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]

Range

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]

Ecology

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]

Taxonomy

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]
