CLOSE UP --The Grass Spider

This is one of my favorate species of spiders. She is related to the crab spiders. Useing a small plastic petree dish, I got some serious close ups on this Tibellus oblongus. They are hard to find since they blend in so well with grass and folage. That flying beetle shot was nice, but spiders still have the most of my interest. This one made it to my outside light last night.

Here you can see the eyes which are actually quite small for a hunting spider. Her main senses can be seen in those hairs on her limbs. They are highly sensitive to vibration.

On the underside we can see her clearning one of her limbs, and clearly we can also see her female reproductive organ, the small black mark on the abdomen, the epigynum.Another shot of her cleaning her limb. Spiders often do this and keep themselves quite clean.

The full underside as best as I could with the setup I had here. It took me couple of hours of shooting to get these shots.

Here she is about 0.5mm above the ruler here but this gives you some idea of her size, she could grow to have a body 10mm long.

Hanging out here, as you can see she's in the plastic dish and just about 0.5mm above the surface here. To take these shots in doors, I used a LED flashlight to see through the SLR viewfinder well.
I tried my best to get through any glare and get the best shots I could of this spider as she was in the dish. She's nearly fully grown but they get a bit larger.

Then I let her go right where I caught her, this is the typical way they sit in wait. They are a sly and very quick species.

The Grass Spider -one of many-NOT BROWN RECLUSE

This is a very common species. Possibly the most common of all spiders in many Northwest places. This is NOT A brown recluse! I was very mad at one site that used a picture of this very common garden spider to sell there products. This spider is VERY common and There are probably well over 100 adults living in any small yard and house with room for a small garden in the backyard. They are shy and not at all related to dangerous species. These spiders can be seen by the dozens making there sheet webs on shrubs--and also can be found in rocks or under them, where I found this female. All spiders are potentially dangerous, do not handle--but please do not kill. These spiders eat 1000s of destructive insects and that can be very well seen if you go into your back yard, garage or basement where these spiders can sometimes be found and examine the remains of there victims. They are major insect predators. Agelenopsis sp. (Agelenidae) There seems to be several varieties of this spider large and small. Another common name for it is the Sheet Web spider as they make sheet webs with a funnel that they hide in. They are very shy--and will run at the slightest bump. I have a lot of pictures of this spider I have yet to post, this one I took recently of an adult female.
