False widow spiders in France
There are a small group of spiders in France that
can be referred to as “False widow spiders”. They are members of the Steatoda species
that bear a resemblance to the much more notorious black widow spiders, (Latrodectus
spp.),
Although these spiders
can cause concern for some people when found in France they are not really
harmful and all these spiders are likely to do is give you a small and
relatively harmless bite. All have a narrow white or lighter band around the
front of the abdomen towards their head but this and other marks often fade
or disappear completely with age.
Rabbit hutch spider - Steatoda bipunctata –
No French common name.
These False Widows are usually chestnut
coloured, although some specimens can be lighter in colour. Frequently there
is a line of tiny cream coloured dots running around the midline of the
abdomen, and there is sometimes a pale line running along the top of the
abdomen from front to back. Found in houses, sheds, out buildings including
rabbit hutches which they seem to be especially attracted to. Extremely low
likelihood of being able to bite a human. Female: 4.5-7 mm
Male: 4-5 mm

Noble False Widow - Steatoda nobilis – No
French common name.
This species originally from the Canary Islands and
Madeira but has been found in France for at least 100 years with a
preference for coastal regions. They have a bulbous abdomen with cream
coloured markings that are often likened to the shape of a skull. Their legs
are reddish-orange. They can be found both inside and outside of buildings.
Bites, should they occur, are no worse than a bee sting. Female 8.5-14
mm Male: 7-10 mm

Cupboard spider - Steatoda grossa –
Stéatode domestique (also known as the dark comb-footed spider, the brown
house spider, or the false widow or false black widow).
The abdomen of this false widow is a red-brown
colour with a crescent shaped stripe at the front and three pale triangular
spots along the top. These markings vary from spider to spider. Sometimes
they're cream coloured and sometimes they're purple or very dark brown.
Found in barns, sheds and houses and for most people the bite from this
spider feels something like a bee sting and isn’t deadly. Females:
6.5-10 mm Males: 4-6 mm

False widow spider - Steatoda paykulliana -
Stéatode toxique
This species is quite characteristic by its black
colour and body with short bristles that make it appear smooth. Only the
abdomen can have other colours and in France we often see a very visible
dorsal abdominal spot: white, yellow, orange or red. There may also be a
clear middle spot on the abdomen with sinuous edges. These warning colours
are related to its toxicity to vertebrates, its potential predators and its
bite can paralyse small mammals for a short period of time. Found in warm
and dry environments, with little or no vegetation. Vineyards are a typical
habitat. Rarely enter houses. Although its bite can be quite painful it
isn’t life threatening for humans. Female: 8-13 mm Male: 4.5-6 mm
