Lasioptera rubi
The gall midge Lasioptera rubi produces galls in the stems of various plants of the Rubus family, particularly in Bramble stems. The gall takes the form of a swelling, green at first, later brown and hard. The swelling is quite rounded in shape and up to 5 x 2 cm. The gall surface sometimes has longitudinal fissures. Old galls with exit holes may persist on the stems.
An Ambrosia gall; a fungus is also involved in the gall formation
The gall-wasp Diastrophus rubi causes galls on bramble stems, but these are knobbly and with many chambers.
