Bug Encyclopedia

What are all of the bugs in Animal Crossing New Leaf? I have exactly 60 entries in it I just need 12 more bugs, I only know 3 of the bugs that I'm missing, but I only know when 2 of them are out. I know that I need the Petaltail Dragonfly, the tarantula, and the scorpion. Can someone tell me the whole bug encyclopedia, and tell me when they are out, please?

This might help you! It has a list of every bug in the encyclopedia, and I think they're in the same order as they are in the game.
