Unknown instars*
These two shots are of a tiny Phidippus instar. It has orange on the head
and the one below does not.
These two shots were taken a few plants down down the road. This was a bigger spider (although
still small) and the orange on the head had faded to almost nothing and the black on the back
has all but disappeared. I still think it's the same species. I saw two mature Phidippus
this same day -- Phidippus Johnsoni and Apacheanus. © Carol Davis, 8-30-2009,
