The Thomisidae are a family of spiders, including about 170 genera and over 2,100 species. The common name crab spider is often linked to species in this family, but is also applied loosely to many other families of spiders. Many members of this family are also known as flower spiders or flower crab spiders.
Philodromidae, also known as philodromid crab spiders and running crab spiders, is a family of araneomorph spiders first described by Tord Tamerlan Teodor Thorell in 1870. It contains over 500 species in thirty genera.
The spider species Tegenaria domestica, commonly known as the barn funnel weaver in North America and the domestic house spider in Europe, is a member of the funnel-web family Agelenidae.
The zebra spider is a common jumping spider of the Northern Hemisphere. Their common name refers to their vivid black-and-white colouration, whilst their scientific name derives from Salticus from the Latin for “jump”, and the Greek scenicus, translating to “theatrical” or “of a decorative place,” in reference to the flashy, zebra-like coloration of the species.
The raft spider, scientific name Dolomedes fimbriatus, is a large semi-aquatic spider of the family Pisauridae found throughout north-western and central Europe. It is one of only two species of the genus Dolomedes found in Europe, the other being the slightly larger Dolomedesplantarius which is endangered in the UK.
Misumena vatia is a species of crab spider with a holarctic distribution. In North America, it is called the goldenrod crab spider or flower (crab) spider, as it is commonly found hunting in goldenrod sprays and milkweed plants. They are called crab spiders because of their unique ability to walk sideways as well as forwards and backwards. Both males and females of this species progress through several molts before reaching their adult sizes, though females must molt more to reach their larger size. Females can grow up to 10 mm (0.39 in) while males are quite small, reaching 5 mm (0.20 in) at most. Misumena vatia are usually yellow or white or a pattern of these two colors. They may also present with pale green or pink instead of yellow, again, in a pattern with white. They have the ability to change between these colors based on their surroundings through the molting process. They have a complex visual system, with eight eyes, that they rely on for prey capture and for their color-changing abilities. Sometimes, if Misumena vatia consumes colored prey, the spider itself will take on that color.
Micrommata virescens, common name green huntsman spider, is a species of huntsman spiders belonging to the family Sparassidae.

The book Svenska Spindlar or Aranei Svecici is one of the major works of the Swedish arachnologist and entomologist Carl Alexander Clerck and was first published in Stockholm in the year 1757. It was the first comprehensive book on the spiders of Sweden and one of the first regional monographs of a group of animals worldwide. The full title of the work is Svenska Spindlar uti sina hufvud-slägter indelte samt under några och sextio särskildte arter beskrefne och med illuminerade figurer uplyste – Aranei Svecici, descriptionibus et figuris æneis illustrati, ad genera subalterna redacti, speciebus ultra LX determinati, and included 162 pages of text and six colour plates. It was published in Swedish, with a Latin translation printed in a slightly smaller font below the Swedish text.
Araneus angulatus is a species of orb-weaving spiders found in the Palearctic realm. It resembles the European garden spider, Araneus diadematus, but has distinctive tubercles on its abdomen. The species was first described in Aranei Svecici in 1757, where it was the first species described, making Araneus angulatus the first scientific name of an animal that is still in use.
Pardosa monticola, or pin-stripe wolf spider, is a species of wolf spider found mainly in Europe. It is found in both dry and humid habitats, and up to an altitude of 2000m.
Xysticus cristatus, the common crab spider, is a European spider from the family Thomisidae.
Phylloneta sisyphia, the mothercare spider, is a species of comb-footed spider from the genus Phylloneta.
Philodromus cespitum is a species of running crab spider in the family Philodromidae. It is found in North America, Europe, North Africa, and parts of the Middle East and Asia. P. cespitum is a foliage-dweller, and is the most abundant species found in European fruit orchards. It acts as a biological control by preying on orchard pests. P. cespitum is a diurnal ambush hunter and preys on aphids, insects, and occasionally competitor spider species. Males court females by tapping on the females’ bodies with their forelegs. They then insert a genital plug into the female during copulation. Unlike in many other spider species, subsequent males can mate with plugged females by removing part of the plug prior to copulation. Males discriminate among females based on virginity and plug size, and can determine these factors using the females’ draglines and plug samples.
Philodromus marxi, the metallic crab spider, is a species of running crab spider in the family Philodromidae. It is found in the United States. They are a sexually dimorphic species. The males are smooth with a metallic sheen and the females present as bristly white and grey.
Philodromus rufus, also known as the White-striped Running Crab Spider is a species of running crab spider in the family Philodromidae. It is found in North America, Europe, Turkey, Caucasus, Russia (Siberia), Central Asia, China, Korea, and Japan.
