PIc Heavy, but this is a neat time-lapse set of pictures from a 40 min cell phone video of P. vindex feeding.
I had been too caught up watching them do their thing before it occurred to me to film them, but this is still the bulk of of it.
Male's tunnel is on the right, the females on the left.

The male has now cut away a small section and is working on bringing it down into it's feeding chamber.

12:51
Notice the female's progress, versus the male's progress, particularly give the size of food on either tunnel.

18:07
The female is now done storing the excrement directly above her tunnel, she comes out, waves her antennae in search of more, and realizes there is a small amount close to her.
18:53
She finds a small amount very close to her tunnel at 19:07
And begins working away, using her "shovel" clypeus to cut at it from underneath.
19:35
Unknown to her, that little piece of food belonged to a major male that tunneled next to her, she gets startled and mounts a quick retreat to her tunnel.
