Steatoda nobilis is a spider in the genus Steatoda, known in the United Kingdom as the noble false widow,[ as it superficially resembles and is frequently mistaken for the black widow and other spiders in the genus Latrodectus. It is often referred to as the false widow, although "false widow" is a more general term applied to a wider group of species with this resemblance. It is a moderately medically significant spider, with most bites resulting in symptoms similar to a bee or wasp sting.[Some bites may cause more significant harm, partly due to bacteria from the spiders. spotted all year round, both indoors and outdoors in a variety of habitats including roadside cuttings, and demolished buildings. The spiders prey on both invertebrates and small vertebrates using an "attack wrap" strategy where silk is wrapped around the victim.

Steatoda nobilis is native to Madeira and the Canary Islands from where it is thought to have spread to Europe, and continued to spread to other parts of the world including the United States, Chile and Colombia. They are considered to be one of the world's most iinvasive species of spider.[10]

The giant house spider has been treated as either one species, under the name Eratigena atrica, or as three species, E. atrica, E. duellica and E. saeva. As of April 2020, the three species view was accepted by the World Spider Catalog. They are among the largest spiders of Central and Northern Europe. They were previously placed in the genus Tegenaria. In 2013, they were moved to the new genus Eratigena as the single species Eratigena atrica.[2] In 2018, the three separate species were restored.[3]The bite of these species does not pose a threat to humans or pets, and they are generally reluctant to bite, preferring instead to hide or escape.

The two sexes do not differ in coloration or markings. Its coloration is mainly dark brown. On its sternum is a lighter marking, with three light spots on each side that form an arrow-like shape pointing toward the head of the spider. The opisthosoma features a lighter middle line with six "spots" on each side. The giant house spider has the same coloration as the domestic house spider, Tegenaria domestica; it has earthy tones of brown and muddy red or yellow. They also have conspicuously hairy legs, palps, and abdomen. The female body-size can reach 18.5 millimeters (0.73 in) in length, with males having a slightly smaller body at around 12 to 15 millimeters (0.47 to 0.59 in) in length. The female leg-span is typically around 45 millimeters (1.8 in). The leg span of the male is highly variable, with spans between 25 and 75 millimeters (0.98 and 2.95 in) being common.[.

Its eight eyes are of equal size and are arranged in two rows. As the eyes contain fewer than 400 visual cells, E. atrica can probably only distinguish light and dark

The Spitting Spider  -This slow moving species acquired the common name of spitting spider from its method of capturing prey. A sticky substance is squirted from the chelicerae in an oscillating movement onto the prey from a distance of as much as 10 mm or more, sticking it to the surface before it is despatched with a bite on the leg and removed from the gum before consumption. The squirting of gum is also used as a defensive measure against other spiders. Scytodes thoracica is limited within Britain to houses and other heated buildings where it may take as long as two or three years for the female to reach maturity. Adults can probably be found throughout the year though our very limited phenology data suggest a peak in July.

Some species exhibit presocial behaviour, in which mature spiders live together and assist the young with food.[7]

The Cupboard Spider - (Steatoda grossa)bipunctata, with purplish-brown, evenly-coloured dark legs or with lighter stripes. They have an abdomen pattern of two clear triangles and lateral bars, but these are often dim or missing in the darkest specimens.There are three very similar species of false widow spider that are likely to be found in or around our homes: Steatoda bipunctata (known as the rabbit hutch spider), Steatoda grossa (known as the cupboard spider) and Steatoda nobilis (known as the noble false widow).

The noble false widow is the largest of these three species, with males typically growing to body lengths of up to 10mm and females up to 14mm. Noble false widows are not native to the UK, but are thought to have arrived from the Canary Islands in banana boxes in the late 1800s. Populations became established along the south coast and have since spread north, likely aided in their expansion by global warming. The other two species are both native to the UK.

False widow spiders often appear in news stories about spider bites, typically in early autumn. However, confirmed cases of false widow bites are rare. Only the two larger species of false widow, the cupboard spider and the noble false widow, are likely to be able to bite through human skin at all. The spiders are not aggressive towards people, and generally don’t bite unless roughly handled; most recorded bites occur because of people accidentally touching a spider which then reacts defensively.

In the extremely rare confirmed cases where a noble false widow has bitten someone, the bite has been compared to a wasp sting. In even rarer cases, the bite may cause a person to feel unwell for a short time.

The harmless Mouse spider in the UK has nothing in common with the slightly venomous Australian Mouse spider from the Missulena genus. The European species is widespread in Britain and is mostly spotted in the autumn.

• Appearance: The females are about 11mm in size, whereas the male adults are about 9mm long. The name comes from their hairy abdomen, which is velvety and grey-brown in colour. They have stocky, strong legs and a brown body.
• Feeding habits: They love to scavenge on dead insects, but will also venture up on your ceiling and walls to look for potential prey.
• Habitat: Outdoors, they will hide in hollows and under the bark of trees, also in crevices in outside buildings. In your home, the Mouse spider will, again, prefer to hide and lay eggs somewhere dark and hidden.
• Mouse Spiders are harmless - The bite from a mouse spider is likely to be less painful than a wasp sting

Jumping Spiders

There are nearly 40 species of Jumping Spider in the UK. Jumping Spiders are small and stocky in build with short legs and are recognised by their square-fronted carapaces and large forward-facing eyes. Jumping Spiders do not build webs to catch their prey. As their name suggests they have the ability to jump and launch themselves through the air at great speed. They can use this ability to 'jump' to catch prey or evade predators. Most Jumping Spider species in the UK are diurnal and prefer dry sunny locations. They can often be readily identified by their short jerky movements when walking. 

Jumping Spiders have four pairs of eyes, two of which are front facing. One pair of the front facing eyes are extremely large. These huge front-facing eyes are used for gathering a detailed image enabling the spider to identify potential prey and judging distance when jumping onto their prey. Before the spider jumps it attaches a web line which it can use to enable it to return to the same spot again. Zebra Jumping Spiders are small with a maximum body-length of 5-7mm. They are stocky in build with short, thick legs. If you approach a Jumping Spider, it will often lift its head and follow your movements closely with its big eyes
