Mantis faces
Looking through some older images while doing a backup, these mantis portraits caught my eye. They are from stacks of 10-15 images taken through an Zeiss Stem 11 APO dissecting microscope and processed with software provided by Zeiss (pre-Zerene days). Lighting by fiberoptic light pipes and coffeecu...

Thanks, Bruce - very helpful. The name certainly matches the behavior.

Re: Some amoebas
Thanks, Bruce. Buoyancy control - that's a clever adaptation. I'm learning that amoebas are so much more than moving, morphing blobs. Lou, the nightmare scenario is about right. When it was some distance away, that amoeba seemed to change course to go toward the algae. How could it 'know' that food ...

Some amoebas
These are all from my neighbor's backyard pond. The IDs are all tentative - any help with that would be much appreciated. DIC and high-speed flash (the latter hardly necessary to freeze movement of these subjects). 1. Arcella sp. Empty tests are common, but I've much less frequently seen one with th...

Re: A Choanoflagellate and Lacrymaria
Adding a photo to show the length of the choanaflagellate flagellum (hence the odd orientation). Also this one had just ingested its lunch.

Re: lighting cage with CAMVATE clamps and arms
Rik - Thanks for all the info on your cage. Looks great, highly practical. As others have noted, your post has stimulated plans to build something like it (maybe with 10-series t-slot for added rigidity/stability, but expensive). Thanks, too, for the link to the Allan Walls videos - quite extensive,...

A Choanoflagellate and Lacrymaria
A couple of photos of creatures living in my neighbor's backyard pond. The first is a group of choanoflagellates, possibly Salpingoeca sp., sitting on a spherical algae, Golenkinia sp. (I think). A quick bit of research turned up that the choanoflagellates share a common ancestor with all multi-cell...

Re: Alternatives to Equipement Exchange or eBay?
I've had good luck with the Fred Maranda Buy/Sell board. Macro equipment of various sorts shows up occasionally, e.g. Novoflex bellows, macro focus rails, flashes of all kinds, and occasionally an enlarger lens or other exotic glass. No microscope equipment that I can remember seeing.

Re: Mantis eye cleaning
Really interesting, informative SEM! It's easy to imagine those paddles doing a good cleaning job. You motivated me to look for more info, and I found this summary, quoted in a 1990 paper on the mantises of New Zealand: "... the anterior end of the fore-femur is manipulated by the mouth-parts, and p...

Mantis eye cleaning
Taken in my photo studio, i.e., the dining room table. A praying mantis nymph grooming. Creobroter sp. Body length approximately 15mm. The second photo is an enlargement showing the brush of thick hairs on the leg that the mantis uses specifically to keep its eyes clean. Nikon D800, Voigtländer 125m...

Denmark butterflies
Going through some older images, I found a few that might be worth sharing. These butterflies were in a field near Odense, Denmark.

Jumbo
Discovered in my neighbor's backyard koi pond. An aggressive predator. Watched one devour the insides of a nauplius.
