Ero cambridgei is a pirate spider species with Palearctic distribution. It is notably found in Lithuania. [2]
Adult males have a body length of 2.5–3.0 mm (0.10–0.12 in), females 2.5–3.5 mm (0.10–0.14 in). The carapace is pale brown, with a dark brown to black ocular region. It bears a dark brown median line, which usually widens at the junction between the head and thoracic area, as well as dark brown marginal lines which vary in width. It has a distinctive central dome, and strong spines are usually present towards the head area. The abdomen is globular in shape, with downward facing spinnerets and a pair of flattish tubules on the dorsal side. It is creamy brown to orange in colour, and mottled with black, especially towards the anterior. The legs are pale brown, with clear dark annulations. The metatarsi of the front two pairs of legs are curved and, along with the tarsi, bear strong spines. The front two pairs of legs are distinctly longer than the rear two. They have eight eyes, with the median eyes forming a rough square and the lateral eyes being clustered to either side. [3]
They are found on bushes, trees and low vegetation in a variety of habitats, especially in areas where other spiders, their main prey, are found. [3]
Austracantha is a genus of spider with a single species, Austracantha minax, commonly known as the jewel spider or the Christmas spider. It is a member of the family Araneidae and is endemic to Australia. They are relatively small spiders, reaching a maximum total body length of only around 12 mm (0.47 in) for females, and 5 mm (0.20 in) for males. Their abdomen has six distinctive projections ("spines") that makes them easy to identify. They are predominantly a shiny black, with variable white, yellow, and orange patterns. Melanistic forms also occur during autumn. They are facultatively gregarious, and can be found in large aggregations of overlapping orb webs. They feed on small flying insects that get entangled in their webs. They are harmless to humans, though the webs can be a nuisance for bushwalkers. They are most abundant during the summer months.
Philaeus chrysops is a species of jumping spider (Salticidae).
Uloborus walckenaerius, also known as the feather-legged spider, is a cribellate spider in the family Uloboridae. Like all spiders in this family, they do not have venom glands and immobilize their prey with over 140 metres of thread. They are named in honor of Charles Athanase Walckenaer.
Segestria senoculata, sometimes known as the snake-back spider, is a species of spider belonging to the family Segestriidae. It has a Palearctic distribution.
Enoplognatha ovata, the common candy-striped spider, is a species of spider belonging to the family Theridiidae. Their scientific name derives from the latin word 'ovatus' which means egg-shaped. Despite its small size, this is a formidable predator which can prey on insects many times its size.
Zygoballus sexpunctatus is a species of jumping spider which occurs in the southeastern United States where it can be found in a variety of grassy habitats. Adult spiders measure between 3 and 4.5 mm in length. The cephalothorax and abdomen are bronze to black in color, with reddish brown or yellowish legs. The male has distinctive enlarged chelicerae and front femora. Like many jumping spiders, Z. sexpunctatus males exhibit ritualized courtship and agonistic behavior.
Rugathodes sexpunctatus is a minute species of spider in the family Theridiidae, the cobweb or tangle-web spiders. This family includes the medically important genus Latrodectus—the widow spiders. The species in the genus Rugathodes are too small to be dangerous to humans. Very little is known about most species in this genus.

Araneus mitificus, commonly known as the kidney garden spider or pale orb weaver is a species of orb-weaver spider found in South, East, and Southeast Asia.
Progradungula otwayensis, commonly known as the odd-clawed spider, is a species of cribellate spider endemic to the Great Otway National Park of Victoria, Australia. It is one of only two species in the gradungulid genus Progradungula.
Hyptiotes paradoxus, also known as the triangle spider, is a cribellate orbweaver in the family Uloboridae.
Afraflacilla roberti is a species of jumping spider in the genus Afraflacilla that is found in Kenya. The spider was first defined in 2011 by Wanda Wesołowska. She originally placed the species in the genus Pseudicius, but Jerzy Prószyński moved it in 2017 to Afraflacilla on the basis of shape of its copulatory organs. The species is named after Robert Jackson, the collector who found the first example. The spider is small, with a cephalothorax between 1.7 and 1.6 mm long and an abdomen between 1.7 and 2.4 mm long. The female is larger than the male. The carapace is a dark brown elongated oval with a black eye field covered in white hairs. The abdomen is blackish-brown and is marked by two pairs of white patches and a small number of faint chevrons at the very rear. Some female examples have a generally featureless dark abdomen and others have additional small rounded patches at the edge. Some have light stripes to the front of the abdomen. The spider has yellow legs, apart from the front pair, which are brown, longer and stouter. It stridulates using its legs and carapace. Afraflacilla roberti can be differentiated from other species in the genus by its copulatory organs. The male has a long thin tibial apophysis. The female has narrow coiled insemination ducts.
Afraflacilla refulgens is a species of jumping spider in the genus Afraflacilla that lives in Zimbabwe. It lives in loose conglomerations in nests of white papery silk and is particularly visible in September and October. The males will display to each other, but will retreat if they feel threatened. A small spider, it has a dark carapace that is between 1.7 and 2.2 mm long and an abdomen between 1.9 and 3.0 mm long. It has a very dark, nearly black, eye field, although the male has a very thin white line behind the first row of eyes. The legs are generally yellow, apart from the front pair on the male, which are brown, longer and stouter and used for stridulation. The male abdomen is black with a pattern of white spots. The female abdomen is very dark brown, nearly black at the front and yellow to the rear. Both have a distinctive iridescent patch at the back of the abdomen that is recalled in the name of the species, which is a Latin word that can be translated "brilliant". It is this iridescent patch that helps to distinguish the species, although a study of the copulatory organs is needed to confirm its identity. The spider was first described in 2008 by Wanda Wesołowska and Meg Cumming. Originally allocated to the genus Pseudicius, it was moved to its current name by Jerzy Prószyński in 2016.
Evarcha arabica is a species of jumping spider in the genus Evarcha that lives in Yemen. The species was first described in 2007 by Wanda Wesołowska and Antonius van Harten. The spider is small, with a carapace that measures between 2.1 and 2.7 mm long and an abdomen that is between 1.8 and 3.2 mm long. The female is generally larger and lighter than the male. The spider's eye field is darker. The top of the male abdomen is blackish-brown with a pattern of white dots and a large yellowish-orange belt. The top of the female abdomen has similar white dots but is mainly yellow with small darker dots. The male's legs are brown and yellow while the female's are orange to yellow. It has distinctive copulatory organs. The female has accessory glands near the copulatory openings and simple bean-like spermathecae. The male has a thin embolus and a tibial apophysis that has a forked tip.
Arctosa perita, also known as the sand bear spider, is a species of wolf spider in the family Lycosidae. They are native to Europe, North Africa, Turkey, the Caucasus, and Russia, however they have also been introduced into Canada. They live on dry, sandy soils or coastal dunes, where they create their burrows.
Nesticus cellulanus, also known as the cavity spider or comb-footed cellar spider, is a species of scaffold web spider. It is found throughout Europe and Turkey, and has been introduced to North America.

The spider has a generally yellow to light brown carapace and a yellowish abdomen, but the female specimens have patterns that can include black, reddish-orange and reddish patches. All the spiders have light yellow spinnerets. The front pair of legs are longer than the others and have brown spines. The spider has unique copulatory organs, with the male having a clump of long dense hairs around its small projection on the palpal tibia, called a tibial apophysis, and the female having sclerotized hoods around the copulatory openings on its epigyne.
