Pseudoscorpion (Lasiochernes cretonatus) II

So, I was rather upset after my encounter with the pseudoscorpion, here: http://procezzed.blogspot.com/2012/03/pseudoscorpion.html, because the photographs were so terrible, detail was almost impossible to discern. So, I took a magnifying glass, a pad of paper, and some colored pencils, and I sketched out what the creature I found looked like. This is a freehand based on observations made of the little arachnid. I hope it can clear up some questions about what it looked like in detail. I should probably invest in a better camera... however that's somewhat out of the question with my limited funds right now. Enjoy my drawing: 
A description taken from National Audubon Society Field Guide to North American Insects & Spiders
"Pseudoscorpions are small, flat arachnids, usually less than 1/4" (5 mm) long. Like true scorpions, they have enlarged, pincerlike pedipalps, but the short, oval abdomen does not have a tail or stinger. Some species have 2-4 simple eyes; others do not have eyes. Many species have poison glands in the pedipalps, which are used to subdue insect prey and small invertebrates. Pseudoscorpions also have silk glands, but unlike spiders, which have them at the tip of the abdomen, the duct openings are located on the jaws, or chelicerae. They use this silk to spin cocoons, in which they overwinter and molt. The male in one species produces another kind of silk from the rectum, spinning threads that direct the female to the stalked sperm packet. In most species, the female's brood pouch remains attached to the female's abdomen, and hatchlings stay in the pouch, feeding on a milklike liquid from the female's ovaries. In some species, the female abandons the pouch and the embryos develop unattended. Often young require several years to mature to adults. Some species can live up to 4 years. 
Pseudoscorpions are common in many different habitats- at the seashore, in caves, in houses between the pages of books, and in woods among mosses and under loose bark, leaves, and stones. They can maneuver with great ease, moving forward, backward, and sideways. Frequently, they latch onto large insects, especially flies and beetles, and ride them to a new location. There are over 350 North American species, and about 2500 species known worldwide."

Bowl-and-doily spider (Frontinella communis)

3/7/2012
Identifying spiders. Something I sort of cringe at the thought of, however this little guy was the only non-venusta orchard spider I ran into the entire day. So I tried to get some nice photos and figure out what he is! Found him in a small little tangle web between two branches on a crepe myrtle tree. He has a black abdomen but some white markings on the sides. 
I was browsing this website, with the presence of itching and uncomfortable sensations all over me (imagining spiders), and stumbled upon the Bowl-and-doily spiders (Frontinella communis). A quote from the website is that: "These spiders have typically showed up in the branches of small trees. Their webs have two parts, one that is bowl-shaped and another below it that is disk-shaped and looks like a doily. When prey lands on the "doily," the spider leaps down from the "bowl" and attacks it." I really wish I had paid more attention to the shape of the web. All I really noticed was it's tangled appearance. Gonna to a bit more research on it, however. See what I can find. http://bugguide.net/node/view/379115/bgimage
Fairly certain at this point. I'm going to say I'm 86% sure that this spider is Frontinella communis. Once again, no way to prove it but solely based on markings and characteristics.

Pseudoscorpion (Lasiochernes cretonatus)

3/7/2012
sorry the pictures are so blurry/ inadequate. This guy was preeeeetty tiny. 
This little guy was only about 1.5 mm long. I had been out exploring in the backyard taking pictures and I picked a fungi to later get a spore print for only to find back at my house this interesting little creature. Not a massive fan for the creepy crawlies, really only butterflies and moths but this guy, I had to admit, was fascinating. At first, since I had no idea what he could be, I googled pincer spider and scorpion spider. Quickly became disgusted and had the sensation of things crawling all over me after looking at only a few pictures. I proceeded to google insects with pincers and after a bit I stumbled upon the 'pseudoscorpion'. I have not successfully identified it's genus and species but I have also not taken the time to truly do an intense search. I found it necessary to post it to here simply because this little guy REALLY interested me. Sorry the pictures are not as good as they could be my camera is only 16 megapixels and the macro isn't something to brag about. It tends to treat me pretty well, however, when not zoomed in too much. Just thought I'd share this rare little gem, the pseudoscorpion.

Apparently not much is known of them and identification would be very difficult if not impossible. Maybe I can make it to a library sometime this week and they will have a reference book for arachnids.


My post on Project Noah was responded to by the very helpful, Injica. They suggested it could be Lasiochernes cretonatus. It seems to be the correct/ closest to being correct option I've had this entire time. I'm going to go with it. http://www.dochterland.org/pseudosc.htm the first picture on the website is impeccable and incredible quality.

Venusta Orchard Weaver (Leucauge venusta) 2

Today I ran into another Venusta Orchard Weaver (Leucauge venusta). Since in my PREVIOUS POST the pictures weren't completely fabulous, I decided to take some more. This time I took my time to get a good focus, so here they are!

Venusta Orchard Weaver (Leucauge venusta)

2/24/2012
Never been much into bugs, especially not spiders. But I figure maybe if I learn more about them, I might not be so irrationally afraid of them. In my little park excursion I passed a small spider balancing in it's tightly spun web and I decided to take a picture and identify. 
Basically, with only a little bit of digging, I uncovered that it is most likely a Venusta Orchard Weaver, based of comparisions made to pictures and descriptions on this website: http://www.spiderzrule.com/venusta.htm
however, it states that in this species there are several varieties. The one I found is one with red markings on it's underbelly. It's scientific name is Leucauge venusta. 
I put my hand behind it so the camera could get a good focus. AND IT DID!! See the picture below, you can see the hairs on the spider's legs. eerie...
