This is my current water beetle/bug photography container (in answer to Tim's question). The plastic is 1/8 inch thick and came from TAP Plastics. I glued the sides together with solvent cement. It was somewhat messy because the glue dried very fast, I'd end up with a leaky container, I'd have to glue it again, test for leaks again, etc.. Glue dried in places where I didn't want it to dry. I couldn't find a pre-made container the size I wanted; that's why I made one.

Actually I've made three of these so far. The first was way too big and then I stupidly cleaned it with a scrubby sponge, which destroyed it for photography (scratches....). The second one was not as large but is larger than this one. I'll use it eventually but so far I haven't needed one that large.

I'll post a photo of this container in use later -- right now I don't have an insect handy. I've been putting some sand on the bottom to cover up some of that extra glue. Also, depending on the insect, some plant material -- insects like to grab onto or stop next to plants and pose. Then behind the container I put a piece of non-white paper or something to make the background something other than black. Also I learned if I'm using this in the field it's not good to use the water out of which the insect came -- it usually has particles in it that become horribly magnified with my MP-E65mm lens (and can obscure the insect).

I'm always removing bubbles that form on the inside sides of the container ... most of my photos so far have had some bubbles anyway (like this one).

I don't think this it the last container I'll be making .... it's all an experiment. Here are some other photos shot this way: 1 and 2.
