Bejeweled Stars Level 2956 - Bombardment by butterflies in lower section is impo

This is just impossible to complete. Been trying for about a week and only getting about 4/5 moves before a butterfly escapes. Any help or tips would be appreciated 

Have you beat level 2956 yet? Why oh why do they make it so impossible?! It makes me want to quit bejeweled after years of playing !
