Here are 4

Most are manually focus stacked, then run through Topaz Sharpen AI, then fiddled with some more in Gimp.

A ground crab spider, probably Xysticus sp.

Masked hunter (that is the name), Reduvius personatus. This creepy assassin bug came to the porch light one night.

Mosquito larva. I don't know the species.
I had a couple cheap picture frames and sealed the glass into the frames and then glued them together to make a narrow aquarium. Of course the frames on one side are removed so the aquarium is open on top. It still slowly leaks (I need to find something to assuredly seal the #$#% thing, and am open to suggestions). Here I photographed through the thin glass. Mosquito larvae proved a lot harder to photograph even so, since they do want to move around a lot. Bigger insects will be better, and I want to do more of this sort of thing.

A simple very young grasshopper nymph. I think the red-legged grasshopper (Melanoplus femurrubrum).

Hello Mark,

That mosquito larva is just great. Beautiful details
Not surprised that tis one is a challenge, but that's what keeps us going

Thanks for sharing!

All the best from Norway

very well done on the Mosquito, thanks for sharing the "making of"

Love the mosquito larva pic. For sealing the "aquarium" perhaps silicone?

Love the image of the mosquito larva and your technique for isolating it. Try silicone rubber as an aquarium sealant. Small quantities are available in toothpaste-type tubes. Cut off the tip of the nozzle, apply a bead along whatever seam you wish to seal, work into the seam with a tool or fingertip, and remove the excess. Has a vinegary, acetic acid odor before it cures.

I used aquarium sealant. But it still slowly leaks. I favor using some kind of liquid sealant that can be poured in to the bottom.

On a rather separate note, another scheme in mind for a different mini-aquarium is to make one from glass screen protectors that go on cell phones. I have a bunch of them that are unused, and the glass is very thin.
