You need to be careful from all Insectors in this round. Starting from Tornado Mantis that can attack multiple targets if your Insectors are close to it. Don't leave any gap near your King because Hop Skipper can leaps and attack from behind. Also don't forget about Fishface Beetle it will still shoot from behind if your Insectors are in range. Best startgey is to take out Hook Bee, Hop Skipper and Ladybird first. That way you won't have trouble getting rid of the remaining ones.
