A few days ago, I noticed that my tomato plant was losing all of its leaves (as it eaten) and one of the tomatoes looked eaten. I assumed birds were at it. Last night, I went out to tomato plants to water them and noticed a nice FAT tomato worm with what looked like little egg sacs all over his body. The stripped plant is now explained. What is still a puzzle to me is how the heck it got there. My balcony is 4 storeys off the ground!
