I think I pinned a butterfly while it was alive. Crap

I collect butterflies and I put it in a killing jar for 1 hour and then it looked dead. I then pinned its thorax, 30 mins later its wings were moving a bit. Does it feel pain? I hope not. What do I do now?

Will the butterfly die soon?

just let it be. It most likely didnt feel much if it was so close to dead. Also, it could have just been its nerves still making it move after death. An example is when my dad fillets fish, we through salt on them nd they will move, long after they are deheaded.(its rather sad)
