Tetrastichus asparagi Crawford, 1909 Tetrastichus coeruleus is a gregarious koinobiont wasp which can be used as a biological control agent for the common asparagus beetle.

[1] It was originally named Tetrastichus asparagi Crawford,[2] thus most of the literature about this species has been published under this other name.

[3] Tetrastichus coeruleus has populations which are infected with the parthenogenesis-inducing Wolbachia and populations which are not.

[4] On average, 4.75 T. coeruleus adults emerge per larva, though this ranges between 2 and 13 specimens per larva.
