Water lettuce hosting growing population of tiny black bugs; pics included

Update:the bugs on the water lettice have pretty much vanished. I expect they will be an unwanted seasonal visitor in my pond.

Good to know, and thanks for the update!

This is my first year having a full set of water lettuce... I find them much more annoying compared to hyacinths and frog bits or duckweed. I wont get them next year. They get damaged by a lot of things way too easily.

Yes, they grow and multiply quickly. The pond requires a lot maintanance because of this. I keep it because they help against algae growth and provide shade for my fish.
