I don't know what to say. My A.mauritanicus that molted to 4th instar on July 12, 2006. Is now molting again to 5th instar (August 9,2006). It only took the guy 27 days to molt from 4th to 5th instar. Molted to 4th on July 12, 2006 then I power fed it after 8-9 days (July 21,2006). So that gives him almost 3 weeks to keep eating and molt after. Well, time to feed the other guys hardcore.
I'll provide pics later.
