Status and distribution in Luxembourg

Varroa destructor Anderson & Trueman, 2000 was observed in 1985 for the first time in Luxembourg (Meisch 1986). Claude Meisch recalls: “At that time it was a delicate matter, no beekeeper wanted to admit that he had the parasite in his hives. I remember well that I was the first to admit in meetings that I had found Varroa in my hives. Probably Varroa was already widespread in the whole country at that time” (Meisch 2018).

In the 1980s, Varroa spread throughout the country and is nowadays present in every beehive.

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

Status and distribution in Luxembourg

Distribution map of Opilio canestrinii (Thorell, 1876) in Luxembourg. Data source: Recorder-Lux, iNaturalist & GBIF, 2019-12-06.

The first documented occurrence of the species in Luxembourg dates from 2009. It was found by C. Muster on 20th August 2009 in Fort Berlaimont (Municipality of Luxembourg).

Opilio canestrinii is the second most common harvestman in Luxembourg and can be found in every region of the country.

Opilio canestrinii colonises a number of open habitats independently of their moisture. It is very successful in man-made landscapes, even in bigger cities. It is a strong competitor for native species and seems able to displace or even replace those. There are indices that the similar Opilio parietinus, traditionally a common species on house walls, has nearly vanished just a few years after the arrival of O. canestrinii.

Several sources describe this harvestman as a typical species of urban areas. In Luxembourg however, the data provided from different projects show evidence that the species occurs in great number and important percentages even in close-to-nature areas. Since the sixties, O. canestrinii has spread extremely quickly northwards through Europe and has become a more or less common species in his new areas.

Since probably 2000, a completely unknown harvestman started its quick expansion through Central Europe. The species could be classified in the genus Leiobunum, but is different from other European species. It is assumed that it arrived with ships from oversea, probably reaching the Netherlands first. It is still unknown where exactly it came from. 1

The species was first documented for Luxembourg in 2009 (M. Meyer & C. Muster). Big clusters of the species (100-200 animals) have been observed in Rodange and Esch-sur-Alzette in the south of the country. The other findings were individuals or small groups of at most 10 animals. The species is common in the Gutland area while largely missing in the Oesling (Muster & Meyer 2014).

Leiobunum species generally tend to cluster together during daytimes. This behaviour is even stronger pronounced in the species in question. Mass aggregations of several hundreds of individuals have been observed.

Many observations show that in spite of its high reproduction rate this “new” Leiobunum species seems to coexist well with indigenous species and integrates in the native fauna without greater damages. But surely great colonies of the species compete for food with other similar predators.

Brief description

Cheiracanthium punctorium (Villers, 1789) lives in grasslands, preferring tall stalks. The species is rather thermophilous and therefore geographically restricted to the south of Luxembourg. Most observations have been made in dry grassland in the Moselle valley. Climate warming may favour further spread of the species. Being rather similar to several native Cheiracanthium species in its biology, C. punctorium should have no greater influence on the composition of native prey species in a colonised biotope. There may, however, be some competition with similar predators.

The species is known as quite aggressive when disturbed, especially pregnant or egg-protecting females. The chelicerae (fangs) of bigger individuals can easily penetrate through human skin and inject their venom. A bite of C. punctorium is painful and causes itching and swellings, and sometimes stronger reactions like vertigo, nausea, shivering, circulatory collapse and light fever. The symptoms usually decline after 24-30 hours. As the species leads a rather hidden lifestyle, the probability for bites should be rather small. There is a certain, but unfortunately sometimes overstated, media exposure of the species and its venomousness.

Status and distribution in Luxembourg

Brief description

Argiope_bruennichi_Belgrad_060714

Argiope bruennichi in a pasture near Frisange (14.07.2006)

Like many other members of its genus, Argiope bruennichi (Scopoli, 1772) shows striking yellow and black markings on its abdomen. The spider builds a spiral orb web at dawn or dusk, commonly in long grass a little above ground level (Wikipedia contributors 2019a).

Until around 50 years ago, the wasp spider was widespread in southern Europe, and very rarely present in central Europe. Since then the species has greatly enlarged and extended its area. Now it can be found in almost all European countries, as well as in some Asian and North African countries (Wikipedia contributors 2019b). The rapid spread of the species across Europe is generally thought to be facilitated by climate warming.

On sites where this strikingly marked spider occurs, the individual number can be very high. Argiope bruennichi populations might be a certain threat for rare species of their favourite prey and provoke changes in invertebrate communities of conquered sites. However the spider seems to integrate rather well in invaded countries, causing no great damage.

Status and distribution in Luxembourg

Argiope bruennichi (Scopoli, 1772) was first documented by Dr Ernest Feltgen on 24 August 1906 in Lintgen (Weinachter 1906; MNHNL 2000-).

Currently, 188 records of the wasp spider are accessible through the MNHNL-mdata portal (MNHNL, iNaturalist & GBIF 2019).

The species can be considered as widespread in the Grand Duchy.
