This species is quite rare within the hobby, they are one of the two species in the iberoforimca genus. Queens are beautifully coloured and are predominately a shade of dark red with a black gaster and golden/yellow stripe and are 9mm, workers range from dark brown/black to red and are 6-8mm. Formica can be a skitty species if disturbed too often, they definitely benefit from a semi/full natural set up. This species should not be kept with a closed test tube as they spray formic acid readily. There incredibly fast and are a joy to watch, they love their sugar! Proteins there not too fussy and will scavenge meal worms / wax worms / roaches and fruit flys. Colony’s can reach 1500-3000workers.
