Loads of insects use the creosote bush
in some way. The larvae of a species (or two) of creosote gall midge
, for example, live in the leafy ball-like galls pictured below. The female midge fly deposits her eggs in the stem. (Other species deposit other places.) The plant produces the gall to heal the 'wound;' the eggs hatch and the larvae say: yum.

Other species of midge lay eggs in different areas/parts of the creosote bush. The corresponding galls look different. The gall below looks like it's composed mainly of crystallized sap.

The fruits of the creosote bush
(fruit = the thing that has/holds the seeds) are furry (not spiny) and white.
