6-12-2018 MONTE CORONA, VALENCIA - ZOROPSIS SPINIMANA SPIDER (family zoropsidae)


Males of Z. spinimana reach a length around 10–12 mm (0.39–0.47 in), while females are 15–18 mm (0.59–0.71 in) long. This spider resembles a wolf spider, as its eyes are of the same configuration, but unlike wolf spiders, the eyes of Zoropsis spiders are more spread out along the front third of the cephalothorax. The front body (prosoma) is brownish with broad darker markings. The abdomen (opisthosoma) has median black markings. The legs are mainly a speckled brown color.

The abdominal black marking evokes the vampire of the 1922 German silent film Nosferatu, which led to the common German name of the spider, Nosferatu-Spinne.


Zoropsis spinimana is distributed widely in the Mediterranean, but reaches into Russia, and was introduced to the United States, primarily in the San Francisco Bay Area, and the United Kingdom, primarily the London area.

Since the mid-1990s, the species has been sighted along Europe's North-South transport routes, like Lucerne, Basel, Freiburg im Breisgau, Duisburg and Innsbruck. It is not clear why the relatively large spider was not found there earlier, as Mediterranean holidays with mobile homes were popular in the 1970s, and would have provided the spiders with many suitable habitats and transport opportunities. Ecologists assume that climate change enabled the spiders to take hold and reproduce north of the Alps.
