Cheiracanthium punctorium (Villers, 1789) lives in grasslands, preferring tall stalks. 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
Cheiracanthium punctorium (Villers, 1789) was first documented in 1988 at the Aarnescht nature conservation reserve near Oberanven, municipality of Niederanven (Hermann 1998).
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.
Currently, 12 records of the species are accessible through the MNHNL-mdata portal; at the previously mentioned Aarnescht, and also at Roudebierg and Haard near Dudelange (MNHNL, iNaturalist & GBIF 2021).
C2 (2+2+2+1) (Ries et al. 2017: 68).
