CO 2 is pretty commonly used as an anesthetic in genetic research studies of fruit flies. It will knock out most insects. If you have them in a small container, a short blast injected into the jar will usually do the trick. Ethyl acetate is one of the substances most recommended by entomologists for...

Rik... thanks for posting this, it's fun to see peoples set-ups. Probably there are a lot better ways to get the same or better results, and I hope to hear about them next week. I'm not so sure, looks good to me :wink: Since I suspect there will be interest in this, I hope you don't mind if I throw ...

I am at a loss at why it is so popular You are not alone! I have had a TV as long as I can remember, but when I hear the statistics of the number of hours the "average" person watches each week and compare it to my viewing I am astounded! I have never even seen an episode of American Idol, Desparat...

Amoeba mealtime

I watched this small green flagellate approach and move up against the surface of this amoeba. Big mistake. The amoeba slowly extended a welcoming pseudopod around the little fella, and next thing you know it's a food vacuole! http://www.krebsmicro.com/forumpix/4panelamoe.jpg http://www.krebsmicro.c...

Cyclops (Copepod) "tailfeathers"

The patterns formed by these rear appendages on these tiny crustaceans are fun to examine. While I normally avoid the colorful results possible with the DIC slider, opting for a more "natural" look, I could not resist trying a couple of colorful abstract renditions of this subject. Olympus BHS, Olym...

The monkey part is puzzling... but not the Lewis part: Its species name honors Captain Meriwether Lewis who was the first to collect the plant near Lemhi Pass on the border of today's Montana and Idaho, probably on August 12, 1805; it may be found in the same place today. It was named by Frederick P...

Rik... I had to go back and check since I actually did it last year. There were 94 images in the stack. The background originally was a solid blue, but I fooled around digitally putting some slight cloud "texture" in it.

Subalpine Wildflowers (closeups), Mount Rainier NP

Three wildflowers from a quick trip to Mount Rainier NP. The first is a particular favorite of mine... I'm always amused when I look closely at the tiny, perfect, floral elephant heads .

Magnolia

I guess I'll get it started here with this simple picture of a magnolia flower. They don't last long... seem to be falling apart before they are even fully opened, but they look and smell great.

Mosquito head from very large stack

This is the head of a (Culex... I believe) mosquito. As you can see a goodly portion of the mosquito head is made up of "eye".
