Diplolepis ignota is a species of gall wasp (Cynipidae). Galls in which the larvae live and feed are formed on the leaves of several species of wild rose (Rosa). [1] [2] [3] Individual galls are single-chambered and spherical, but multiple galls can coalesce into irregularly rounded galls. [2] [3]
This species has been reported throughout most of the continental United States, [4] [1] [3] and in Canada from Alberta, Saskatchewan, and Manitoba. [2] [5] [6]
Diplolepis ignota galls have been reported from Rosa arkansana , R. blanda, R. carolina, R. virginiana, and R. nitida. [2] [3] Gall initiation typically occurs in August, and the galls remain attached to their hosts, with adults emerging from the galls the following summer. [2] Inquilines and parasitoids of the larvae include species of Periclistus (Cynipidae), Aprostocetus (Eulophidae), Eurytoma (Eurytomidae), and Orthopelma (Ichneumonidae). [2]
This species was first described as Rhodites ignota by Carl Robert Osten-Sacken in 1863. [4] It was subsequently determined that the genus name Diplolepis had priority over Rhodites. [7] Recent studies have shown that this species is very closely related to Diplolepis nebulosa and D. variabilis . [8]
