Hi whilst doing some high magnification images of a mayfly specimen I noticed what appear to be eggs attached to the head. I'm curious if anyone could offer a suggestion as to what they are or even if they are eggs. I understand there are stonefly parasites is this also true of mayflies?

I'm not sure what those are base on the picture, but I often see mystery things attached to specimens. Sometimes, these are a fungus, and rarely they are aquatic mites. A frequent thing I see is little pale pouches of "goo" that appear as an artifact of the fixation and preservation process.
These could be eggs of some kind, but what kind I do not know. Might even be eggs from another mayfly. Many of these adhere to whatever happens to be on the stream bottom, even if it is another living thing.
