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).

Brief description

Phyllonorycter medicaginella (Gerasimov, 1930) is a moth of the family Gracillariidae. It is found from Denmark and Poland to Belgium, the Alps, Bulgaria and Ukraine. The larvae feed on Medicago falcata, Medicago lupulina, Medicago sativa, Melilotus alba, Melilotus officinalis, Ononis spinosa, Trifolium dubium, Trifolium campestre and Trifolium repens. They mine the leaves of their host plant (Wikipedia contributors 2020).

Status and distribution in Luxembourg

Phyllonorycter medicaginella (Gerasimov, 1930) was first documented by Marcel Hellers on 9 October 2011 at Grousse Mies in Bissen (Hellers 2017: 139).

This species is very rare depending on the year, and then again frequent. It lives on lucerne (Medicago sativa). Here it forms large blister mines on the underside of the leaves. Unlike most other species of this genus, the butterflies hatch in autumn and overwinter as imago. This seems to be a survival strategy of the animals, as the delicate leaves would decay in winter and the caterpillars would have to hibernate unprotected (Hellers 2017: 139-140).

Brief description

Phyllonorycter leucographella (Zeller, 1850) is a moth of the family Gracillariidae. It is native to southern Europe (Mediterranean regions of France, Spain, Greece, Albania, Russia (Crimea), Turkey, and the southern part of former Yugoslavia where its principal host plant is native) and was probably introduced accidentally into several countries in western Europe on transported plant material (Wikipedia contributors 2020).

The larvae mainly feed on Pyracantha coccinea, the European species of firethorn, but have also been recorded on Crataegus species.

Status and distribution in Luxembourg

Phyllonorycter leucographella (Zeller, 1850) was observed in Luxembourg for the first time on 25th April 1998 by Marcel Hellers at the railway station of Ettelbruck (Hellers 2017: 139).

“This species has been introduced with the forage plant. It lives on an ornamental plant, the firethorn, Pyracantha coccinea, on whose leaves the caterpillars lay conspicuous mines. The species can be found everywhere in our villages in gardens and parks around the firethorn. It has already been reported from Luxembourg (Schneider 2006). In Düdelingen, Haard, mines of these caterpillars have been found on Sorbus torminalis, although the service tree, in contrast to the firethorn, has no wintergreen leaves in which the caterpillars of the summer generation of the firethorn leaf miner moth spend the winter (N. Schneider, pers. comm.)” (Hellers 2017: 139).

3 observations are documented in the mdata.mnhn.lu portal (MNHNL, iNaturalist & GBIF, 2021).

Brief description

Obolodiplosis robiniae (Haldeman, 1847) has been recorded for the first time in Italy (Veneto) and in Europe in July 2003. Its natural distribution includes the eastern USA. The larvae of O. robiniae produce galls on the leaflets of Robinia pseudoacacia. In particular, the margins of leaflets are rolled downwards. Symptoms are recorded more commonly on the apical shoots (Duso et al 2005).

In 2004 the black locust gall midge was found in Czech Republic and Slovenia, in 2006 in Hungary, Slovakia, Serbia and Montenegro and also in Germany. In Belgium, the first galls were found in 2005, in Luxembourg in 2006, in France, Romania, Poland, Switzerland and England in 2007 and in the Netherlands in 2008 ((Schneider & Walisch 2009: 261).

Status and distribution in Luxembourg

In Luxembourg, Obolodiplosis robiniae (Haldeman, 1847) was first observed in 2006 by F. Feitz in Remich (Schneider & Walisch 2009: 161).

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

Brief description

Info from Proess 2010: “Meconema meridionale (Costa, 1860) is an Adriato-Mediterranean faunal element. Its closed distribution area originally extended from Sicily to the Alps and from the western parts of southern France (Hérault department) to Slovenia and Istria (Detzel 1998). Since about 1960, the species has spread strongly northwards and has now reached England as well as Belgium and the Netherlands (Kleukers et al. 2004) (Jennings 2005).”

“The purely carnivorous feeding species colonises different shrub and tree species such as maple, oak, lime, hornbeam, privet, chestnut or horse chestnut. Evidence is also found, however, in climbing and climbing plants. The eggs are preferably laid in the cracked bark of trees.”

Status and distribution in Luxembourg

In Luxembourg, Meconema meridionale (Costa, 1860)  was first observed by M. Weitzel on 2nd September 2006 in Wasserbillig (Municipality of Mertert). Other observations were made by M. Weitzel (August 2009 in Mertert and Wasserbillig), R. Proess (October 2009 in Heisdorf) and Marc Meyer (October 2009 in Luxembourg-Grund) (Proess 2010).

Brief description

Linepithema humile (Mayr, 1868) is one of the most invasive and problematic ant species in the world according to the Invasive Species Specialist Group (www.issg.org/database). Native to South America, it has spread worldwide in areas with Mediterranean-type climates usually associated with disturbed habitats as a result of human commercial activities. Its capacity to tolerate a wide range of abiotic conditions, its generalist dietary requirements and its unicolonial organization, which lead to the formation of large supercolonies, allow the species to spread easily and occupy a wide range of areas. In these areas, L. humile has impacted native ant faunas leading to changes in arthropod communities, ant-vertebrate interactions and ant-plant relationships. Its presence has also had economic effects, such as damage to infrastructure, and negative effects on crops and plantations due to its mutualistic interactions with hemipterans, which can affect the growth and production of the host plant (CABI 2019).

Status and distribution in Luxembourg

The species hasn’t been observed in Luxembourg so far (MNHNL, iNaturalist & GBIF, 2020).

Risk assessment

Brief description

Leptoglossus occidentalis Heidemann, 1910 is a North American bug native of the Rocky Mountains. It was observed for the first time in October 1999 in Europe, near Vicenza in Italy. Following several introductions to our continent, the expansion of the species has been very rapid. Leptoglossus occidentalis was reported in Switzerland in 2002, in Slovenia and Spain in 2003, in Croatia and Hungary in 2004, in Austria in 2005 and in France in 2006. In 2007 it was reported in Germany, the Czech Republic, the United Kingdom and Belgium as well as in Poland, and in 2008 in Bulgaria, Montenegro, Serbia and the Netherlands (Schneider 2010: 115).

Status and distribution in Luxembourg

The species was first observed in Luxembourg by Guy Marson in Steinfort on 9th October 2009 (Schneider 2010: 116).

It is widely distributed by now.
