Apple curculio
Tachypterellus quadrigibbus
Curculio adults are mottled brownish, blackish, and grayish weevils or "snout beetles". They have rough wing covers and a conspicuous curved beak or snout. They move into apple plantings around the time of bloom and lay eggs in apple fruitlets. "Stings” from egg-laying are the most common damage caused by plum curculio. The slit cut in the apple’s skin by the female becomes a tan patch of apple skin with a distinctive shape. These scars can be 1/4" Wide or more, but are only superficial. The adults also feed on apple tissue. Early in the season, the damage is strictly superficial, not more than 1/8" deep, and typically heals over, leaving a scar in the fruit.
