• 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.

• Oncideres rhodosticta

  Mesquite Girdler

  Oncideres rhodosticta is a twig-girdling longhorn beetle (Cerambycidae: Lamiinae) native to the southwestern United States and Mexico. Adults emerge in late summer (August–September) and feed on mesquite foliage. Females engage in distinctive girdling behavior, chewing complete rings through the bark and cambium of living mesquite twigs to create oviposition sites in the dying distal portions. Larvae develop within the dead twigs, completing a one-year life cycle. The species is economically significant as a pest of mesquite in rangeland and agricultural settings.

• 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).

• Purshivora media

  Purshivora media is a species of aphid in the family Aphididae. It is a specialist feeder associated with plants in the genus Purshia, commonly known as bitterbrush or cliffrose. The species is native to western North America where its host plants occur in arid and semi-arid shrubland habitats. Like other aphids, it reproduces parthenogenetically during favorable conditions.
