Brief description

Asian hornet (Vespa velutina)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

Records of Vespa velutina nigrithorax du Buysson, 1905 in Luxembourg. Data source: Recorder-Lux, iNaturalist & GBIF, 2020-10-28.

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

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).

On 4th September 2020, a team of experts tried to locate the nest (Renneson & Schneider 2020). The search was unsuccessful because the crowns of the trees in question could not be well inspected due to the dense foliage. The search will only be successful in autumn. However, the young queens will have already left their nest at that time to look for a wintering place. We must then probably expect an expansion of the population in 2021. The nest in Junglinster was found on 29th September under the eaves of a house. Further observations of the yellow-legged Asian hornet have been since reported from Junglinster (2020-09-09 Cité Kremerich; 2020-09-16 CIPA).

Further observations of the yellow-legged Asian hornet in Luxembourg:

  • 2020/09/09: Ingeldorf, reported by a beekeeper;
  • 2020/09/19: Schifflange, north of the school in Rue Michel-Rodange;
  • 2020/09/21: Esch-sur-Alzette: a nest of yellow-legged Asian hornet has been spotted high in a tree in a private garden near the bus station Wobrécken between rue Général G.S. Patton and rue de la Tuilerie. This same nest was already photographed on 13th September, but reported on 30th September.
  • 2020/09/27: Beckerich;
  • 2020/09/30: Echternach;
  • 2020/10/07: Colmar-Berg, next to the town hall.

Currently (2020/10/07), 15 records of in Luxembourg are accessible through the MNHNL-mdata portal (MNHNL, iNaturalist & GBIF 2020).

The European hornet (Vespa crabro) and several social wasps (Vespula spp.) are well established in Luxembourg and they occupy potential niches suitable for the yellow-legged Asian hornet. Nico Schneider (2018) wonders if this might be part of the explanation why the yellow-legged Asian hornet hadn’t established itself earlier in Luxembourg in the last years.

Risk assessment

ISEIA protocol

Following its discovery in Luxembourg on 2nd September 2020, the species has been reassessed on 3rd September to C1 (3+1+1+1) by Christian Ries. Assessment before the appearance of the species in Luxembourg: C0 (3+1+1+1) (Ries et al. 2017: 69).

Harmonia+ protocol

Not assessed yet.

Worldwide distribution

Outreach

Between the publication of the leaflet in 2016 (DE) and 2017 (FR) and the first observation of the yellow-legged Asian hornet in Luxembourg on 2020/09/02, 18 reports were sent to the authorities, mostly mistaken for the native European hornet. 28 reports were sent between the first observation (2020/09/02) and the press release (2020/09/28), 11 were correct. After the press release, 98 reports were sent to date (2020/10/27), of which 5 were indeed reporting the yellow-legged Asian hornet.

Of the 144 reports of Vespa velutina nigrithorax, 20 were correct and 18 reports without photo or specimen could not be validated. In the remaining reports, the following species have been mistaken for the yellow-legged Asian hornet:

  • Bombus sp. (1x)
  • Dolichovespula saxonica (1x)
  • Dolichovespula sp. (1x)
  • Polistes dominula (5x)
  • Polistes nimpha (1x)
  • Tabanus bovinus (2x)
  • Vespa crabro (62x, the native European hornet)
  • Vespula germanica (30x)
  • Vespula sp. (1x)
  • Volucella zonaria (2x; the hornet mimic hoverfly)

Press release (2020-09)

Press release of 28 September 2020: “First detections of the yellowlegged Asian Hornet in Luxembourg” (FR & DE)

Leaflet (2016)

In spring 2016 the Department for the Environment of the Luxembourg Ministry of sustainable development and infrastructures published a leaflet in German about Vespa velutina, in co-operation with the Nature and Forestry Administration, the National Museum of Natural History, natur&ëmwelt and the national bee-keeping association. A French version was produced in spring 2017. It can be downloaded here in PDF format (~400KB each).
