Egg question
 

Newbie here,

I live in the UK and built a wildlife pond in my back garden about 6 weeks
ago. There have just been two days of quite heavy rainful here (the great
British summer) and today I noticed that there are small clumps of white
eggs around the edge of the pond, stuck to the edges and just on the water
surface. The eggs are about 3-4 cm wide and in bunches of 6 or 7. Does
anyone have any idea what they may be?

Thanks for the advice,

Pete
