• Speckled green fruitworm

  The adult is grayish beige with two purplish gray spots on its wings and a hairy thorax. The eggs are laid on the upper surface of the leaves.

• Pear plant bug (Green apple bug)

  The adult pear plant bug is brownish yellow with two dark bands on the thorax and the extremities of its anterior wings are yellowish in color.

• Dock sawfly

  The adult is bluish black with red legs. The larva is a smooth velvety green worm with white legs and a dark head.

• Climbing cutworms

  Adults are dark brown or grayish colored moths. Larvae tend to be smooth caterpillars with few hairs, brown or black head capsules, and bodies a dull gray-brown background color with stripes, spots, or dark brown, black, yellow or white splotches.

• Tufted apple bud moth

  Adult is an inconspicuous moth, varying from mottled gray at the wing base to brown at the wing tip, with a lighter colored margin along the wing's leading edge. Two or three groups of tufted scales can be seen on the top of the wings.

• Twospotted spider mite

  Adult and nymphal mites are yellowish to pale green with a dorsal pair of apparent dark "spots". Males are smaller than females and have a pointed abdomen. The female takes on an orange tinge in the fall.

• Brown stink bug

  Stink bug adults have a broad, flattened, shield-shaped body and a narrow head. The brown stink bug is brown to grayish-brown and slightly speckled.

• Apple (Lyonetia) leafminer

  The adult has narrow white forewings with extensive gray-black and brown markings apically wing margins are fringed with long hairs. The larva is whitish and generally concealed within the leaf mine.

• Winter moth

  Adult male has grayish-brown wings; the female has remnants of wings and so cannot fly. This, in combination with the female's large body, makes the legs appear to be long, and gives her the superficial appearance of a spider.

• Peach leaf curl

  The pathogen infects young undeveloped tissue of leaves and fruit. Infection is most severe when cool conditions prevent rapid development of the foliage. Infected leaves curl and blister, leaving them severely deformed.

• Shothole borer

  The adult is stocky with a hard black body and antennae, leg segments and tips of elytra reddish brown; its head is not visible from above.

• Lesser peachtree borer

  Adult is a clear-winged, metallic-blue moth that has two or more yellow bands across the abdomen, giving it a wasp-like appearance.

• Apple pith moth

  Head of adult is covered with white scales; forewings are narrow, mostly black or dark brown with white marks and usually with an irregular faint, rusty yellow line in the middle, and with two prominent black scale tufts.

• Eyespotted bud moth

  Adult forewings are bluish gray with a central cream-colored band and black spots. The chocolate brown larva has a black head and thoracic shield.

• Prionus borers

  Adults are robust, broad, somewhat flattened blackish to reddish brown beetles with antennae roughly half the length of their bodies.

• Sparganothis fruitworm

  Adult is a vivid yellow moth with grayish magenta V-shaped marks on the forewings and reddish orange lace-like markings. Larvae are pale green with yellowish-green head.

• European fruit scale

  The female is immobile and covered with a circular waxy shell that becomes dark gray over time and is elevated at the center. The adult male is brownish red with an elongated abdomen, long antennae and wings.

• Periodical cicada

  Adults are wedge-shaped, nearly black, with red eyes and red-orange wing veins. The clear wings are held tent-like over the body.

• Snowy tree cricket

  Adult somewhat resembles a field cricket, but is pale green in color and has a longer, more slender body and smaller head. Antennae are much longer than the body; males have stiff veins in their flat wings.

• Silver leaf

  Silvering of the foliage is the characteristic symptom. At first, silvering may be associated with only one or two major branches, but eventually the entire tree becomes silvery in appearance. When infection is severe the leaves may curl upward.
