in full sun (Wikipedia contributors 2018).

“Stephanitis takeyai is an invasive Tingidae native to Japan. It was introduced to Europe in 1994 through the plant trade in the Netherlands with its feeder plant Pieris japonica (Aukema 1996). It reached Germany in 2002 (Baufeld 2002), Belgium in 2003 (Aukema et al. 2005) and France in 2004 (Streito 2006)” (Schneider 2020).

Status and distribution in Luxembourg

Stephanitis takeyai Drake & Maa, 1955 was first found on 24^th June 2019 in the kitchen of a private house in Roeser. The often open door of this kitchen communicates with a garden in which grows Pieris japonica (the Japanese andromeda), the host plant of the Andromeda lace bug (Schneider 2020: 100).

Brief description

Sceliphron curvatum (F. Smith, 1870) is a species of hymenopteran insects, and more precisely a mason wasp, of the family Sphecidae. It is a species native to the mountainous regions of Asia, particularly the Himalayas, and has recently appeared in Europe (early 1980s). It is locally invasive, including in France in the South-East, where it could perhaps compete with native species (Wikipedia contributors 2019).

Status and distribution in Luxembourg

Sceliphron curvatum (F. Smith, 1870) was observed for the first time in Luxembourg on 15th July 2011 near Echternach (Schneider et al. 2014).

Three further observations in 2023 seem to indicate that the species is establishing in Luxembourg (MNHNL, iNaturalist & GBIF, 2023): 2023-07-22 in Soleuvre (Nico Pantaleoni on iNaturalist); observations of mud cells on window frames on 2023-08-09 and 2023-08-22 by Florence Felten-Ries in Bous/Erpeldange and Hollerich (Luxembourg city), each mud cell being provided with 20 to 25 spiders.

Brief description

Pulvinaria regalis Canard, 1968 is a species of scale insect in the family Coccidae. Although it is commonly known as the horse chestnut scale, it affects other trees besides horse chestnuts as well as many species of woody shrubs. Adults are normally all female and produce eggs by parthenogenesis. The insects are thought to have originated in Asia but arrived in Europe in the second half of the twentieth century. Pulvinaria regalis is known to be hosted by 65 species of plant from 25 families. The main species of tree which act as hosts for this scale insect are horse chestnut, sycamore, maple, lime, elm, magnolia, bay and dogwood (Wikipedia contributors 2019)

Status and distribution in Luxembourg

Pulvinaria regalis Canard, 1968 was first documented together with P. hydrangeae by Nico Schneider and Sandra Tanson in the year 2000 in Luxembourg City (Bonnevoie), Dudelange and Esch-sur-Alzette (Schneider & Tanson 2003: 87).

Currently, 29 records of the horse chestnut scale are accessible through the MNHNL-mdata portal (MNHNL, iNaturalist & GBIF 2020).

Other Pulvinaria taxa

Pulvinaria vitis (L.) is the only native species of the scale louse genus Pulvinaria. Recently, three other species of this genus, P. floccifera (Westwood), P. hydrangeae (Steinweden) and P. regalis Canard, have migrated to Luxembourg, where they have become established without any problems (Schneider & Tanson 2003: 87).

Brief description

Phyllonorycter robiniella Clemens, 1859 is a moth of the family Gracillariidae. It is native to North America (where it is distributed from Ontario south to South Carolina and west to Missouri and Texas), but is an introduced species in Europe, where it was first reported near Basel, Switzerland, in 1983. Later, it was also reported in France, Germany, northern Italy (1988), Austria (1989), and Slovakia (1992). It spread gradually through Austria, reaching Hungary in the mid 1990s. The larvae feed on Robinia pseudoacacia, Robinia viscosa and Robinia hispida. They mine the leaves of their host plant (Wikipedia contributors 2020).

Status and distribution in Luxembourg

“This species is native to North America and was introduced into Europe. It was first identified in 1983 in Basel, Switzerland (Huemer et al. 1992). Since then it has colonized all countries of Central and Western Europe, and in Luxembourg the species can be found everywhere on Robinias. Since 2003 it has been found in several places in Luxembourg (N. Schneider, pers. comm.). In the past it has been reported from Wintringen (Schneider 2004), from Bonneweg and Düdelingen (Schneider & Walisch 2009), as well as from Remerschen, Esch/Alzette and Luxembourg-Kirchberg (Ries 2016). The caterpillar lays conspicuous white blanks on the underside of the leaves of Robinia (Robinia pseudoacacia)” (Hellers 2017: 140-141).

4 observations are documented in the mdata.mnhn.lu portal (MNHNL, iNaturalist & GBIF, 2020).
