What can these be?

Hi have yellow type eggs in clumps in my greenhouse that are on top of the compost/horse manure mix. What are these?

Regards

 

could be this one...
Entomologia agraria: Cavolaia

 

Can you post a pic, I would have thought too early for butterflies , they could be slug eggs , or vine weevil

 

Slug or snail eggs are either clear or milky coloured and Vine weevil eggs are too small to be seen easily with the naked eye.

 

You don't own a Bantam by any chance ?:WINK1:

 

will try to get a pic up i think it is something that was in the horse manure as i added the manure about 6 weeks ago.

 

Sounds like slug eggs to me ! We have big orange horrendous things sometimes as big as 4 inches plus really really gross!!!

 

Pictures

Here are some pictures i took this morning

 

id go with choppers reply,look like slug eggs to me

 

ok would they have come in the horse manure?

 

slug eggs?

if these are slug eggs then my greenhouse is full of them, all stuck in clubs on the horse manure.What can i do to kill them without harming plants that i have allready planted?

 

Looks more like a fungal growth to me.

 

I agree with Dai ,the first picture struck me as a fungal growth ,could not really see the other two very clear...

 

Marley will id it if it`s a fungus.

 

I'd say fungal as well.
If its on manure, I doubt its a problem.

Just natures way of breaking the stuff down.
