| I found some eggs under a lily leaf, they are not snails they look like small frog spawn, i have put them in a small aquarium with some weed and pond water. I have minnows and golden orfe, which do you think they are. derek |

| Is it anything like this I have found on my lily leaves & water soldiers? |

| They are very similar except i only have one little mass with about 20 eggs in, have you any idea what they are. derek |

| in that case probably the eggs of the snail physa acuta http://www.applesnail.net/content/snails_various.php#Physidae |

| If they are similar to mine then I believe your jelly blobs are home to a colonial microscopic animal - Ophrydium- a sessile ciliate that is found embedded in a gelatinous matrix, they are often green as they may contain symbiotic algae. I have shown some of my microscope pics on ealier posting. |

| I have to agree with Mike--otherwise known as the attack of the yellow globules!! |

| I will have to save this otherwise I will forget http://protist.i.hosei.ac.jp/PDB/Images/Ciliophora/Ophrydium/sp_02.html |

And are these a good thing to have living in your pond or does this ophrydium bring problems for other animals?

| No I dont think it hurts other animals, but thro the jelly like eggs clustering on lily leaves, plant stalks, oxygenators & others (partic water soldiers)it smothers the plant and can kill them. I'm hoping mother nature takes its course & it vanishes. It makes the pond a mess & is not nice to have. I'm interested in hearing from any others with this gelatinous goo!! |

| They do spread and are not very attractive, but they can be kept under control with a fine mesh net. They are very oxygen hungry, and I have noticed that I don't see other things feeding off it or living in it--so it doesn't add anything to pond. They ate the water starwort this year as well as the water soldiers (both not easily accessible with the net), but have not bothered other plants. |

For those interested I have discovered the actual blobs are a colony of cyanobacteria,of the genus Gloeotrichia.
Plenty of inf on the web. |

| That's the name I couldn't remember--I was told what it was when I sent a sample to an expert in Scotland. Amazing what you can find on the web (as well as in the pond!) |
