Eggs?

Eggs?
Roseville, Placer County, California, USA
April 9, 2012
Size: about 0.2 mm?
Yesterday, I placed this springtail:

and seven others like in a container with a mix of plaster of Paris and activated charcoal. Today I found these. Could they be eggs from the springtails?

This could be...
a cluster of eggs, indeed. At least one egg shows the characteristic 'polar cap' of Collembola eggs. More caps should become visible when the embryos develop further.
See http://www.collembola.org/publicat/egg.htm

can i inquire
as to why the plaster of paris and charcoal? is that food or is it just a house for them and feed them yeast? obviously i know nothing please enlighten me
the eggs must be springtail eggs unless they were allready in there.

 
A standard method for culturing springtails
involves keeping them in containers with a mixture of 9/10 plaster of paris (to retain moisture) and 1/10 activated charcoal (to absorb wastes), along with a few grains of baker's yeast for food. See here: http://www.collembola.org/publicat/magda.htm. I can't see where else the eggs could have come from either, but I'm trying to be "cautious" like a real scientist. :)
