Codling moth. Codling moth larvae are an important pest of apple trees and to some extent pear trees. The female adult moth lays eggs on apple fruitlets in late spring, and the resulting larvae burrow into the developing apples. They damage the inside of the apple.
Keep on giving it Haircuts and it'll evolve eventually. Eevee can evolve into an Umbreon at and between the levels 2-99. It needs at least 220 Happiness points but from what you said earlier (trusts you), it means that your very close to reaching that level. Makes sure that you level it up so that it evolves. If you don't level it up, then it won't evolve.
Anonomus1 answered: To evolve an Eevee into Umbreon or Espeon quickly, you need to put a Sooth bell on it, when give it the berries that increase friendliness while decreaseing stats. About 10 - 15 will fulfill this even with a new pokemon. then level up in day for Esp or Night for Umb.
