Ortholeptura valida

This attractive longhorn beetle (Ortholeptura valida) was fairly abundant this year in the Sierra Nevada between 5,000 and 7,000 feet.  This individual (measuring about an inch long , exclusive of the antennae) came to our light near Shaver Lake (above Fresno, California) a couple of moths ago. We also found a population above Wishon Reservoir (still Fresno County) in July.

Linsey and Chemsak (in the Cerambycidae of North America, Part VI. no. 2) list the host plants as Abies, Tsuga, Pinus, and Pseudotsuga. This individual probably came out of ponderosa pine or white fir - both fairly common around Shaver Lake q.v.
