Examining and enjoying ditch water

I've done this numerous times in my life, starting in my pre-teen years and as recently as a couple years ago.  My usual focus has been on raising tadpoles to frogs, while the insect life was a secondary phenomenon.  I think I'll it this again this spring, but with more mud.  I'm pleased to see that so much success was achieved with a sealed jar; presumably the vegetation was enough to oxygenate the water.  That's nice, because these jars do become malodorous when left open indoors.
