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.
