The Gray Knospenwickler ( Hedya nubiferana ) is a butterfly ( moth ) from the family of Winder (Tortricidae).
features
The moths reach a wingspan of 15 to 21 millimeters. The color of the forewings is variable: the distal part is often dark gray with a grayish base color. Sex dimorphism is not pronounced. The gray bud moth can be distinguished from the very similar species Hedya pruniana by the location of two black dots. In H. nubiferana, these are located above the protrusion formed by the dark markings in the middle of the fore wing. In H. pruniana they can be found next to the ledge.
The caterpillars are dark olive-green to gray-green in color and reach a length of about 13 millimeters. The head is black, the forehead plate ( clypeus ) is whitish, the mouthparts are dark reddish-brown in color. The front edge of the prothorax is whitish and translucent. The prothoracic plate is pitch black and is divided by a thin center line that is the same color as the caterpillar body. The thoracic legs are black. Orange-brown gonads are visible in segment A5. The slightly gray and translucent bristle hairs are long and thin. The anal plate shows a blackish color that changes to a brown tone towards the middle. The belly legs are translucent and colored in the same way as the abdomen. The end plate of the anal bones is translucent, the ring of hooks is dark brown. The pusher bears a large black sclerite on the outside and a small grayish sclerite with two black markings on the back.
