Small Black Worms Take Over Koi Pond
We believe the small black organisms our reader found in her pond are either leeches or black fly larvae. Both are similar in appearance, though leeches are slightly bigger, and both are commonly found in ponds. Neither species are considered invasive and neither should damage her pond or cause any problems with the fish!
Worms or Larvae in a Pond
We received an interesting and fairly perplexing question from a reader yesterday about “a bunch of small white worms or larva.” (It should be “larvae,” with that bizarre Latinate ending to indicate plurality, for the record.) The worms or larvae were found in a pond that is used by cattle at a dairy. The creatures in the pond are about an inch long and they have a tail that is about as long as the body. The reader sent a nice (if confusing) picture of the worms or larvae, which we have included below. What are these worms or larvae in the pond?
