Liopteridae
Liopteridae is a family of parasitoid wasps in the superfamily Cynipoidea, comprising approximately 140 species across 10 genera. Members are primarily larval parasitoids of wood-boring beetles, with the first definitive host record confirming Paramblynotus koreanus as a parasitoid of the weevil Carcilia strigicollis. The family exhibits worldwide distribution with notable concentrations in the African Tropics and is associated with broadleaf forest habitats.
Mellinus abdominalis
Mellinus abdominalis is a species of digger wasp in the family Crabronidae, first described by Cresson in 1882. It is a rarely observed species native to North America, with confirmed records from Alberta, Canada. Like other members of the genus Mellinus, it is presumed to be a predator of muscoid flies, though specific biological observations for this species remain undocumented. The species is part of a small genus of solitary wasps that excavate burrows in sandy soil and provision cells with paralyzed fly prey.
