Insect Notes from Laguna Beach, 
California 
By E. O. Essig, Division of Entomology 
University of California 
The following notes were made during the Summer Session 
at the Pomona College Marine Laboratory, Laguna Beach and 
vicinity during June and July, 1921. 
ORTHOPTERA! 
Two earwigs, Anisolabis annulipes Lucas and A. maritima 
Brun., were commonly taken in the canyons in damp places under 
stones, logs and in wet leaves. The former occured under stones 
close to the creeks. 
The cockroach, Arenivaga (Homologamia) erratica (Rehn), 
was taken under a large stone. The specimen taken was appar- 
ently full grown and a wingless male. A winged female was also 
collected. 
The mantids,Stagmomantis californica R & H and Litaneutria 
obscura Seudd., were both taken on the hills near the ocean beach 
during July 1921. 
The common tree cricket in the Laguna Beach region proves 
to be Oecanthus nigricornis var. argentinus Sauss. A number of 
these were taken during July. 
The red Jerusalem cricket, Stenopelmatus fuscus Hald., was 
taken in a rotten log in Niguel Canyon. The common species at 
Laguna Beach which regularly traverses the streets at night and 
may often be found in the morning, is S. longispina Brunner 
(Syn. S. irregularis Scudd.). 
The large blue-winged grasshopper, Leprus glaucipennis 
Scudd., proved to be a match for the most active entomologists and 
eluded many a net. The species measures from 2 to 214 inches 
long and the color matches perfectly the color of the soil on the 
hills, back from the ocean where it occurs. The blue under-wings 
easily characterizes it. 
THYSANOPTERA 
. Western grass thrips, Frankliniella (Euthrips) occidentalis 
(Pergande)*. A pale yellowish-brown species was abundant in 
the heads of Juncus xiphiodes Meyer growing in fresh water at the 
mouths of the canyons near the ocean.
