Hyrmophlaeba
Hyrmophlaeba is a genus of tangle-veined flies (Diptera: Nemestrinidae) established by Camillo Rondani in 1863. The genus is currently treated as a synonym of Hirmoneura by some authorities, though GBIF and other sources list it as accepted. Species in this group are characterized by their distinctive wing venation with numerous crossveins creating a net-like pattern. The genus belongs to a family of medium to large flies whose larvae are internal parasitoids of other insects.
Neohirmoneura
Neohirmoneura is a genus of tangle-veined flies in the family Nemestrinidae. The genus was established by Bequaert in 1920. Taxonomic status remains contested: Catalogue of Life treats it as a synonym of Hirmoneura, while GBIF and iNaturalist recognize it as accepted. The genus is rarely encountered, with only 46 observations documented on iNaturalist.
Neorhynchocephalus
tangle-veined flies
Neorhynchocephalus is a genus of tangle-veined flies (family Nemestrinidae) first described by Lichtwardt in 1909. The genus comprises seven extant species and three fossil species. Members of this genus are parasitoids whose larvae develop inside grasshopper hosts. Neorhynchocephalus sackenii has been documented as a significant parasite of rangeland grasshoppers in western North America, with parasitism rates reaching up to 24 percent in field studies.
Neorhynchocephalus sackenii
tangle-veined fly
Neorhynchocephalus sackenii is a species of tangle-veined fly in the family Nemestrinidae. It is known primarily as a parasitoid of grasshoppers, with documented associations to at least two rangeland grasshopper species in western North America. The species constructs specialized respiratory pores in its host and has been observed to cause significant mortality in grasshopper populations, with parasitism rates varying from 0 to 40 percent in field studies.
Poecilanthrax sackenii
Poecilanthrax sackenii is a North American bee fly in the family Bombyliidae. The genus Poecilanthrax contains approximately 35 species distributed from Canada through Central America, with greatest diversity in the Great Basin region. Larvae of Poecilanthrax species develop as parasitoids within caterpillars of cutworms and armyworms (family Noctuidae). The species P. sackenii specifically has been documented as a parasitoid of grasshoppers, with the tangleveined fly Neorhynchocephalus sackenii (originally described as Sackenia sackenii) being a principal dipterous parasite of the valley grasshopper (Oedaleonotus enigma) and ebony grasshopper (Boopedon nubilum).
