I found these on a lilypad.

Moved from Unidentified Immature Stages.

These are tabanid eggs (horse fly or deer fly)--as noted below, not related to the horse bot flies (Oestridae) that lay eggs on horses and develop as larvae under their skin. And to clarify, John had moved the photo from the general fly section to the section for unidentified fly immature stages--he was not questioning whether they were fly eggs. An auto-comment like this is generated any time someone moves a photo on BugGuide. To see where the photo was moved to, look at the string of hyperlinks above the photo.

I agree. These may not be fly eggs. I think we still need an ID.

i think their egg masses are shaped this way

I grew up swatting horse flies off the cows in the milking parlor. I am uncertain about the way it is done but I had the impression the flies, as the bit, deposited an egg under the cow's skin.

Different flies
Horse flies (Tabanidae) don't lay eggs on skin. Some blow flies (Calliphoridae) and bot flies (Oestridae) do.

Later a swelling formed on the skin and eventually a larvae emerged. We used to squeeze them out and step on them.
