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).

Brief description

Lasius neglectus Van Loon, Boomsma & Andrásfalvy, 1990 is a polygynous, sometimes invasive, ant of the genus Lasius. The ant was identified in 1990 after establishing a colony in Budapest, Hungary. Superficially, they are similar in appearance to the common black garden ant, Lasius niger, but have significantly different behavioural patterns, particularly in the social structure within colonies. Lasius neglectus is believed to be prey for several animals and insects, specifically Clytra laeviuscula and some Picidae family birds.

Lasius neglectus can outnumber native European varieties of ant by 10 to 100 times in infested gardens and, as such, has been considered a pest in many central European countries. The species has spread as far as Jena in Germany, Ghent in Belgium and Warsaw in Poland. A colony has been reported in Hidcote Bartrim, Gloucestershire in England, where it demonstrates an affinity for outdoor electrical fittings where it may constitute a fire risk (Wikipedia contributors 2020).

Brief description

Hyphantria cunea (Drury, 1773), native to North America, is a moth in the family Erebidae known principally for its larval stage, which creates the characteristic webbed nests on the tree limbs of a wide variety of hardwoods in the late summer and fall. It is considered a pest but although unsightly, does not harm otherwise healthy trees. It is well known to commercial tree services and arboriculturists. The adult fall webworm has a wingspan of approximately 30 mm and is generally white-colored, although some individuals may have dark-colored marks (Wikipedia contributors 2020).

Status and distribution in Luxembourg

So far, Hyphantria cunea (Drury, 1773) has been documented only once, in 2014 in the Kirchberg district in Luxembourg City (Source ?).

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

Harmonia axyridis (Pallas, 1773) lives in a very wide range of habitats: farmlands, orchards, wetlands, and forest margins. It seems to avoid deep forest habitats. H. axyridis is a strong intraguild predator and is able to displace native ladybird species, hence the population collapse of the two-spot ladybird Adalia bipunctata is largely attributable to its rapid expansion in North America and Europe. The Harlequin ladybird is also known to invade houses in winter (Adriaens et al. 2007).

Status and distribution in Luxembourg

Harmonia axyridis (Pallas, 1773) was observed in Luxembourg for the first time on 18th September 2004 by Nico Schneider at Schleifmillen, municipality of Junglinster (Schneider & Loomans 2006).

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

Brief description

Graphocephala fennahi D.A. Young, 1977 is a species of leafhopper native to the United States. Its common name derives from it feeding on the sap of rhododendrons. The species was introduced to Great Britain in the 1930s and continental Europe in the 1970s. There has been suggestion that the rhododendron leafhopper contributes to the spread of a rhododendron fungus through Europe (Wikipedia contributors 2020).
