A global citizen science platform to discover, share and identify wildlife
Nature School For Teachers - Fall 2020 Launch!
No worries. This is one of those bugs that is a problem to identify conclusively. A continuous source of frustration.Dave
Thank you al for the links and comments,sorry little late replay,back at work on board for several weeks now.Cheers.
Fabulous looking jumper ,great photograph.
I couldn't find anything in the Wiki link to confirm anything and the other link is just images from Flickr that anyone can post. Just my opinion, but this is not conclusive.I do suspect that all of yours, mine and on this post, are all umbratica, but I crave the opinion of an expert, something that I have never found.Dave
So colorful spider!!
For male of C. Umbratica, all information for identification can be found in wikipedia - http://en.wikipedia.org/wiki/Cosmophasis.... My spotting for the male one matching C. Umbratica characteristic...The female of C. Umbratica is harder to ID because of a variation in the abdomen. But, i assume they are a pair of a species, because they are on the same tree (and in nearby leaf). Check this link for more pictures - http://www.jumping-spiders.com/php/tax_d... (maybe not all ID are correct)
Lanzz - great images. BUT, how confident are you that the PA20 link is an expert opinion. Like Bayucca, I am not confident enough to go to species level for any of these spiders. It is a super set of arachnid images and I hope it is an expert behind them.I hope to find a pair actually mating one day. So far, in two years, no success. Both spiders being on the same tree or bush, I don't think is good enough for such an assumption. A fair probability yes, but not definitive.Dave
This spider is beautiful... Folicallychalled, you also have many spotting of the spider from this genus... All of them are beautiful, and i hope you can find the ID for these spider...I don't think this spider is C. Umbratica... Here are my spotting of C. Umbratica, that i found on the same tree (so, we might safely assume they are a pair of a species).Male - http://www.projectnoah.org/spottings/133...Female - http://www.projectnoah.org/spottings/143...
Wonderful set of Cosmophasis, Dave!! It really looks to be a tricky genus with a tremendous variability.http://potokito-myshot.blogspot.ch/2012/...I guess you know this site as well:http://salticidae.org/salticid/catalog/c...http://salticidae.org/salticid/diagnost/...
Here are links to mine.Males:http://www.projectnoah.org/spottings/204...http://www.projectnoah.org/spottings/204...http://www.projectnoah.org/spottings/195...http://www.projectnoah.org/spottings/199...Females:http://www.projectnoah.org/spottings/204...http://www.projectnoah.org/spottings/204...http://www.projectnoah.org/spottings/197...http://www.projectnoah.org/spottings/193...http://www.projectnoah.org/spottings/204...I actually photographed a small female this morning:http://www.blipfoto.com/entry/3946958Dave
Dave, to be honest, I am glad to have the genus and maybe some features or arguments for going down to species level, but I cannot bother about the sex ;-). In some jumpies it is very easy, but most of the time I am out of the game...In this case, I cannot help more than the genus.
Bayucca - great site. Numbering from the top, I believe the first four are all females, although No3 looks 50/50. The last two are both males. No3 is very confusing, as I can see coloration and pattern features of both sexes.Differences in patternation can be seen between all the females and none of them match what I have in my collection.DAve
Good link! I am not as experienced with jumping spiders to judge these IDs and the possibilities of variation within the genus and species itself. I still would not dare to call this Umbratica, from that what I see and know (which is not really much)...
My thinking of female Umbratica is only based on pictures #4, (#5) and #7 of this link:http://siamensis.org/node/34567/trackind...But I am not sure if the ID is correct. The only thing I am sure is, that it is a Cosmophasis sp.Do you have pictures of yours?
Here is a link to a very good PDF, showing the mating and the difference between the male and female. It seems as though there are lots of variations in umbratica, or should I say sub-species, as the differences are not random.http://www.google.com/url?sa=t&rct=j...Dave
Bayucca - I have five variations of this arachnid, none of them are a match. I agree, I think this is a female also. I believe the males are more blue. There doesn't seem to be much difference in the pedipalps, which makes sexing these spiders difficult.Dave
Salticidae, Heliophaninae, Cosmophasis sp.http://en.wikipedia.org/wiki/Cosmophasis...http://en.wikipedia.org/wiki/File:Cosmop...http://arachne.org.au/01_cms/details.asp...Close, but not the same:http://www.photoforum.com.au/showthread....)Looking at this link, it might be Cosmophasis umbratica, but looking at other Umbraticas, I am not sure if this ID from Thailand is correct:http://siamensis.org/node/34567/trackind...So, is it really Cosmophasis umbratica, female??http://salticidae.org/salticid/diagnost/...
