Arnoldiola quercus larvae



Some authors, including Roskam and Skuhravaá, consider this species an autonomous gall causer, living in buds of terminal shoorts. However, most state that it is an inquiline of Contarinia quercina. A problem then is that A. quercus is, but C. quercina is not, known from the Netherlands.

Skuhravá, Skuhravý & Jørgensen (2006a) describe the larvae as “whitish”, but Roskam described the colour as light red, and Kieffer (1909a) as: gregarious,red. The latter also describes the spatula: yellow, lobes elongated, triangular, incision angular.
