Thomisus onustus

Crab spiders make up the Arachnidae family Thomisidae. They are also commonly called "flower spiders" because they are most often found on flowers, lying in ambush for prey. Crab spiders do not build webs to trap prey, but are active hunters much like the jumping spiders (Salticidae).

They are called crab spiders because of their first two pairs of legs, which are held out to the side giving them (with their flattened, angular bodies) a crab-like appearance. Also, like crabs, these spiders move sideways and backwards more easily than forwards.

The spider family Aphantochilidae was incorporated into the Thomisidae in the late 1980s. Aphantochilus species mimic Cephalotes ants, on which they prey.

The spiders of Thomisidae are not known to be harmful to humans. Spiders of an unrelated genus, Sicarius, also resemble crabs (and are sometimes referred to as "crab spiders"). Sicarius spiders, close cousins to the recluse spiders, are highly venemous.

good lighting and sharpness keep the shot tidy and make the spider prominent

Hola Lucas
Me gusta mucho tu foto, la araña le da un toque especial, pero incluso sin esa araña es una foto muy buena, me gustan mucho esos blancos y como te quedaron.
Un saludo
Jorge

Hola Lucas, buena composición, la araña parece que está entre nubes, muy correctas la tonalidades blancas, con sombras casi mulas, enhorabuena. Un saludo

What a beautiful color - the thumbnail didn't show the spider very well, so I thought upon clicking I was going to look at a nice flower shot. What a cute little surprise!

Thank you for the useful note and beautiful picture.
