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, are known by this name because of their speed and mode of hunting. 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, and skull spider. The family, first described by Carl Ludwig Koch in 1850, is divided into 94 genera.
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 tail, hence the name bifurca, Latin for "two-forked". The forked 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 transparent green color, though only females have an area of red on their underside between the epigynum and the spinnerets. Females are nearly thirty percent larger than males, ranging from five to nine millimeters, while males range from two to three millimeters. Males are very uncommon. 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 odd distribution, and it has been posed that females of the species, which have less prominent genitalia relative to other members of the orb-weaver family, may be parthenogenic, or able to reproduce without the help of males. Like other members of Araneidae, these spiders create orb webs, six to eight inches in diameter, but apply a unique form of protective mimicry. Females sit in the middle of a vertical row of web decoration, with egg sacs above and wrapped prey below. Because they all have a similar color and shape, it is difficult to discern between the egg sacs, the wrapped prey, and the spider itself.
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.
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.
Lauricius hooki is a species of false wolf spiders & wandering spiders in the family Zoropsidae. It is found in the United States.
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.
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.
Tetragnatha straminea is a species of long-jawed orb weaver in the spider family Tetragnathidae. It is found in the United States, Canada, and Cuba.
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.
Centromerita bicolor is a species of sheetweb spider in the family Linyphiidae. It is found in the United States, Canada, and Europe.
Philodromus imbecillus is a species of running crab spider in the family Philodromidae. It is found in the United States and Canada.
Loxosceles devia, the Texas recluse, is a species of recluse spider in the family Sicariidae. It is found in the United States and Mexico.
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.
