Hello lovely Miss Perez,
Macro photography isn't always about the quickness of taking the shots and mostly is not comfortable. I think that if you want to start doing macro shots you need to see what lenses you already own which would allow you to get closer to the subject without ruining the picture, scene or, in your case without scaring it.
For bees and butterflies I think you'll do great with a zoom lens and if that lens has also macro option you're in business. But if you want to advance a little bit more into this, another important thing to consider would be light and how can you have it into your shots if you want to shoot let's say above f5...
I'm looking forward to your progress and some lovely shots.
Best regards,
AMV.graphy
