Moved
Moved from Hypogastrura.

Isotomidae + Ceratophysella + Hypogastrura
It is quite a mix you have here. Blowing up the picture revealed that most of the specimens (greyish ones) are Isotomidae. The whitish-yellowish-pinkish ones are Ceratophysella sp. And the deep purplish or bluish ones are Hypogastrura sp. So Hypogastrura are a minority in this mix.
It is best to move this picture to the family Isotomidae. And provide a link to the 3 other pictures. Also in those the Isotomidae were visible, but then as a minority, while they are now the majorty.

Cropping
This image has a lot of detail, but only you and the editors can see it. Many experts are not editors, and won't see the hidden detail. Please see this article. http://bugguide.net/node/view/170176

 
crop
on my browser (firefox) the BugGuide website allows excellent
enlargement, I guess I have established the context tho

Cropping
I cropped this to show what I meant. Let me know what you think.

 
Cropping
The picture you uploaded is 1876x1156. BugGuide reduces that to 560 on the longest side and that is all that any visitor can see (other than you and editors). If you look up when reading this comment, that is all anyone else can see. They can not click the image to get the full-size image. If you crop out a section of the center NO BIGGER than 560 on ANY side, thus removing the unneeded water, people including experts can see the details of the bugs.

 
looks good
I was about to send the same thing !
(I thought everyone could enlarge the pix)

Ceratophysella sp.
These more pale specimens are more likely Ceratophysella sp. then the deep blue Hypogastrura. Same family though.
