It was found by Kamp in the ice caves at Eagle Lake, Lassen National Forrest(?). 'Gryllo' as Kamp calls the insect, lives on the ice, and is believed to be the prehistoric ancestor of the modern cockroach and grasshopper. Its mouth parts are primitive -- no sucker or 'biter' like up-to-date pests. The National Museum in Washington has asked Kamp for a specimen to place in its collection".
