Ladybird spider male

Eresus walckenaeri


Eresus walckenaeri is a species of ladybird spider from the eastern Mediterranean and probably the commonest Eresus species in Greece. Only mature male ladybird spiders have the classic red body with four black spots, while females are velvet black or dark grey. The males do not mature until about 2 1/2 years and only reach a size of 6 to 11 millimeters. Females mature later at 3 to 4 years and grow larger, reaching 8 to 16 millimeters. The pictured male was spotted and photographed in Kassandra peninsula, Chalkidiki Greece.

Your spotting has been nominated for the Spotting of the Week. The winner will be chosen by the Project Noah Rangers based on a combination of factors including: uniqueness of the shot, status of the organism (for example, rare or endangered), quality of the information provided in the habitat and description sections. There is a subjective element, of course; the spotting with the highest number of Ranger votes is chosen. Congratulations on being nominated!

Eresus is one of my favorite spider genera, @Mark! Just because they are so striking beautiful, both males and females!

Dear @Neil Ross, what's interesting about this genus is that their common name describes the males, and not the females...Yet, both genders are lovely!

Dear @Marek Koszorek, I love the females as well, I think they are fascinating, and they are exceptional mothers!

Dear @Saturniidae27, you are correct, they do look like red velvet buttons with legs!

Dear @ornithoptera80, fortunately the species is very common in Greece, along with at least 3 more species of the Eresus genus. Males are bright red with black spots and white stripes on their legs, and they are super cute and harmless! In the last pic you may see the actual size!

Nice spotting, Despina. It's a pretty spider, and certainly true to it's name.
