Flea beetles are the most evil thing! The last couple of years I've managed to protect my arugula and other brassicas with row cover when they're small but somehow, despite having the entire edge buried, my tatsoi, bok choy, arugula, chinese cabbage...ALL turned into ugly lace by the little buggers. I've heard they're less of a problem in the fall and I hope that's true because I didn't get squat out of those crops so I'll be trying again this fall. Stupid bugs! (Can you tell I don't like them? 
)
