Andricus inflator f. sexual
Sexual galls are in oak twigs, and are hard and woody, causing knobbly swellings, which can persist for some time after being vacated. Inside is a long narrow larval chamber.
Similar galls in twigs are formed by the agamic Andricus curvator. This has a small spherical inner gall
We recommend that the gall is verified by an expert before submitting to NatureSpot - take good photographs, note the host species and, if possible, retain a specimen. To distinguish from other twig galls, it may be necessary to open the gall.
