Geographic area: Europe, North Africa, temperate Asia. |
Spiders of the Evarcha genus show a large cephalothorax and strong fore legs. Males Evarcha arcuata are almost black. There are horizontal rows of long white hairs around the eyes, hanging down on the chelicerae. The eyes are sometimes circled by an orange area. The legs are black with brown metatarsi. Evarcha falcata has shorter white hairs on the face. Its abdomen is circled with white. Evarcha jucunda has a cephalothorax circled with white, white tibias and white patches on the pedipalps. Evarcha laetabunda is a paler colour on the upper side of the cephalothorax. Females are browner in colour and much more difficult to tell apart. They show a thin black median line on the front part of the abdomen and oblique lateral black patches at the back. |

During a bike tour, looking for butterflies, I have suddenly stopped when I view a new species. After the photo session, coming back to my bike laid down among high grasses, I saw this small spider standing on one bike's tyre. I took this opportunity to shoot some close up pictures and then add a new species to my collection. |

I have observed this male Evarcha arcuata among nettles. I think that one parasitic acari is attached under its abdomen. |

With patience I have been able to shoot a rear view. Females are very different from males. |

I have approached this old wooden ruler close to the spider to be able to evaluate its size. Intrigued, it jumped on it. The camera being ready and manually set on the shortest focus distance, I have moved the spider towards the lenses to get a sharp view and then I shot the picture. |

I like this picture. You can see my silhouette in the eyes of the spider. The beautiful green colour is got by the reflection of the close shrubs. |
