Ogcodes Doddi
''Ogcodes'' is a cosmopolitan genus of small-headed flies in the family Acroceridae. About 90 species have been described for the genus. It is the most common and speciose genus in its family. These flies are endoparasitoids of ground-dwelling entelegyne spiders. Characteristics Flies in this genus can be distinguished from other genera in the family Acroceridae by the following combination of characteristics: * Antennae positioned on the ventral surface of the head, slightly above the mouth *Tibiae lacking apical spurs *Eyes always holoptic *Short, rod-like antennal flagellum *Mouthparts hidden by a membrane *Reduced wing venation Adult ''Ogcodes'' are small to medium in size, with rounded heads and abdomens. They are often brown or black in color, with a pale horizontal band at the posterior edge of each abdominal tergite. Life History Soon after mating, females lay their eggs around dead twigs. These eggs are brown or black in color, and usually under 0.35 millimeters in le ...

Wolf Spider
Wolf spiders are members of the family Lycosidae (), named for their robust and agile hunting skills and excellent eyesight. They live mostly in solitude, hunt alone, and usually do not spin webs. Some are opportunistic hunters, pouncing upon prey as they find it or chasing it over short distances; others wait for passing prey in or near the mouth of a burrow. Wolf spiders resemble nursery web spiders (family Pisauridae), but wolf spiders carry their egg sacs by attaching them to their spinnerets, while the Pisauridae carry their egg sacs with their chelicerae and pedipalps. Two of the wolf spider's eight eyes are large and prominent; this distinguishes them from nursery web spiders, whose eyes are all of roughly equal size. This can also help distinguish them from the similar-looking grass spiders. Description The many genera of wolf spiders range in body size (legs not included) from less than . They have eight eyes arranged in three rows. The bottom row consists of fou ...

Jumping Spider
Jumping spiders are a group of spiders that constitute the family (biology), family Salticidae. , this family contained over 600 species description, described genus, genera and over 6,000 described species, making it the largest family of spiderscomprising 13% of spider species. Jumping spiders have some of the best visual perception, vision among arthropods — being capable of stereoptic color vision — and use sight in courtship, hunting, and navigation. Although they normally move unobtrusively and fairly slowly, most species are capable of very agile jumps, notably when hunting, but sometimes in response to sudden threats or crossing long gaps. Both their book lungs and Invertebrate trachea, tracheal system are well-developed, and they use both systems (bimodal breathing). Jumping spiders are generally recognized by their eye pattern. All jumping spiders have four pairs of eyes, with the Anatomical terms of location, anterior median pair (the two front middle eyes) being pa ...

Thomisidae
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. Description Members of this family of spiders do not spin webs, and are ambush predators. The two front legs are usually longer and more robust than the rest of the legs. The back two legs are smaller, and are usually covered in a series of strong spines. They have dull colorations such as brown, grey, or very bright green, pink, white or yellow. They gain their name from the shape of their body, and they usually move sideways or backwards. These spiders are quite easy to identify and can very rarely be confused with Sparassidae family, though the crab spiders are usually smaller. Etymology Spiders in this family are called "crab spiders" due to their resemblance to cr ...

Philodromidae
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 (then known as subfamily Philodrominae within Thomisidae). It contains over 500 species in thirty genera. The most common genus is '' Philodromus'' which is widespread, similar to ''Ebo''. Other common genera include the elongate grass-dwelling '' Tibellus'' and the widespread '' Thanatus'', which includes the house crab spider that commonly captures flies on and in buildings. Description Philodromids have a crab-like shape due to the first two pairs of legs being oriented sideways (laterigrade). This is superficially similar to the "true" crab spiders (Thomisidae), such as ''Misumena vatia,'' but these families are not as closely related as previously thought. Unlike crab spiders, the legs are generally similar in size, though the second leg pair may be significantly longer than the first pair. This is most ...

Ground Spider
Ground spiders comprise Gnaphosidae, the seventh largest spider family with over 2,000 described species in over 100 genera distributed worldwide. There are 105 species known to central Europe, and common genera include '' Gnaphosa'', '' Drassodes'', '' Micaria'', '' Cesonia'', '' Zelotes'' and many others. They are closely related to Clubionidae. At present, no ground spiders are known to be seriously venomous to humans. Description Generally, ground spiders are characterized by having barrel-shaped anterior spinnerets that are one spinneret diameter apart. The main exception to this rule is found in the ant-mimicking genus ''Micaria''. Another characteristic is an indentation in the endites (paired mouthparts anterior and lateral to the labium, or lip). All ground spiders lack a prey-capture web and generally run prey down on the surface. They hunt at night and spend the day in a silken retreat. The genitalia are diverse and are a good model for studying the evolution of genit ...

Sac Spider
The sac spiders of the family Clubionidae are nocturnal, sac-building hunting spiders with a near-worldwide distribution. Their sacs, silken retreats in which they hide during the day, may be made in a variety of places, including between folded leaves or grass blades, under bark and below rocks or other ground litter. Although formerly a much larger catch-all taxon, in its current definition the family contains less than 700 described species across 18 genera, of which '' Clubiona'' is by far most species-rich, with 528 accepted species . Taxonomy The Clubionidae have a complex taxonomic history. Historically, the family was a large catch-all taxon for a variety of spiders that shared the following morphological and behavioral similarities: having eight eyes arranged in two rows; having conical anterior spinnerets that touched; and being nocturnal wandering predators that build "sacs" to retreat to during the day. A large number of genera have been transferred from Clubionid ...

Anyphaenidae
Anyphaenidae is a family of araneomorph spiders, sometimes called anyphaenid sac spiders or ghost spiders. They are distinguished from the sac spiders of the family Clubionidae and other spiders by having the abdominal spiracle placed one third to one half of the way anterior to the spinnerets toward the epigastric furrow on the underside of the abdomen. In most spiders the spiracle is just anterior to the spinnerets. Like clubionids, anyphaenids have conical anterior spinnerets and are wandering predators that build silken retreats, or sacs, usually on plant terminals, between leaves, under bark or under rocks. There are more than 600 species in over 50 genera worldwide. The family is widespread and includes such common genera as '' Anyphaena'' (worldwide except tropical Africa and Asia) and ''Hibana'' (New World). Only one species ('' A. accentuata'') occurs in northwestern Europe. Species in the latter genus are important predators in several agricultural Agric ...

Lynx Spider
Lynx spiders (Oxyopidae) is a family of araneomorph spiders first described by Tamerlan Thorell in 1870. Most species make little use of webs, instead spending their lives as hunting spiders on plants. Many species frequent flowers in particular, ambushing pollinators, much as crab spiders do. They tend to tolerate members of their own species more than most spiders do, and at least one species has been identified as exhibiting social behaviour. Description There are several genera of Oxyopidae: Oxyopes, Peucetia, Hamataliwa, Hamadruas, Hostus, Pseudohostus, Schaenicoscelis, Tapinillus, and Tapponia. Most spiders in the Oxyopidae family have large spiny bristles on their legs and in many species the bristles form almost a basket-like structure that may assist in confining the prey that they grasp, and protect the spider from its struggles. Most ''Oxyopes'' and ''Hamataliwa'' species are small to medium in size. Lynx spiders, in spite of being largely ambush hunters, ar ...
