General Description

provided by University of Alberta Museums
"A variable species that can be difficult to identify (Landry, et al. 1999). The forewing is yellowish brown to light grey with variably expressed darker grey or brown markings. When the markings are visible they typically consist of a basal patch and broad median band that both slant towards the anal angle and there is a triangular spot on the costa in the postmedian area. The hindwing and abdomen are dull greyish white and the thorax and head are concolorous with the forewing. The larva has a brown head with black lateral stripes while the body is pale yellowish brown to green with some darker stripes and pale pinacula (Duncan 2006)."

Argyrotaenia franciscana

provided by wikipedia EN

Argyrotaenia franciscana, the orange tortrix or apple skinworm, is a moth of the family Tortricidae. It is found from California north to Oregon and Washington.[2]

The length of the forewings is 5.6-9.9 mm. There are at least two, but sometimes more generations per year.

The larvae feed on a wide range of nearly 80 plants, including Malus, Prunus armeniaca, Persea americana, Rubus, Vaccinium, Vitis, Citrus x paradisi, Citrus limon and Pinus radiata. Early instar larvae skeletonize leaves under a silk shelter, while later instars roll, fold, or web leaves together or to fruits. Either the larvae or pupae overwinter. Overwintering can take place in dead leaves, mummified fruits, under buds or on weedy herbaceous plants near the host. Pupation occurs in the final larval shelter.
