A bit late but looks like a male to me

I just heard from the supplier, they're confident these particular nymphs were L2 when I bought them. That means the one in the photo above is only L3, the other, which I'm struggling to get a detailed shot of, must be L2 sing dog hasn't molted yet, which would explain the great difficulty getting a clear shot of all segments since they've not formed nearly well enough yet. Can they shed a week apart of they're the same age? Should I be worried?

These little Mio's are quite difficult to sex , you do have good pics which certainly help .......... I wait till L4/5  when sexing .../.  S
