I know it’s not your usual fare, but I’m hoping you could help identify this larva. I found this specimen living in the filter of my tropical aquarium.
It is about 12mm long, and was not present a month ago. The water is hard, with a pH or 8.0 exactly, at around 25.5 degrees Celcius.
There were three specimens in the filter, all around the same size, but no evidence of any others anywhere else.
Thanks in advance.
This immature Damselfly is known as a Naiad. It was probably introduced to the aquarium on plants.
