Several of these characters have taken up residence on the garage ceiling in the last few days.
I suspect they belong to the family: Parajulidae.
This, of course, is the head end; the rest of the body just goes on and on as a series of 4-legged segments.
The body is a highly reflective cylinder and I am finding it difficult to photograph. This is the best so far, with 2 flashes at the anterior end diffused through a styrofoam cup.
Note the clear mid-line region bounded by an upper and lower duller bands. These dull bands are in focus and quite sharp but on a curve that appears to cause flare in the lens.

Re: Millipede invasion
How about using masking off the section of the styrofoam cup that is reflecting in those areas with the ProtoStar flocking. Alternatively, how about removing the styrofoam diffuser and using flat panels to reflect the flash onto the subject.NikonUser wrote:Several of these characters have taken up residence on the garage ceiling in the last few days.

Re: Millipede invasion
I don't think this is flare. The grayed-out bands looks like a specular reflection of the wrap-around foam diffuser. The clear section down the middle is where dark environment is being reflected, like the camera lens. It's just like Charlie's avatar with the wigged-out eyes, except reflected from a cylinder instead of a sphere.NikonUser wrote:Note the clear mid-line region bounded by an upper and lower duller bands.

Shiny cylinders are tough.
I suggest not using a wrap-around diffuser. Instead, position diffuser material close to, but not touching, the head of each flash. You want the diffuser positioned so that the flash casts a fuzzy-edged spot of light on the diffuser. That way the specular reflections of the diffuser will also have fuzzy edges, so they won't look as much like bands or spots.
You might also want to consider using crossed polarizers to kill or subdue the specular reflections. That's not practical with a wrap-around diffuser, but it's pretty straightforward with a planar diffuser in front of a flash. See HERE and the links therein for some theory and practice.

Thanks Elf and Rik.
Tried various setups but not crossed polarizers; never did eliminate the reflections. As I will probably never again try to shoot a shiny cylinder I will stop 'playing around' with these beasts.
A single flash above and as close to the lens as possible, diffuser on flash + double layer of tissue diffuser + flat white panels opposite side of flash gave an OK image.
But perhaps the best so far (and the final attempt; I'm getting lazy) was the chicken egg as a diffuser around the millipede, below:

'white' = full frame,
