Melanoplus ligneolus Scudder

Firewood Spur-throated Grasshopper (Melanoplus ligneolus)

The Firewood Spur-throated Grasshopper was described in 1899 based on specimens that had been collected near the cities of Benicia and Berkely in Solano – and Alameda County of California / USA respectively.

The males reached sizes of about 1,7 cm long, the females were slightly larger, both sexes were yellowish light-brown colored.

The species is considered possibly extinct without any reasons for this assumption being mentioned.

Paraleptophlebia placeri Mayo

Placer’s Prong-gilled Mayfly (Paraleptophlebia placeri)  

This species was described in 1939.  

The species appears to have been quite widespread, it was originally found in at least three sites: Amador Creek, Dry Creek, Grass Valley Creek, and Jackson Creek in the Amador County, but was also found in other areas including Alameda County, El Dorado County, Marin County, Mariposa County, and Shasta County in California, Benton County, Josephine County, Lincoln County, and Union County in Oregon, as well as Grays Harbor County in Washington.  

The youngest specimens date to 1977, younger collections are not known, and it is possible that this species is already extinct.
