Hi
I was hunting for bugs again yesterday and found this little fellow very near to my house....eeewww! He is a Jumping Spider but a different colour than the one I posted last weekend. This image was taken in kinder light and I had a better shot of his amazing eyes. Hope you like him!

Thanks to members who posted some advice on getting insects sharp front to back. I have been experimenting with the aperture settings and almost got this one right!

Jumping Spiders
Jumping Spiders belong to a large family of spiders which contain very colourful species. They are small to medium size and are easily recognized by their eye patterns. Their front pair of eyes are very large, with another three pair of smaller eyes on thorax, in three rows of 4-2-2. They have very good eyesight and are active during the day. The arrangements of their four pairs of eyes give them virtually 360 degree vision.

Each species in this family have different colourful patterns on their body. When you look at them, they will either hide away on the other side of the leaf or will turn their head and look back at you.

Jumping spiders do not build webs. They make silken retreats between leaves, barks or stones. Their retreats usually have opening at both ends. They hide in their retreats at night and during winter.

The females lay eggs in their retreats in spring and summer. Their number of eggs is relatively fewer than most other spiders. Female spiders will guard their eggs. Usually Jumping Spiders will not hunt too far away from their retreats. Male and female may live together in mating season. This is not common in the spider world.

When Jumping Spiders move or jump, they always leave a safety line of silk, or the drag-line, behind. If the jump misses the spiders can climb back to its original position.

Jumping Spiders hunt on plants during the day. They have complex eyes system and considered to be the best vision among all the animals of their size. The eyes of jumping spiders, especially the largest pair of eyes, are constructed very differently from vertebrate and insect eyes. Each eye has a long eye tube which is attached with a set of muscles, it is capable of precise rotate and move. However, jumping spider's eyes can not adjust the focus. The retinas have a four-layer and tiered arrangement. There is another lens just in front of the retina. This makes the spider's eyes a telephoto lens system. The spider can see sharp image ranging from one body length to infinity. It is also believed the jumping spider can see colours.

They use their excellent vision to track the prey and estimate distance. Then suddenly jump on their prey. They use their third and fourth pair of legs for jumping. They seize prey by front pair of legs.

Hello Sue,
Nice to become neighbour with you. many thanks for your nice critique. I also see a great macro-shot of Salticid species from Australia. They are beautiful spiders as like Thomisidae members. Especially their large compound eyes look very beautiful always. They looks like big mirrors. Great details and sharpness. Nicely composed from nice POV. Thanks for sharing. have a nice weekend

Hi Sue,
you found a great specimen on your Bug Hunt here! Good detail and an excellent PPOV from the front showing us his face and that impressive row of eyes. The DOF is right where it's neeeded here, but you may have got away with an even smaller aperture..
Great stuff, skeep snapping!
