Aethodelphax alatus
Aethodelphax alatus is a planthopper species in the family Delphacidae, originally described by Beamer in 1948 as Delphacodes alatus and later transferred to the new genus Aethodelphax. The species occurs in the midwestern and southeastern United States, where it is associated with native grassland habitats. Like other delphacid planthoppers, it likely feeds on grasses, though specific host associations remain undocumented in available sources.
Callirhytis quercusmodesta
Callirhytis quercusmodesta is a species of gall wasp in the family Cynipidae. The species induces galls on oaks (Quercus spp.) as part of its life cycle. Like other members of the genus Callirhytis, it exhibits heterogony, with alternating sexual and asexual generations that produce morphologically distinct galls. The species is known from the central United States.
Dectes texanus
Dectes stem borer, Texas prick, soybean stem borer
Dectes texanus is a native North American longhorn beetle (Cerambycidae: Lamiinae) that has emerged as a significant agricultural pest of soybeans and sunflowers in the Midwestern and Great Plains regions of the United States. Adults are characterized by antennae longer than their bodies and a pale gray coloration. Larvae tunnel inside plant stems from July through October, then girdle the stem base internally before overwintering, causing pre-harvest lodging and yield losses. The species has expanded its range and pest status dramatically since the 1980s, correlating with increased soybean acreage and adoption of no-till farming practices. Originally associated with wild hosts including ragweed and cocklebur, it colonized cultivated soybeans approximately 50 years ago.
Laevicephalus minimus
Laevicephalus minimus is a species of leafhopper in the family Cicadellidae, first described by Osborn and Ball in 1897. Originally placed in the genus Deltocephalus, it was later transferred to Laevicephalus. The species belongs to the subfamily Deltocephalinae and tribe Paralimnini. It is known from scattered records in the north-central United States.
