Cyclosa conica is a small spider with no common name. It is an orb weaver, and it is easily recognized by the way it strings together the dead bodies of insects and other debris and hangs it near the center of its web. It hides on this string of debris, and its natural coloration makes it extremely difficult to see until it moves. One of its defenses against predators is to blend in with this debris and to feign death when disturbed. These spiders are small; the females range from 5.3 mm to 7.5 mm, and the males range from 3.6 mm to 4 mm.

Gnaphosa borea is a ground spider species with Holarctic distribution. It is found in boreal forests in Russia, in the United States and in Canada.

Gnaphosa muscorum is a ground spider species with Holarctic distribution. The subspecies G. muscorum gaunitzi is found in Sweden and Russia.

Misumena vatia is a species of crab spider with holarctic distribution. In North America, it is called the goldenrod crab spider or flower (crab) spider It is commonly found hunting in goldenrod sprays in the autumn.

As of September 2019 it contains three species with a holarctic distribution, including Greenland: O. lundbecki, O. ohlerti, and O. thaleri. A 2019 genetic study proposed to synonymize this genus with Heterotheridion; however, the evidence was based predominantly on COI barcoding, which is a useful tool for separating species, but is less useful for determining higher taxa.

Ozyptila praticola is a species of crab spider found throughout Europe and the Middle East. Females reach up to 4 mm, males grow up to 3 mm. Both sexes are of a dark reddish brown. It hunts primarily in the undergrowth, but can also be found under the bark or on the lower branches of trees. This is also where the female deposits and guards its egg sac.

The zebra spider is a common jumping spider of the Northern Hemisphere. Like other jumping spiders it does not build a web. It has a particularly large pair of forward facing eyes that help it to locate and stalk its prey before pouncing on it. Their common name refers to their vivid black-and-white colouration, whilst their scientific name derives from Salticus from the Latin for “dancing”, in reference to their agility, and the Greek scenicus, translating to “theatrical” or “of a decorative place,” in reference to the flashy, zebra-like coloration of the species.
