There are a number of insects with the piercingsucking feeding habit that can cause deformity and catfacing type injury to pome and stone fruits, including Iygus bug, stink bug, and boxelder bug. Cat-facing injury is caused by puncture-feeding in flower buds and young fruit. The result is unsightly dimpling, deformity, and scarring of fruit. The name "cat facing" comes from the distorted fruit shape that resembles the puckered cheeks of a cat. In addition to the insects discussed in this section, some aphids and the campylomma bug can inflict similar injury.
