Ugh... I walked right into an emperor butterfly and lost it. Then I tried to catch another one and missed - ack. Are they a little tricky timing wise?? I have no trouble catching the other bugs.
I have seen and caught most of the rare bugs and fish. I'm missing the emperor butterfly, which I did see once, however, my phone lagged at an unfortunate time and I wasn't able to catch it. The only other rare bug I haven't seen at all would be the jewel beetle.
