Jumping Spiders  - Platycryptus

Typical jumping spiders in the genus Platycryptus are gray with black markings. The genus Platycryptus was erected by David E. Hill in 1979 and is a combination of Greek words for “broad, flat” and “hidden.” The combined term refers to how cryptic the spiders are, and how their body shape allows them to hide in crevices (Hill 1979). The specific epithet, undatus, is Latin for “wavy” and was chosen by Charles De Geer in 1778 to describe the scalloped and wavy pattern on the abdomen of this spider. Platycryptus undatus is a common jumping spider which ranges from the Eastern States and adjacent Canada, to Texas and Wisconsin. Females of this species are between 10 and 13 mm in body length, and males range from 8.5 to 9.5 mm. Like some other species of jumping spider, this species appears to exhibit curiosity towards humans who come into its visual field (jumping spiders all have very good vision.) It favours vertical surfaces such as fences, walls, etc. and because of its habits it is easily seen. It does not frantically flee humans and may be gently "herded" onto a hand, where it may make a thorough exploration and even jump from finger to finger. These spiders are not at all inclined to bite, but even though they are rather small they can deliver a defensive bite if they are pinched or squeezed. Eggs are laid and hatch during the summer, and adults and other stages stay over winter in their individual silken shelters. Although the shelters are built separately and keep the spiders out of direct contact with each other,  as many as fifty of them may crowd their shelters for hibernation together so tightly that they form a continuous blanket under the loose bark of a standing tree. The bodies of these spiders are rather compressed in the vertical direction, which allows them to hide themselves under the loosened bark of trees and in other tight places. They have a prominent pattern on their abdomens which may make them more difficult to distinguish on mottled surfaces. They are tan in colour. The genus Platycryptus was erected by David E. Hill in 1979 and is a combination of Greek words for “broad, flat” and “hidden.” The combined term refers to how cryptic the spiders are, and how their body shape allows them to hide in crevices (Hill 1979).

JUMPING SPIDERS

Jumping spiders (Salticidae) are the personalities of the spider world. Though generally small in size (up to 12 mm body length), their large eyes, prodigious jumping ability, often brilliant colours and cocky, inquisitive activity make them very appealing. Many are daylight hunters, using their excellent vision to track, stalk and calculate distance, before suddenly leaping on their prey, propelled by their strong back legs. Males are often more strikingly coloured, patterned or adorned with leg or body hair tufts than are females. They use these adornments to impress the females during often elaborate courtship displays. Information - Australian Museum

This spider was in a home in central Wisconsin near Lodi. Any information would be appreciated. A family member was recently bitten by some type of spider or insect and it has caused swollen glands, fever and lethargy. Thank you Kay

Hi, Glen! I wanted to share some pics with you that I’ve captured of spiders on the cars at my work place. I don’t always know what kind of spider they are, but it never matters. They’re all so intriguing. I’ve also decided to send a couple of one that was hanging out with me at my mom’s place. The little guy was thirsty! Jen

I live in Vancouver, Canada and took the attached picture of a spider on a wall in the house. The picture is not great quality, but hopefully you can identify it for me. I believe the spider was about 1/2".

Thank-you!

Love the site. First I thought this was a grass spider, but then I got a little closer and now I'm not so sure. Any thoughts? He's just been motoring around my apartment in Michigan for the past couple of days. He's quite the active little guy. I recently found this spider in my backyard and wondered what type of spider it might be. Can you help?

Good Afternoon, I have a picture attached regarding a spider that I found at my front door. Any help in telling me what type of spider it is? (I thought it may be a grass spider) I have a few other spiders around the home that I will eventually send pictures of as well. I live in PA, and so our farmland brings in lots of different insects, birds and animals.... Thanks for helping, Heather

Hello! Sorry I know I send in pictures a lot, but I'm just so curious. This was a little guy.. Probably about the size of a dime, legs and body. I'm usually pretty good and figuring out what they are and then sending in a pic for you to double check but I can't figure this little guy out!

This spider was found hanging around a golf course in Muncie, Indiana. I cannot find a match on the internet but came cross your website. You seem like you know your stuff. Any idea? It's a real beauty, but so is my daughter, and she is ready to pack and move away for fear she will encounter another. Thanks! Alice
