The pictured moth? is killing my grapefruit leaves by taking 1 bite on the leaf right at the junction of the stem and the leaf. in a day or so the leaf starts drying up to the point that it falls off the tree either by a gentle tug or a 15 mph breeze. my trees are loosing leaves--mature leaves only--faster than these nice spring days can blossum out new ones. i am worried that when the bees come and fertilize the blooms that there will be no leaves to shade the fruit or the trees will just die. there seems to be around 8-10 of these moths on ea. tree--trees are mature and about 12-15 ft. high. what should i treat the trees with--trying to keep it organic if possible--don't want the trees to die...
