The Strange Spiny Orb Weaver Spider, or what is called the ‘Crab Spider’ is an indeed remarkable animal. Here are a few things you should know about it.
- What Does It Look Like
Crab spiders have their name and nickname because of the spines that project from their abdomen, which makes their body to really look like a crab. This species is a very colourful and easy-to-recognize spider. They have white abdomen which also contains several black spots and their spines have a red colour that extend from their abdomens’ edges. The rest of their body is black. When searching at the areas where this spider is distributed, there have been reported that some of these crab spiders have their abdomen yellow instead of white, with their spines being black. Their size is not large at all. Females are almost 1 cm long. The males are even smaller and have different colouring and smaller spines.
- Habitat, Diet And Behaviour
Typically, Crab spiders tend to have habitats in woodland edges and on various bushes and gardens. In addition, they tend to plant some nurseries for their protection, which are commonly found in citrus trees. Crab spiders frequently spin their webs in bushes, trees, and windows and doors’ corners. This spider does not tend to enter homes, but they are sometimes unintentionally enter inside houses when they enter potted plants or are placed on some garden furniture. Their diet consists of several insects that are captured using their web. The Insects they prefer are beetles, moths and mosquitoes. The Crab spiders’ prey is captured in the web and then the spiders bite and paralyze them, consuming their bodies liquids in the way that most of the other spiders do. What is interesting however is that their web has silk tufts which are built by the female spiders. This is done is order to make the webs more visible to birds and thus reduce the possibility of them flying onto them and hence destroy it.
Normally, Crab Spiders can for only one year. In most of the areas they live, several females are found all year around, but most of them are found in the winter. Males are usually found only in October and November.
In order to reproduce themselves, female crab spiders produce egg sacs during summertime or in the winter. These sacs typical contain one to two hundred eggs. Then, the females attach their eggs under several leaves, which use them to wrap them with extra web and they subsequently die. The eggs require approximately two weeks to hatch.

Crab spiders are usually found across the world, but they are mostly found in USA, where they live in California and Florida. These spiders can bite, but they are not reported to be aggressive. Their bite is not considered medically important, as it is not life-threatening and most likely they will hurt humans if they are touched on their spines.
