The Napoleon spider

Meet the Napoleon spider, named so because the black spots on this spider’s back resemble the famous French emperor Napoleon. In dutch this spider is called ‘blinkende krabspin’.

I encountered this little fellow at Massembre, a small town in the Ardennes Forest in the Southern part of Belgium. There was a giant meadow of blossoming flowers, and on one of those, a cornflower, it sat. It’s the only one of its kind I’ve ever seen.

Some information about it: the male is not quite as big as the female, only 3 – 4 mm long. A female can be 8 mm long. This makes me think this is a female. According to Wikipedia, it likes grass lands, close to a forest, and high vegetation.

About colours, mature males have a black abdomen with two white marks. In mature females, the background colour of the abdomen can be red, yellow or white. (Source:

As is common to all crab spiders, they are hunters of insects and catch these with their front legs. They don’t make a web.
