Nice pictures. Is that last one a Buthacus arenicola? Do you have any information about your B. jacksoni? I am currently trying to figure out the ID on a similar scorpion. I believe what is being imported as B. jacksoni will later be proven to be a few different species of Babycurus.
The bottom one is a california gold scorpion smeringurus species. I have looked in alot of different places for B.jacksoni info never found much too go on. They have a care sheet in ivertcare.com but iv never read a big write up on them anywhere.
