Luis, that's a smart suggestion....think simple, keep it simple

I will filter with a 53-11micron and something will happen.
And what about the best microscope for looking at the pods? I have a monoscope Bresser biolux 10X-1280X but the damned animals move on the slide even with the overslide (not sure if this is the proper name of the small piece you put on). I clearly saw those but just as a meteora under the lens. I read you dry the
larvae without damaging them. I tried with pods but I could see only crystals of salt. I tried also with acetic acid as I read somewhere that could inebriate the pods but again without great success.
I know this question has been made here and there in different forums so again if there is one already self explicative for this, just remind me that.
