Entomology

Texas Brownspotted Grasshopper

Psoloessa texana Scudder

Psoloessa texana, the Texas brownspotted grasshopper, was first recorded from Wyoming during the 1992 survey of the shortgrass prairies of southeast Wyoming. It is very similar in appearance and habits to P. delicatula. Eggs probably hatch in July. Nymphs overwinter in the third or fourth instar. Adults were found in May and early June. It feeds on grasses but it is not numerous enough to damage forage except when other early season species are very numerous.
