What is spider lady bug?

As an AI language model, I could not find any specific information about "spider ladybug." However, there is a common name for a type of beetle known as "spider ladybird" or "ladybug spider." The scientific name of the ladybug spider is Eresus cinnaberinus, and they are found in Europe and Northern Africa. They are known for their striking red and black markings and their ability to mimic the appearance of a ladybug to deter predators. The spider ladybirds are not dangerous to humans and mostly feed on insects, particularly beetles.
