This is an ant woodlouse, not a brilliant photo but unlike other woodlice they don't stay still.

I lifted up a stone and they were in an ant colony and the light made them run like crazy.

I was wondering if I could have used an umbrella so that they were in the shade maybe something like this

I also wondered if I could get another benefit by taping a slave flash to it and and using bounce flash. Has anyone tried this in the field?

I see no reason it wouldn't work. A bit large for my purposes but should do the trick. When the subject allows for it, often early in the morning, I use small panel diffusers like this http://www.amazon.com …r-Diffusion/dp/B00KN6X5E​Y (external link) to modify or redirect ambient light and/or flash. As for bouncing flash, yes it is a valid technique in the field and can be used to good effect for lifting shadows. Typically these techniques are limited to static subjects, still scenes, and/or sleeping/lethargic insects as it takes time to set things up and dial in the desired lighting angles and exposure levels.

Not sure because the subject might not stay still unless it's in total darkness. You'd also want to get the umbrella close to the subject if you're bouncing a flash into it for the light source. Get it too far way and you'll might end up firing the flash at full power (slow recycle time and difficult to freeze motion due to the duration of the flash). You'd also more than likely come between the umbrella and the subject, so you'd end up blocking the flash.

The umbrella is only going to be £5 so it is worth a test, by the way I was thinking of using as a secondary flash as back fill.

By the way, the subject is something that has also fascinated me sadly I have a very small garden and I don't have any L Niger colonies under stones nor space for any stones. If anyone has a large garden a few decorative stones will give you an opportunity.
There are surprisingly few photos of it on Flickr
