Xystocheir dissecta is also known as the Redwood Xystocherini.

It was difficult to get an image of this tiny millipede that was not just a blur.

 

 

This may be the same thing farther after molting? This was moving too fast to be sure.

Paeromopus angusticeps buttensis is one of the millipedes that live here.

It was difficult to photograph this due to it constantly moving so fast that the legs and the body were a blur of motion. The images with detail were obtained by placing the animal in a refrigerator for half an hour prior to taking the photographs.

 

A Harpaphe sp.

This is also known as the almond-scented millipede due to it producing hydrogen cyanide as a defensive aid.

The roughness on the surface of this first animal is just tiny dew drops.

This one from last year is either a juvenile or has just recently molted:

Below is the same one but under UV.
I first noticed a Harpaphe millipede on a dark night wandering around the forest looking for black-light friendly mushrooms. It was apparently sleeping as at first it appeared from a distance to be a cluster of blue bristles. As the light got closer it began to move. It seems clear that black-light bothers arthropods that fluoresce as they actively try to get away from it.
