20 Giant Silver Bullet Springtails "GSB" (Pogonognathellus dubius)
Among the largest springtails in the hobby. Blow on their antenna to see them curl into spirals, a unique characteristic of the genus. They have very relaxed personalities and mostly sit still, great pet springtail species. You will receive 20+ mixed juveniles and subadults, sometimes adults. Maximum size may take 1-2+ months to be seen.
