Description:

Male jumping spider, body length 6mm. Males of this species have two forms: the first, has a black body, pale yellowish legs and three small tufts of black hair on the cephalothorax; the second form (as in this photo) has a grayish body with red, white, and black markings. The female resembles this male form.

This guy was found on the side of my house but they are found all over hunting for food. No waiting on a web for jumping spiders.

@Sharon---great spotting! I had no idea we had such beautiful spiders in Michigan. I am really beginning to look forward to seeing them in my garden this spring!

@ Sharon , i am truly impressed with your very mature and adult like answer..
Your points are logical and you come out as an adult who knows what they are doing. The main reason I do not feel very bad for the spider is that it has experienced sub zero temperatures and maybe it can take it.
i am a scientist too. i have dissected frogs and cockroaches and earthworms etc etc,but in a scientific setting only and because my curriculum required me too.
However on a day too day basis , I do not go about cutting open every critter I see. Nor would a surgeon go around with a knife. So in my view point certain
procedures should be conducted in a scientific setting.
We have the most beautiful collection of spiders in this forum . i have not once read so far that spiders have been frozen for photographing.
i am really happy that you took your concerns up to the Noah team ,because there is where i would have directed you anyways.
i want to clarify that Every word that I wrote to you was cut and paste and i also included the link.
When somebody sent me the link, I did not think that they were "childish" "Bossy' and " Rude"
i feel that i had the maturity to understand the deep message there in. After joining project Noah , I have really learnt to appreciate critters like spiders and Dragon flies and praying Mantis etc. i treat all of them as a special gift .
Welcome to Project Noah !!
We look forward to more spottings from you!
Thank you for the very thoughtful reply.!

Emma,
I appreciate your concern for the animal and I want you to know that I would never purposely hurt one.
On the other hand, your treatment of the human animal leaves a lot to be desired. I don't appreciate your coming on here and scolding me as if I was your child. You could have researched first and then politely questioned me about my methodology. You could also have stated your concerns in a polite manner as if you were an adult talking to another adult. You have the right to disagree with my methodology and say that you were worried about the safety of the animal but I'm new here and jumping right in and telling me what I am not supposed to do is bossy, childish and rude. My feelings are hurt very easily so try getting to know someone before you say that they are "an unfeeling and selfish individual" and try having a conversation with someone and not just snap out commands.
Having said that, I was concerned that some of my "clinical" photos were not appropriate for this particular site, I also post on an entomological site and these may be more appropriate for that setting, but thought that I would give it a try. If the owners of the site want me to remove them for that reason I will do so with no hard feelings and only post my photos taken in a natural setting. I don't think it is your call though.
As far as stress is concerned, I gently get the critter to climb into a small container, being very careful not to hurt it and trying very hard not to stress it.
As far as hurting the spider by putting it in the refrigerator, I live in Michigan and we get temperatures well below freezing, so chilling invertebrates happens in nature. Insects are cold-blooded, which means that their body temperature rises and falls with the outside temperature. Insects that don't migrate enter a dormant stage during winter conditions and they produce special "anti-freeze" chemicals to stop themselves from freezing. These chemicals are called polyhydroxy alcohols and they work with other components (thermal hysteresis proteins) to prevent ice forming. The "anti-freeze" chemicals are found in both freeze tolerant and freeze intolerant invertebrates. The refrigerator is much warmer than our winter freeze and the spider is not hurt. It does slow down with the decrease in temperature but warms up quickly. The chill also helps so that they don't stress out. One little thing, nowhere does it state that "you are not to touch the wild life".
I will send a message to the ones running the program and ask if they would like me to remove the photos. It may well be that they ask me to remove them but I don't think they will say I am unfeeling or selfish. I have no problem removing them if they feel they are inappropriate for what they are trying to do with Project Noah. You should message them with your concerns, also, as should anyone that has problems with it.
You are always free to express your concerns to the appropriate people and let them handle things. I kindly ask that you keep your complaints out of the comment section for my photos, in other words, if you don't have something good to say don't say anything at all.
Thank you,
Sharon

According to the rules of wild life photography you are not supposed to touch the wild life while photographing.
". Never cause stress to the subjects for the sake of a picture."
"It isn’t right to pursue or corner an animal to the point where this pressure will cause stress. This is unprofessional and evidence of an unfeeling, selfish individual"

Haha, so THAT's how you get a jumping spider to calm down. Spotted a fantastic one recently, but every time I got close up for a macro the critter would insist on jumping on the camera... Result: not a single decent photo :-(

Very good photos...great spotting! My compliments, Sharon!
Is the first time when I know that insects can be refrigerated and then photographed :)

I find jumping spiders fascinating & there does seem to be a lot of variation within the same species. They aren't the easiest subjects to photograph though! :)

Thanks so much, Karen. Can you believe this is the same species as the first one I posted :)
