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.
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. It contains over 500 species in thirty genera.
Misumena vatia is a species of crab spider with a holarctic distribution. In North America, it is called the goldenrod crab spider or flower (crab) spider, as it is commonly found hunting in goldenrod sprays and milkweed plants. They are called crab spiders because of their unique ability to walk sideways as well as forwards and backwards. Both males and females of this species progress through several molts before reaching their adult sizes, though females must molt more to reach their larger size. Females can grow up to 10 mm (0.39 in) while males are quite small, reaching 5 mm (0.20 in) at most. Misumena vatia are usually yellow or white or a pattern of these two colors. They may also present with pale green or pink instead of yellow, again, in a pattern with white. They have the ability to change between these colors based on their surroundings through the molting process. They have a complex visual system, with eight eyes, that they rely on for prey capture and for their color-changing abilities. Sometimes, if Misumena vatia consumes colored prey, the spider itself will take on that color.
The genus Oxytate, commonly known as grass crab spiders, comprises a homogenous group of nocturnal crab spiders. The complete mitochondrial genome of the type species O. striatipes was determined in 2014.
Epidius is a genus of crab spiders that was first described by Tamerlan Thorell in 1877. It is a senior synonym of Pothaeus.
Angaeus is a genus of Asian crab spiders first described by Tamerlan Thorell in 1881. It is considered a senior synonym of Paraborboropactus.
Megapyge is a genus of spiders in the family Thomisidae. It was first described in 1947 by Caporiacco. As of 2017, it contains only one species, Megapyge rufa, of Guyana.
Misumessus is a genus of North American and Caribbean crab spiders first described by Nathan Banks in 1904. They look similar to members of Misumena, but are much spinier. It was considered a monotypic genus until 2017, but its taxonomic standing has been debated throughout the 20th century, first as a synonym of Misumenops, then later as its subgenus. It was raised to genus status in 2008, but has still been confused with similar genera, some of which were only known by character descriptions made by Eugène Simon nearly fifty years earlier.
