Phidippus regius 'Apalachicola' is a specific locality of the Regal Jumping Spider native to the Apalachicola region in the Florida Panhandle. Known for being slightly larger than the standard P. regius, this variant is a favorite among enthusiasts due to its striking appearance and inquisitive personality. 
 
Key Characteristics
Size: Adults typically range from 14–18 mm, featuring a stocky build suited for agile hunting.
Appearance: They are famous for their iridescent chelicerae (mouthparts), which often shimmer in shades of green, blue, or purple.
Sexual Dimorphism:
Males: Consistently black with white markings and typically green or blue chelicerae.
Females: Highly variable in color. They can exhibit "white phases" with pale cream or snowy white coats, or "dark phases" with rich espresso, grey, or brown tones.
Behavior: These spiders are diurnal (active during the day), curious, and display advanced intelligence for their size, often interacting directly with their keepers. 
 
Care and Habitat
Enclosure: Requires a vertical terrarium of at least 20 x 20 x 30 cm to support their climbing and jumping instincts.
Environment: Should include various levels of branches, leaves, and hiding spots.
Feeding: They primarily eat flying insects. Slings (babies) may eat daily, while adults typically feed every 5–10 days.
