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.
One of the more powerful and easier to get PokÃ©mon in the game are the evolved forms of Eevee, but unlike most other beasts in the game, Eevee has three different evolved forms in PokÃ©mon Go. Eevee can become the fire-based Flareon, the electricity-based Jolteon or the water-based Vaporeon.
