LEAVES: Small compound leaves are shiny, resinous, and dark green when
young but can remain on shrubs for extended periods turning almost brown but
still viable. The resin odor is at once acrid to deter plant eaters and yet
pungently pleasant. The whole desert takes on this heavenly aroma after a rain
shower signaling a return of life and verdancy.
Zygophyllaceae -- Caltrop Family
One of the most amazing and beautiful insects that lives upon Creosote Bush is Creosote Bush Walkingstick (Diapheromera covilleae). Adults mature during the summer monsoon season and can most easily be found at night when their long, delicate antennae wave about almost constantly. They generally hang upside down.
