Brief description

Corbicula fluminalis (O.F. Müller, 1774) is a species of freshwater clam, an aquatic bivalve mollusk in the family Cyrenidae. This species is distinct from, but often confused with, the rather similar species Corbicula fluminea. Even though both species are native to Asia, they are both present as introduced species in the United States and Europe, and they are both commonly known as “Asian clams” (Wikipedia contributors 2019).

The original distribution area of Corbicula fluminalis includes the Near East (the type material came from the Euphrates), Central Asia (Uzbekistan) and the Caucasus (Azerbaijan) and North Africa. The animals prefer to live on sandy and muddy river bottoms. Corbicula fluminalis is found today in almost all major Central European rivers, often sympatric with Corbicula fluminea (Wikipedia Editor 2019).

Status and distribution in Luxembourg

In Luxembourg, Corbicula fluminalis (O.F. Müller, 1774) was first found by Klaus Groh on 17 June 1996 in the Moselle river in the municipality of Remich (MNHNL 2000-, Bachmann & Usseglio-Polatera 1999).

An identification sheet of the species has been published by the MECDD in French and German. A flyer about invasive mussels has been published by natur&ëmwelt.

Brief description

Corbicula fluminea (O.F. Müller, 1774) is an inland water, filter-feeding bivalve native to southeast Asia but causing numerous problems in its new range of distribution in the Americas, Europe and Australia. C. fluminea spreads when it is attached to boats or carried in ballast water, used as bait, sold through the aquarium trade and carried with water currents. Its reproductive success and ability to spread rapidly has resulted in this species having one of the most rapid expansions of any non-native species in North America. Before the invasion of the zebra mussel Dreissena polymorpha, in North America, C. fluminea was described by McMahon (1983) as ‘one of the most important molluscan pest species ever introduced into the United States’. Aldridge and Muller (2001) review the potential impacts that the spread of C. fluminea may have on British industry and aquatic systems. In the DAISIE project, C. fluminea is listed on the 100 worst invasive species (CABI 2019).

Status and distribution in Luxembourg

In Luxembourg, Corbicula fluminea (O.F. Müller, 1774) was first documented by Klaus Groh on 17 June 1996 in the Moselle river in the municipality of Remich (MNHNL 2000-). It was expected by 1995 that the species would soon appear in the Moselle (Dhur & Massard 1995: 150).

An identification sheet of the species has been published by the MECDD in French and German. A flyer about invasive mussels has been published by natur&ëmwelt.

Brief description

Chelicorophium curvispinum (G.O. Sars, 1895) (Syn.: Corophium curvispinum) These small crustaceans construct mud tubes on hard materials and are nocturnal filterers. Densities can be extremely high (over 200,000 individuals per m²). They are often associated with seaweeds. With their lifestyle, the crustaceans can provoke important ecological changes in occupied areas.

Brief description

Astacus leptodactylus Eschscholtz, 1823 is a large Eastern European river crayfish. The Galician crayfish grows to a size of 16 to 18 cm, in extreme cases up to 25 cm. The basic colouration is usually light sand-coloured to light brown. It is slimmer than the Noble crayfish and its most conspicuous distinguishing features are the two extremely long, scissor-like claws (Wikipedia contributors 2019).

The crayfish prefers warm, nutrient-rich waters of the lowland or running waters with a slow current. It also lives in very muddy waters (swamp crayfish). If suitable embankments are available, it digs residential caves itself. It has a higher resistance against pollution than the Noble crayfish (Wikipedia contributors 2019).

Originally, the crayfish was resident in the catchment area of the Black Sea and the Caspian Sea. After the crab plague occurred, it was used in some waters of Central Europe, as it was thought that this species was resistant to the crab plague. All current occurrences in Central Europe are based on these stocking measures (Wikipedia contributors 2019).

Status and distribution in Luxembourg

Astacus leptodactylus Eschscholtz, 1823 was first documented by Yoichi Machino in 1999 in ponds in the valley of the Rouderbaach creek (Grevenmacher) (MNHNL 2000-). Another documented occurence near the Belgium border north-west of Doncols might in reality be located in Belgium since the indicated GPS-precision is only 700 m and all other data from 1995 and 1996 are located in Belgium.

Brief description

Vespa velutina nigrithorax du Buysson, 1905 (Hymenoptera: Vespidae) is a hornet of Asian origin which is a generalist predator of medium- to large-sized insects, and scavenger of vertebrate carrion. It has large impacts on Diptera and social hymenopterans, and in particular on honey bees (Apis spp.). It has recently been spreading in Asia (it is an invasive species in South Korea and Japan), and the subspecies V. v. nigrithorax has been accidentally introduced to Europe where it was first recorded from southern France in 2004 (Villemant et al. 2006a: 536, 2006b). Since then it has been found in Spain (2010; López et al. 2011), Portugal (2011; Grosso-Silva & Maia 2012), Belgium (2011, 2016; Barbier & Renneson 2018), Italy (2012; Federazione Apicoltori Italiani 2013), Germany (2014; von Orlow 2014), the Balearic Islands (2015; Leza et al. 2018), the Channel Islands (2016; States of Guernsey Government 2016), the UK (2016; Budge et al. 2017), the Netherlands (2017; Smit et al. 2017), Switzerland (2017; Ebener 2017), Luxembourg (2020; MNHNL, iNaturalist & GBIF, 2020). This invasive species can threaten honey production and native pollinating insects. It may be introduced and transported accidentally with soil associated with plants, garden furniture and pots, timber, vegetables, camping equipment, etc. (CABI 2019).

Further invasions are expected in various countries covering much of Europe.

IAS of Union concern

In 2016, Vespa velutina nigrithorax du Buysson, 1905 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

Vespa velutina nigrithorax du Buysson, 1905 was first recorded in the wild in Luxembourg by Thierry Helminger on 2^nd September 2020: a few individuals on grapes from a vine in a garden (Helminger 2020, Ries et al. 2021).

Before that, in August 2012, the alleged first observation of Vespa velutina in Luxembourg was published in a daily newspaper, which turned out to be wrong, as it contains photos of V. crabro (Back 2012b). 11 days before, the same journalist had already published an article about this Asian hornet species in Belgium (Back 2012a).

By the end of 2021, 28 records of the Asian black hornet in Luxembourg were accessible through the MNHNL-mdata portal (MNHNL, iNaturalist & GBIF 2000-). As was to be expected, the number of observations shows a increasing tendency and reached 68 observations by the end of July 2024.

Outreach

Between the publication of the leaflet in 2016 (DE) and 2017 (FR) and the first observation of the Asian black hornet in Luxembourg on 2020/09/02, 18 reports were sent to the authorities, mostly mistaken for the native Eurasian hornet. 29 reports were sent between the first observation (2020/09/02) and the press release (2020/09/28), 12 were correct. After the press release, 103 reports were sent to date (2020/11/24), of which 11 were indeed reporting the Asian black hornet.

Of the 151 reports of Vespa velutina nigrithorax, 23 were correct and 19 reports without photo or specimen could not be validated. In the remaining reports, the following species have been mistaken for the Asian black hornet: Bombus sp. (1x), Dolichovespula saxonica (1x),Dolichovespula sp. (1x), Polistes dominula (6x), Polistes nimpha (1x), Tabanus bovinus (2x), Vespa crabro (63x,  the native Eurasian hornet), Vespula germanica (31x), Vespula sp. (1x), Volucella zonaria (2x; the hornet mimic hoverfly).

1. Many authors use the English common name “yellow-leeged Asian hornet”, which is wrong in 2 ways: (1) not the legs, but the feet (tarsi) are yellow; (2) there is another subspecies, V. v. flavitarsis Sonan, 1939, which has yellow feet. So a better common name would refer to the subspecies name nigrithorax as Asian black hornet.[↩]
2. Many authors use the French common name “Frelon asiatique à pattes jaunes”, which is wrong in 2 ways: (1) not the legs (“pattes”), but the feet (“tarses”) are yellow; (2) there is another subspecies, V. v. flavitarsis Sonan, 1939, which has yellow feet. So a better common name would refer to the subspecies name nigrithorax as “Frelon asiatique à thorax noir”.[↩]
3. The German common name “Asiatische Hornisse” actually refers to the species Vespa velutina, of which only one, V. v. nigrithorax occurs in Europe. As soon as further subspecies arrive in Europe, such common names will be confusing.[↩]
4. Cf. the reference under the German common name.[↩]

Brief description

Leptinotarsa decemlineata Say, 1824 is a major pest of potato crops. It is approximately 10 millimetres long, with a bright yellow/orange body and five bold brown stripes along the length of each of its elytra. Native to America, it spread rapidly in potato crops across America and then Europe from 1859 onwards. The Colorado beetle has a strong association with plants in the family Solanaceae, particularly those of the genus Solanum e.g.: Solanum nigrum (black nightshade), Solanum melongena (eggplant or aubergine), Solanum dulcamara (bittersweet nightshade), Solanum tuberosum (potato),  Solanum lycopersicum (tomato) and the genus Capsicum (pepper) (Wikipedia contributors 2020).

Status and distribution in Luxembourg

Leptinotarsa decemlineata Say, 1824 was first reported on 23rd June 1936 in Steinsel-Müllendorf, then in Limpertsberg, Mamer and Neuhäuschen in the same year. In 1937 it was reported from Eischen, Finsterthal and Beyren. By 1938 the whole country was infested. The details of this invasion were published by Jos Massard (2000).

The distribution of the species is still widespread all over the country, but populations have sharply decreased, particularly due to the decline of potato production, e.g. from >17000 ha in 1939 to 800 in 1995 (Massard 2000: 212).

Only 14 occurrences of the species are documented in the mdata.mnhn.lu portal, ranging from 1968 to 2019 (MNHNL, iNaturalist & GBIF 2020).

Brief description

Corythucha ciliata Say, 1832 is a species of lace bug in the family Tingidae that is associated with sycamore trees. It originates in the New World, but has been introduced and has spread in Europe. It is a small, whitish insect and feeds on the underside of the leaves, sucking sap. In Europe, C. ciliata was first observed in 1964 in Padova, Italy, and has since spread throughout Southern and Central Europe, infesting the European hybrid plane (Platanus × acerifolia). Although it does not of itself kill trees, in Central Europe it is often found in association with two plant-pathogenic fungi which can kill trees, Apiognomonia veneta and Ceratocystis fimbriata, leading to the hypothesis that it may act as a vector for these fungi (Wikipedia contributors 2019).

Status and distribution in Luxembourg

Corythucha ciliata Say, 1832 is considered widespread in Luxembourg. The sycamore lace bug was first observed in Luxembourg by Svenja Christian in 2010 in Wasserbillig. Schneider & Christian (2013) list 14 localities where the species occurred in 2012, while 17 observations are documented in the mdata.mnhn.lu portal (MNHNL, iNaturalist & GBIF 2020).
