In my four years of ponding in central Florida, I've utilized several types of plants. Each has its unique strengths and weaknesses. I've been using submerged potted Alisma plantago for its stately, high-reaching leaf stalks and pretty white flowers - as a contrast to water lettuce and water lilies, both of which offer no real profile above the pond surface (except when the lilies blossom).
Up until this year, my Alismas have exhibited no problems. When leaves would die, their stalks would fall away and fresh stalks take their place. There did not seem to be any diseases or insects that would plague them. However, this year something has been eating my Alisma leaves. I can only assume it is an insect or larva of one but I have never encountered any creatures on them. As the photograph indicates, the leaves tend to be eaten right up to the veins, which are left intact. Eventually, the leaf looks like a skeleton with only the vein structure left behind.
Any ideas as to what could be eating them, and if so, how to treat them?
