These  are gorgeous Phidippus regius Bahamas males. 
They left the nest  1/26
They are 10-12 mm 
Some of these do not have ear muffs, not all Bahamas males do, but this wont make any difference to breeding, If that's what you want to use them for, as there are always a percentage in each batch that don't have ear muffs.
They are feeding very well on green bottle flies. 
Bahamas are one of the many Phidippus regius locales. 
They are an easy to care for jumper. 
Please remember to provide a bright white led light directly above the enclosure for their wellbeing.
