Grasshoppers of Wyoming and the West


Trimerotropis barnumi Tinkham

Trimerotropis barnumi

Trimerotropis barnumi is very similar to T. agrestis. It is known from sand dunes in Utah and other Great Basin states. We collected it in two different years from the same sand dune in northern Sweetwater County. It probably occurs on other sand dune areas in southwest Wyoming. Adults were collected on the 15th and 20th of August in an area of open sand and Rumex plants. It is not considered a pest species of grasshopper.
