No point in not just ending this. 2 Wing Attacks should finish it off before in can beat you with Bug Bites. However, if that doesn't work than you're pretty much out of luck as you will be incredibly low on both health and energy, but then again, there is not much it can do back to us. Actually, lets conserve energy first by Roosting to break the consecutive use chain, then do the wing attacks. But if it tries to Bide, the disregard the healing and just beat it down before you get destroyed by Bide.
