In my fishing net on Tuesday, I also found some of these. They were difficult to manoeuvre into the jam jar for photographing, so I lost a couple. At first I assumed they were mosquito larvae, but I realised that they didn’t have the hammer-head shape, rather a question-mark silhouette as you can see. Also, once in the jam jar, this one moved like a caterpillar, looping along the bottom, rather than wiggling zig-zag style through the water as I would expect a mosquito larva to do. I’m still not 100% sure, but I think this could be a phantom midge larva so-called because it is transparent – you can see its eyes and insides only. You can get other midge larvae that aren’t transparent and some look more like worms.
