Saw a lot of these on a house pond with fish. Are they safe?
Signature: Water bug?
I found out its a mosquito larvae
You are correct that this is a Mosquito larva. They are commonly called Wrigglers because of the way they move through the water. Home gardeners in California, where most gardens get frequent watering, are warned that even the smallest container of water can become a breeding ground for Mosquitoes. It is quite interesting that the fish in the pond are not eating the Mosquito larvae. If the fish are Koi, they might be too large to be interested in such a small creature, but introducing mosquito fish might help control the situation.
