noob in need.. help with ID please!!

I currently leaving in Barstow, Ca which is Mojave desert area. I always wanted a scorpion so i did my research got everything i needed went out to the desert to find me one and came back with 3 little guys lol problem is I'm having a hard time identifying 2 of them. So i need some of you guys expertise on the matter..

I know for fact the bigger one is a Hadrurus Arizonensis the other 2 i dont know if they the same or they are bark scorpions. here are some pictures sorry for the quality i didnt wanted to disturb them during the day so i took them at night when they came out

this is the desert hairy



this is the 2 i need help with

number 2



this the 3rd one wich looks a lot like number 2



Thank you in advanced!!

The Hadrurus arizonensis is correct. The other other two however are not bark scorpions.

For picture number 2, I want to say Smeringus mesaensis, but the tail makes it look like a Vaejovid. It may just be the lighting, however.

For picture number 3, I believe it is a Hoffmanius spinigerus.

Thanks haha. The thing is you can do it by memory and I have to use pictures haha.

Sometimes I still use pictures with species I'm not sure with but these common ones I can pretty much do by memory but hey I gotten a few wrong I thought a freshly molted C.sculpt was a dune scorpion.

Good to know I'm not the only one that uses pictures haha.

Wow thanks for the quick answer. At first I was like they all look the same to me, now that you say that i did my research and I can see the difference now lol and I think your right on the spot. One thing i forgot to was to describe their characters like number 2 I research the dune scorpion and i think your right hes lighting fast and doesn't seem to like burrowing so much he rathers be on top of rocks and wood and hide upside down..the 3rd one i can see the stripes in the tail now lol.
unfortunately my hadrurus is being eaten by a much bigger hadrurus i got me last night since them 3 seemed to get alone pretty good i made the mistake of thinking this big guy/girl was the same but he was hungry and it was so happy on his new home that he didn't know what to do he had one cricket in his mouth another cricket in one arm and digging a burrow with the other all at the same time then my little hadrurus got to close and well ill add a picture of my new addition on the other hand I'm separating them because i don't want him to eat the remaining 2

this guy/girl is big I don't know if is going to get bigger

Its ok. It's a beginner's mistake. Hadrurus sp. are never communal and by the picture above, you basically were just feeding it. Just keep them separate, do research, and ask questions in order to keep your scorpions healthy and happy.
