I saw a dozen or more clusters of what I think are insect eggs attached to a few vertical sticks protruding from a small pond, and a few more to stalks of grass nearby. Location is in Hsinchu County, Taiwan, end of March, fairly good weather these days in the neighborhood of 15-22 C.
Each cluster consist of a group of roughly 150 spherical hot pink colored eggs stuck to a surface, each about 2.5 to 3 mm in diameter. One group was deposited almost completely around a stalk of grass on land next to the pond, and several others were deposited on the side of a stick from a fallen branch sticking out of the water.
- Is it possible to identify what kind of insect produces such clusters of eggs?
- Is there any explanation possible for the "hot pink" color? I suppose it could be a general "don't eat me" signal like these big juicy red bugs but it's such an artificial looking color, I've never seen it anywhere in nature, at least that I can remember.

update: This answer suggests that snails are the likely culprits, and so I returned to the scene of the crime today and caught them red-handed, or in this case "pink-footed".
