Hi I'm familiar with Belphariceridae larvae we found tin the freshwater of Haute Ardenne Waterstream close to the German/ Belgium border in Signal de Botrange-Mont rigi region. Not often but we know this larva living on the rocks fixed by this vacuum sticking suctorial disks and the well visible cephalothorax Here I have found a strange aquatic larva unknow in a sample of freshwater collected with a lot of other invertebrates in a very streamy river (high water after flood, so possibility of drift) At the beginning I believed it was a blephariceridae larva... but The body of this larva seems to be divided in 9 abdominal semgents plus tree thoracic parts, the head is well separated from the body and seems to be a aquatic moth larvae head. It had 4 protuberances each with a kind of spike The colour of the larva was white and the pictures made of it give a yellow color caused by the lighting used (LEd) to illuminate the organism observed with a stereomicroscope and after put on a glass slide for microscopy (x70). The length of this larva is quite 3 mm maximum. It had no legs but something like little hooks on the second ventral thoracic segment. The end of the abdomen is terminated with a bunch of hooks and the apical end is composed of two longs spicules I have found two larave in the whole sample composed of 45 different invertebrate species (about 1000 organisms) It seemed to me to live easily in the water as it lived more than 4 hours in the collecting tank If you could help... with these pour pictures I had just 2 minutes of video... and I have lost the organisms without better pictures So... thanks you if you could help and give me a direction Could it be a diptera larva ? Coleoptera larvae ?   Hooks are situated on the last abdominal segment on the ventral side

Ceratopogonidae, either Forcipomyia or Atrichopogon, but I think it is most likely the latter genus. |

I thank yo a lot, it seems very matching with litterature about Atrichopogon This larva is not visible in the main Aquatic Invertebrate Handbook (TACHET) we are often using here in East Belgium and in France, but we can find it in the old litterature like the Henri Bertrand, Insectes aquatiques d'Europe. Other pictures will follow SDS |
