Soft rot initiated by insect feeding.
Feeding damage from starlings, that peck deep into the flesh.
Hail damage.
Possible green peach aphid damage to nectarine.
Damage caused by fruitworm caterpillar feeding on the peach.
Earwigs create deep feeding holes. Note the black specks; they are excrement.
Late-season coryneum infections.
Corking of the interior flesh caused by cool post-bloom temperatures and a light crop.
Cat-facing injury caused by either lygus or stink bug feeding.
Injury to peach flesh, followed by infection of brown rot.
Woolly apple aphids have a thick cottony coating that can be impervious to insecticides. They feed on branches and twigs through the summer.
