| [Note Guidelines] Photographer's Note |
Spiders, unlike insects, have only two body segments instead of three; a fused head and thorax (called a cephalothorax or prosoma) and an abdomen (called the opisthosoma), supported by a hard exoskeleton composed of mainly of chitin. Spiders also have eight legs (insects have six), no antennae, and their eyes are single lenses rather than compound eyes. Additionally spiders have pedipalps (or just palps), which are two appendages next to their mouths that aid in manipulating food.
Many spiders hunt by building webs to trap insects. These webs are made of spider silk, a thin, strong protein strand extruded by the spider from spinnerets on the end of the abdomen. All spiders produce silk, although not all use it to spin elaborate traps. Silk can be used to aid in climbing, forming smooth walls for burrows, cocooning prey, and for many other applications.
Despite their generally broad prey ranges spiders are one of the most important links in the regulation of the populations of insects. Every day on a meadow they devour over 10 g/m² of insects and other arthropods.
Over 37,000 species of spiders have been identified but, because of their great ability for hiding, it is believed there are nearer 200,000 species. Almost all species are venomous, but only 30 species are known to be deadly dangerous.

Very nice. Great detail - the colors are very nice and rich as well. Good job. These are the kinds of shots that inspire me to go out and get a macro lens. TFS

Bonjour Christos, superbe photo de l'araignée Argiope bruennnichi femelle (argiope frelon en Français). L'on apercoit vers le bas une partie de toile brillante, c'est ce qui est appelé le stabilimentum vertical. Cela sert, grace aux reflets de la lumiére, a attirer les insectes. Trés bon piqué et belles couleurs. TFS Didier.
