Metazygia zilloides is a species of orb weaver in the spider family Araneidae. It is found in the United States and a range from the Caribbean Sea to Honduras. [1] [2] [3] [4]
Huntsman spiders, members of the family Sparassidae, catch their prey by hunting rather than in webs. They are also called giant crab spiders because of their size and appearance. Larger species sometimes are referred to as wood spiders, because of their preference for woody places. In southern Africa the genus Palystes are known as rain spiders or lizard-eating spiders. Commonly, they are confused with baboon spiders from the Mygalomorphae infraorder, which are not closely related.
The Araneomorphae are an infraorder of spiders. They are distinguishable by chelicerae (fangs) that point diagonally forward and cross in a pinching action, in contrast to the Mygalomorphae, where they point straight down. Araneomorphs comprise the vast majority of living spiders.
The Pholcidae are a family of araneomorph spiders. The family contains more than 1,800 individual species of pholcids, including those commonly known as cellar spider, daddy long-legs spider, carpenter spider, daddy long-legger, vibrating spider, gyrating spider, long daddy, skull spider, and angel spider. The family, first described by Carl Ludwig Koch in 1850, is divided into 94 genera.
Crevice weaver spiders (Filistatidae) comprise cribellate spiders with features that have been regarded as "primitive" for araneomorph spiders. They are weavers of funnel or tube webs. The family contains 18 genera and more than 120 described species worldwide.
Hexathelidae is a family of mygalomorph spiders. It is one of a number of families and genera of spiders known as tunnelweb or funnel-web spiders. In 2018, the family was substantially reduced in size by genera being moved to three separate families: Atracidae, Macrothelidae and Porrhothelidae.
Velvet spiders are a small group of spiders almost entirely limited to the Old World, with the exception of one species known from Brazil. In Europe, some are commonly called the ladybird spiders.
Psechridae is a family of araneomorph spiders with about 70 species in two genera. These are among the biggest cribellate spiders with body lengths up to 2 centimetres (0.79 in) and funnel webs more than 1 metre in diameter.

Allocyclosa is a genus of orb weaver spiders that contains only one species, Allocyclosa bifurca. It was first described in 1887 by McCook under the name Cyrtophora bifurca, and was transferred to its own genus in 1999. It is the only Cyclosa species north of Mexico to have a forked rear tip of the abdomen hence the name bifurca, Latin for "two-pronged". The forked tip of the abdomen, bearing two humps shaped like the letter M, is a defining feature in both males and females, though it is similar to features present in certain Cyrtophora species. Both sexes are a grey-green color, though only females have an area of red on their underside between the epigynum and the spinnerets. Females are much larger than males, ranging from five to nine millimeters, while males range from two to three millimeters. Males appear to be very uncommon, but they are probably often overlooked by collectors due to their small size. In a 1977 study by Levi, only two of the nearly 350 specimens that were positively identified as Cyrtophora bifurca were males. This is a very unusual distribution; a second, less likely explanation that has been proposed is that females of the species, which have less prominent genitalia compared with those of other members of the orb-weaver family, may be parthenogenic, are able to reproduce without the help of males. Like most other members of Araneidae, these spiders build orb webs, six to eight inches in diameter, but employ an unusual form of protective mimicry. Females often sit in the middle of a vertical row of web decoration that include egg sacs and wrapped prey. Because the spider and the egg sacs have a similar color and shape, it is difficult to distinguish the egg sacs from the spider itself.
Metazygia is a genus of orb-weaver spiders first described by F. O. Pickard-Cambridge in 1904. They physically resemble members of Nuctenea, but they do not have fine setae on the carapace.
Clubiona kastoni, the kaston sac spider, is a species of sac spider in the family Clubionidae. It is found in the United States and Canada.
Habronattus tarsalis is a species of jumping spider in the family Salticidae. It is found in the United States and has been introduced into Hawaii.
Habronattus conjunctus is a species of jumping spider in the family Salticidae. It is found in the United States and Mexico.
Diguetia albolineata is a species of desertshrub spider in the family Diguetidae. It is found in the United States and Mexico.
Acanthepeira stellata, known generally as the starbellied orbweaver or starbellied spider, is a species of orb weaver in the spider family Araneidae. It is found in a range from Canada to Mexico. It is most commonly found along the Eastern and Western coastline of North America.
Philodromus marxi, the metallic crab spider, is a species of running crab spider in the family Philodromidae. It is found in the United States. It is a sexually dimorphic species. The males are smooth with a metallic sheen and the females are bristly white and grey.
Mastophora phrynosoma is a species of orb weaver in the spider family Araneidae. It is found in the United States. Like all known species of the genus Mastophora, adult females are bolas spiders, capturing their prey with one or more sticky drops at the end of a single line of silk rather than in a web. Males and juvenile females capture their prey directly with their legs.
Metazygia wittfeldae is a species of orb weaver in the spider family Araneidae. It is found in a range from the United States to Costa Rica.
Scytodes fusca, the brown spitting spider, is a species of spitting spider in the family Scytodidae. It is found in Central and Southern America, has been introduced into Europe, tropical Africa, Seychelles, Myanmar, China, Japan, and Hawaii.
Phidippus comatus is a species of jumping spider in the family Salticidae. It is found in North America.
