Trying to figure out what's eating leaves of the Johnagold apple, which I am giving one more year to get better. Cleaned out under, pruned heavily, opened canopy letting in light, much new leaf growth this spring.
Leaf has signs of Leafroller:

The larvae of the fruittree leafroller feed on leaves, flower parts, and sometimes young fruit. They are pale to dark green with a shiny black head and are about 3/4" long at maturity. Typical symptoms of leafroller feeding include leaves that are rolled and tied in place with webbing and shallow surface damage on the fruit. The caterpillars are active when disturbed, wiggling vigorously or dropping to the ground on a thread. Larvae are usually mature by the end of May, and adults may be found any time from early June to mid-August. The adult moth is 1/2" to 3/4" long and mottled tan and brown. Other leafrollers may also be found on apple.
