In their description of the sexual generation of this wasp, based on an adult captured independent of a gall, Nicholls et al provide a speculative description and photo of a gall they put forward as a possible sexual generation gall. This gall closely resembles that of Arnoldiola atra. According to circumstantial evidence observed by Scott Egan (personal communication), the alternate generation of B pallida is likely an integral midrib gall. This speculation is supported by the life cycle of Bassettia flavipes, which is closely related and also produces integral midrib galls in its sexual generation and integral bark or stem galls in its agamic generation. Our entry follows this speculation until additional information is discovered.
