Good Afternoon,

How are you?

Thank you very much to everybody who posted on my other thread about these larvae. Since then, several of them have successfully molted into pupae, and I have gained some extra information.

It has come to light that these larvae are algophagous, and are full sized when 6.5-7 mm long. To my untrained eye, all the larvae that I have collected seem the same; however, two different pupae have emerged from the larvae. One larva pupated on the side of the container, above the water line, and has no visible breathing tube. All the others, however, turned into aquatic puparia with(I think) breathing tubes.

Many thanks to Atylotus for identifying these larvae to Family level. I am hoping that it may be possible to narrow it down further, though. Is there any way to do so?

Thank you in advance for your assistance,
Johanan E. Viljoen
