I did just find that the Lvl 80 red bee gives 89 while the lvl 80 blue bee gives 99 but that is to be expected with them being different named bosses.
From what I have seen, at this point the blue boss only comes in lvl 80, have not seen any lower or higher as yet. The red boss also does not seem to go higher than lvl 80 either. I'm guessing we will see higher lvl blue bosses for the second part of the event but to be honest with how fast i've been collecting I think i'll have completed the event way before the second phase.
