Continuing my freshwater picture library ”boost up” , I got around to doing a couple of Caddis larvae today. These are more for interest really as not much is going on the forum at the moment.
All caddis larvae make unique cases which can often aid ID
This species is interesting as they usually use vegetation or empty snail shells. (It is Limnophilus flavicornis )
However it seems the top one in the shot has started with vegetation and then for some reason changed its mind ! As you can see the lower one is nearly all shells.
They usually have a twiggy bit at the end as this helps to stop them getting swallowed.
The other interesting point is that they have used various snails. There are a couple of species of small Planorbis- the whorled ones but also a load of freshwater cockles (Pisidium species) These however are not dead but fully working as you can see the foot out on a couple of them ! So there!- how to get a free ride around the pond !!
D7000
Nikor 40mm Micro
320 ISO On camera flash f18
Slave to ceiling
60% of full frame.
An hour cloning out spots, minute bits of detritus and air bubbles ! It’s a pain and that’s with using still water !

I'm fascinated by these images of yours, John, as you may have guessed. I intended trying something with the salamanders that breed in a couple of vernal pools but we have had such a dry spring, until now, that they dried up long before anything was viable. Next year!

Another very interesting shot, JR. This is the first time I have seen a Caddis Larvae up close, the structure of the case is amazing.

I,ve managed to get hold of a very small tank filter which certainly helps with cleaning the water up !
