Species Aspila packardi - Cherry Fruitworm Moth - Hodges#3428

3428

Grapholita packardi Zeller, 1875 (1)

Steganoptycha pyricolona Murtfeldt, 1891

Enarmonia packardi

Specific epithet in honor of A.S. Packard (1839-1905) "who made so many contributions to my work on North American microlepidoptera." (1)

FWL ≈ 3.5-5mm (2)

Wingspan 8-10.5 mm. (3)

Adult: range in color from light to dark. Light individuals have silvery striae and darker contrasting fasciae, while dark individuals lack a well-defined FW pattern. Males have a conspicuous patch of dark sex scales on the dorsal surface of the HW. (2)

Larva: Late instar larvae are approximately 8-9 mm in length with a pale-reddish abdomen. The head is yellowish brown with darker mottling. The prothoracic and anal shields are brown. Pinacular are moderately large. An anal comb is present with 4-6 teeth. Larvae may appear similar to those of many other species. Cydia pomonella larvae can be separated from G. packardi by the absence of an anal fork and their larger size. Larvae of G. molesta are similar but generally larger. Larvae of G. packardi and G. prunivora are very similar, although the pinacula on the 8th and 9th abdominal segment are more prominent in G. packardi, and the abdomen of G. prunivora is more reddish, especially in preserved specimens. (2)

Widely distributed in eastern North America. It is also present in the Pacific Northwest (Washington and British Columbia) and likely other fruit-growing regions of the West. (2)

Type locality: Texas(1)

2-3 generations per year. Adults are present in May and June. (2)

Larvae feed on many common fruit crops in the families Rosaceae and Ericaceae. It is possible that hawthorn (Crataegus) is the native host. (2)

Females lay eggs singly on terminal shoot leaves. Larvae feed inside the shoots or fruit; Chapman and Lienk (1971) found considerable variation in feeding records suggesting that larvae behave differently on different hosts or that a species complex is involved. Overwintering occurs on the host in a cocoon and pupation occurs the following spring. (2)

Represented by two BINs (BOLD:AAA8742 and BOLD:AAA8743) with more than 3% sequence divergence between them; both barcode closer to Grapholita libertina (BOLD:ACC7713) than to each other.
