Diastrophus rubi is a gall wasp which affects Bramble (Rubus fruticosus agg.). The galls is an elongated swelling, usually causing the stem to bend, with a bumpy surface, each bump containing a separate gall chamber. Often the old, vacated galls are found with multiple exit holes; these can persist for many years.

It is a bisexual species; after mating, fertilised eggs develop into females and unfertilised eggs into males. Males are rare in some populations, and the species may be moving towards a parthenogenetic life-cycle where males are absent.

Galls have been recorded on the following brambles:

• Rubus caesius – European dewberry
• Rubus fruticosus – bramble
• Rubus gillotii
• Rubus idaeus – red raspberry
• Rubus praecox
• Rubus seebergensis
• Rubus sulcatus
• Rubus ulmifolius – elmleaf blackberry
