Brief description

Sceliphron fg01Sceliphron 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

Records of Sceliphron curvatum (F. Smith, 1870) in Luxembourg. Data source: Recorder-Lux, iNaturalist & GBIF, 2024-05-22.

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.
