So many people not at all bug catchers answering this with sass...

The bees are next to friggin impossible to catch. I've only gotten one all year (and not for lack of trying). They are much faster than before, and take a more slight path towards you, not so much a straight line that makes it simple to catch. Additionally, the lag causes them to jump around and become more difficult to catch. Other bugs do not have the same issue, being relatively slow and less affected by the lag.

Also, though I had mentioned it and it MAY be intentional, the butterflies and other insects seem to have lost their 'scared' mode which was triggered after you swing and miss at a short distance. I believe this was caused by some one not switching back the 'ghost' bug behavior, as the two things acted very much the same.
